A friend of mine spent twenty minutes generating a genuinely gorgeous portrait for his WhatsApp DP last month, wide cinematic shot, dramatic side lighting, the kind of image that would look great printed and framed. He set it as his profile picture and it looked terrible. Not because the image was bad. Because the parts that made it good, the wide framing, the negative space, the light falling across half the frame, are exactly the parts that a circular crop at 640 by 640 pixels throws away. What was left in the middle of the circle was an ear and part of a shoulder.

This happens constantly and almost nobody talks about why. Most advice about AI profile pictures is a list of prompts to paste, with no explanation of what actually breaks when a rectangular, wide angle image gets forced into a small circle. So this is less a list of prompts and more an explanation of the one thing that actually matters here: composition for a shape your prompt never mentions, followed by prompting techniques that consistently work and the couple of things that still go wrong even when you do everything right.

Why a circular crop is a genuinely different design problem

A WhatsApp profile picture is uploaded as a square, somewhere in the range of 500x500 to 640x640 pixels is the sweet spot, with higher resolution like 1080x1080 holding up better on newer screens. WhatsApp then masks that square into a circle everywhere it actually displays it, in chat lists, in call screens, at the top of a chat. The square you upload is not what people see. The circle is what people see, and the circle cuts away roughly the outer 15 to 20 percent of the square on every side. Anything sitting in the corners of your square image, which is a lot of area in a rectangle, simply does not exist to the viewer.

Most images, whether shot on a phone or generated by an AI model from a plain prompt, are not composed with that in mind. A typical portrait prompt produces a wide or standard frame with headroom at the top, shoulders spreading out at the bottom corners, and background filling the sides. All of that peripheral information, the top of the head, the shoulder line, the edges of the background, is precisely what a circular mask discards first. What survives the crop is a narrow, centered column of the image. If your face isn't sitting dead center within that inner region, with enough padding that a slightly imperfect crop still keeps your eyes and mouth intact, the result looks off in a way that's hard to name until you see it happen.

There's a second, smaller issue too: WhatsApp shows this image at a genuinely tiny size in most contexts, more like a coin than a photograph. Fine detail, subtle expression, anything that depends on the viewer being close to the image, just disappears. A profile picture has to read clearly at thumbnail size, which rewards simple, bold, high contrast compositions over busy or subtle ones. A picture that looks a little flat and obvious at full size often reads as clean and confident at 40 pixels wide. A picture that looks moody and layered at full size often reads as murky and unclear at 40 pixels wide.

Put those two things together, the crop and the scale, and the brief for a good profile picture becomes pretty specific: a single subject, centered, filling most of the frame, with generous room above the head and around the shoulders so a slightly off crop doesn't slice through anything important, rendered with enough contrast and simplicity that it still reads clearly when it's the size of a fingertip.

A vague prompt versus a specific one

Here's a prompt a lot of people actually type when they want a new profile picture:

Vague: "professional profile picture of a woman, high quality"

Run that through any capable image model and you'll get something. It'll probably be a person, probably wearing something plausible, on some kind of background. But the model has to guess at framing, at how tight the crop is, at where the head sits in the frame, at what the background looks like, and at what happens at the edges. Different runs give you wildly different crops: some too wide with the subject small in the middle of a lot of empty space, some cropped so tight the top of the head is already cut off before you even get to the circular mask. None of that is the model being bad. It's the prompt leaving every decision that matters for a circular avatar completely open.

Now the same idea, written with the crop in mind:

Specific: "Close up portrait of a woman, head and upper shoulders only, face centered in frame, looking directly at camera, soft even studio lighting from the front, plain solid dark green background, shot on an 85mm portrait lens with shallow depth of field, natural skin texture, square 1:1 composition with even space around the head"

Same subject, same general intent, but every phrase in the second version is doing a specific job. "Head and upper shoulders only" and "face centered in frame" control the framing so the important part of the image lands in the middle of what the circle will keep. "Plain solid dark green background" removes anything busy from the edges, which matters most because the edges are what gets cut off, so a plain background makes the crop forgiving instead of risky. "Square 1:1 composition" tells the model to fill a square frame instead of defaulting to a wider aspect ratio that will need aggressive cropping later. "Soft even studio lighting from the front" avoids harsh shadow that reads badly at thumbnail size. The result, run after run, comes out far more consistent, and critically, it comes out already shaped for the crop instead of shaped for a photograph that then has to be cropped down.

This is the actual lesson, more than any specific wording: a prompt for a profile picture needs to describe the frame, not just the subject. Most people writing prompts describe the person in detail and leave the frame to chance. Flip that emphasis and the results get dramatically more usable on the first or second try.

Framing and composition techniques that actually help

Write the crop into the prompt directly. Phrases like "close up," "head and shoulders," "centered in frame," and "square composition" aren't decoration, they're instructions the model treats as composition constraints. Leaving them out means the model defaults to whatever framing is most common in its training data for a "portrait," which skews wider than a good avatar needs.

Ask for generous headroom and shoulder room, not a tight crop. It feels counterintuitive, but you actually want a bit of breathing space around the subject in the source image, not a crop that's already tight. A tight crop from the model gives you nothing to work with if the eventual circular mask lands a few pixels differently than you expect. A looser composition with the subject filling maybe 70 to 80 percent of the frame gives you room to fine tune the crop afterward without cutting into the face.

Keep the background simple on purpose. A plain, solid, or gently gradient background does two things at once. It keeps anything distracting away from the edges of the frame, which is exactly where the circular mask does its cutting, and it keeps the thumbnail readable, since a busy background competes with the face for attention at a size where there's no attention to spare. Solid colors, soft gradients, or a softly blurred plain setting all work better here than a detailed scene.

Center matters more than symmetry. The eyes should land roughly in the upper third of the frame with the face itself centered left to right. You don't need perfect bilateral symmetry, real faces aren't symmetrical anyway, but the horizontal center of the composition should be the horizontal center of the face. Off center framing that looks natural and candid in a normal photo often looks like a mistake in a circle, because the circle removes the surrounding context that made the off center framing make sense.

Describe lighting explicitly, and keep it even. Soft, even, front facing light reads better at small scale than dramatic side lighting, even though dramatic lighting often looks more striking at full resolution. Hard shadows across half the face can render as an odd dark patch once the image is small and circular. Phrases like "soft diffused lighting," "even studio lighting," or "soft light from the front" push the model toward this.

Mention the lens and depth of field if you want a photographic look. Naming a focal length, like an 85mm portrait lens, and asking for shallow depth of field gets you a softly blurred background with the subject sharp, which is a very reliable way to separate a face from its background without needing a perfectly plain backdrop.

Ask for natural skin texture. AI portraits have a well known tendency to smooth skin into something plasticky. Explicitly asking for visible pores, natural texture, or subtle imperfections pushes back against that and tends to produce a result that reads as a real photograph rather than a render, which matters when the whole point is that this represents you.

Generate square, then check the actual crop before you commit. Even a well written prompt is a guess about where the model will place things. Before setting anything as a profile picture, actually preview it as a circle rather than assuming a square generation will be fine. What looks fine as a square thumbnail can still lose an earring, the top of a hairstyle, or part of a collar once the corners disappear.

Where a text prompt starts to struggle

A well built prompt gets you most of the way there, but there's a specific point where a general purpose prompt approach runs into a real limit, and it's worth being honest about it: consistent likeness.

Text to image models are generating a person, not photographing you. Every run is a new face that fits the description, and small changes in wording, or even nothing changing at all, can shift the outcome enough that the image doesn't look like the same person from one generation to the next, let alone look like you specifically. That's fine if you just want an appealing avatar and don't care whether it resembles your actual face. It becomes a real problem the moment the goal is a profile picture that people who know you recognize as you, since a WhatsApp DP is attached to your name and your contact card, not floating free as generic art.

This is the actual dividing line worth knowing before you start. If you want an original, stylized, or conceptual avatar and don't need it to resemble a specific face, a detailed text prompt run through a strong general model handles that well, and it's often faster than any other approach since you're not managing reference images at all. If you already have a photo of your actual face and want that likeness carried into a new setting, background, or style while still looking like you, a prompt alone is fighting an uphill battle. That's a job for a tool built specifically around a source face and a target image, because it's solving a narrower, harder problem: keeping identity markers like eye spacing and jawline intact rather than approximating a description.

Enhance AI has a dedicated tool for exactly that second case. FaceGen takes a clear photo of your actual face and a target image, whether that's a scene you generated separately with strong composition, a portrait style you like, or any other image, and blends your real face into it. It's the more reliable route any time the goal is "this needs to actually look like me" rather than "this needs to look good." A workable order of operations: use a detailed prompt in Playground to generate a well composed, centered, plain background portrait first, worrying only about framing and light, then run that result and a clear photo of yourself through FaceGen so the final image both has the composition you want and the face is unmistakably yours.

What still goes wrong even with a good prompt

Even a carefully written prompt doesn't guarantee a perfect result every time, and it's worth knowing what commonly still needs a fix rather than a full redo.

The most frequent issue is a slightly off center face where a clean regeneration would waste a token on an otherwise fine image. If everything about the portrait works except the face sits a bit too far to one side or too close to the top edge, that's a nudge, not a rebuild. The Change Region tool inside the Enhance AI image editor lets you mask just the area around the subject and regenerate that specific region without touching the parts of the image that were already working, which is a lot more efficient than starting over from the prompt.

The second common issue is something distracting near the edge of the frame, a stray object, a second person partly in shot, part of another chair, that's about to sit right in the zone the circular crop is going to keep. Since the outer part of a square gets discarded but the crop line isn't exact, background clutter closer to the center than expected can survive the cut. The Magic Eraser tool in the same editor removes an unwanted element cleanly without needing to regenerate the whole image around it.

The third issue, and the hardest one to fully prompt your way out of, is the likeness problem already covered above: a portrait that's well composed and well lit but just doesn't look enough like you. No amount of rewording the text prompt reliably fixes that, since the model was never working from your actual face to begin with. That's the case where FaceGen earns its place in the workflow rather than another round of prompt tweaking.

One more thing worth knowing, since it trips people up and it isn't a composition issue at all: prompts get screened before they're generated, and if a prompt gets rejected it happens almost instantly, within a second or two, before any actual rendering starts, so nothing is charged for it. If a job instead sits in a queue for a while before failing, that's a different, unrelated kind of failure, usually a busy queue or a temporary hiccup on the model's side, and it's worth just trying again. Our troubleshooting guide covers this distinction along with the other most common ways an AI generation goes sideways, if a result comes back wrong and it isn't obvious why.

A quick checklist before you hit generate

Describe the frame, not just the person: close up, head and shoulders, centered, square composition.
Ask for generous space around the head and shoulders rather than a tight crop.
Keep the background plain, solid, or evenly blurred so nothing important sits near the edges.
Use soft, even, front leaning light instead of hard side shadows.
Ask for natural skin texture to avoid the smoothed out AI look.
Preview the result as an actual circle before setting it as your DP, not just as a square.
If the goal is a picture that looks like you specifically, plan on pairing a prompt with a face based tool rather than relying on text alone.

FAQ

What size should I make my WhatsApp profile picture?

A square image somewhere between 500x500 and 640x640 pixels covers WhatsApp's actual display needs, and 1080x1080 gives you more headroom on high resolution screens without any real downside. What matters more than the exact pixel count is that the subject sits well inside the square, since WhatsApp always displays it as a circle and trims roughly the outer 15 to 20 percent on every side.

Why does my AI generated portrait look cut off once I set it as my profile picture?

Almost always because the image was composed for a rectangular or wide frame rather than a centered square, so parts of it that mattered, the top of the head, a shoulder, an earring, ended up sitting in the area a circular crop removes. Regenerating with explicit framing language, like "close up, head and shoulders, centered in frame, square composition," fixes this far more reliably than adjusting the crop after the fact.

Should the background be busy or plain for a profile picture?

Plain, almost always. A busy background does two things you don't want: it puts detail exactly where the circular crop is going to cut, wasting whatever the model rendered there, and it competes with your face for attention at a size where there isn't room for competition. A solid color or a softly blurred simple setting keeps the crop forgiving and keeps the thumbnail readable.

Can I use a regular text prompt to make a profile picture that actually looks like me?

You can get a good looking portrait that way, but getting one that reliably looks like your actual face is a different and harder task, since a text prompt is generating a person rather than working from a photo of you. If likeness matters, the more reliable path is generating or choosing a well composed image and then using a tool built around your actual face, like FaceGen on Enhance AI, to carry your real likeness into it.

What's the fastest fix if my portrait is good but slightly off center?

Regenerating the whole image from scratch is usually unnecessary for a framing issue like this. Masking just the area around the subject with the Change Region tool in the Enhance AI image editor and regenerating that specific region keeps everything that already worked while fixing the part that didn't.

My prompt got rejected instantly. Did I get charged for it?

No. Every prompt is screened before it's queued for actual generation, and a rejection that happens within a second or two means the prompt never reached the model at all, so nothing was charged. That's different from a job that fails after sitting in a queue for a while, which is a rendering issue rather than a content check. The troubleshooting guide walks through both cases in more detail.

Getting a profile picture right is mostly a framing problem wearing a prompting problem's clothes. Once you write the crop into the prompt instead of leaving it to chance, most of the frustrating trial and error goes away. From there, Enhance AI's image editor handles the small fixes, a shifted crop, a distracting background element, without forcing a full regeneration, and FaceGen is there for the times a picture needs to look unmistakably like you rather than just look good. Enhance AI gives you access to over 250 AI models including the full Flux family, Qwen Image, Seedream, Nano Banana 2, GPT Image 2, and Recraft V4, with free credits on signup and no card required, so it costs nothing to try a few framings before you settle on the one you actually keep.
