Upload a square photo as your profile picture and most platforms won't show you a square. They'll punch a circle out of it and throw away the corners — which is exactly where people tend to put their shoulders, their logo's edge, or half of their face.
So here's the fix, in order: crop to a circle before you upload, not after. Crop your photo to a circle → — runs entirely in your browser, nothing gets sent anywhere.
Why your "square" photo gets clipped into a circle
This isn't one platform's quirk. LinkedIn's own profile photo guidelines confirm it displays every profile photo as a circle — header, posts, comments, search, DMs — and tell you to center your face with room at the edges so the crop doesn't clip your chin or hairline. Discord does the same thing to every avatar, in every server and DM, and Slack's help center confirms the same — your photo "always displays as a circle," so it tells you to keep your face centered in the square you upload. Several other platforms — Google accounts, Zoom, WhatsApp — follow the same pattern, and none of them show you the circle before it's applied.
You upload a square (or worse, a rectangle they auto-square), and the platform stamps its own circular mask on top after the fact. If your face, logo, or product is sitting near a corner, it's gone.
The fix is boring but it works: crop to a circle yourself first, so you're choosing what stays instead of hoping the platform guesses right.
Get the composition right before you crop
A circle throws away more of the image than most people expect — the four corners of a square are the first casualty, but a true circular crop also nibbles the edges of the sides and top. LinkedIn's own guidance for its circular crop tells people to center the face with the eyes roughly a third of the way down from the top, not dead center — good advice for any circular avatar, not just LinkedIn's. Based on testing that composition across a few different platforms' masks, we'd add: keep whatever matters inside the middle 70% of the frame, with breathing room on every side, not just above and below.
If it's a logo instead of a face, leave equal padding on all four sides rather than letting it touch any edge — a logo that touches the edge of a square will absolutely get bitten by the circle.
How to crop to a circle in the browser (no signup)
- Open the Crop tool and drop in your photo. It loads locally — the file never leaves your device.
- Switch the crop shape to circle (or use a 1:1 square crop first if the tool doesn't do circles natively — see the note below) and drag the handles until your subject sits centered with margin on every side.
- Export. 800 x 800px is a safe default — it's the size LinkedIn itself recommends for a sharp result on high-DPI screens, and it comfortably clears every other platform's minimum too (see the table below).
- If the export is heavier than you expected — circular crops with transparency can bloat as PNG — run it through Compress before you upload. PNG keeps the transparent corners; JPEG will fill them with white or black, which looks wrong once the platform re-masks it into a circle.
That's it. No account, no watermark, no upload to a server somewhere to hold onto.
The size that actually works everywhere
You don't need a different export for every platform:
| Platform | Official minimum | Recommended |
|---|---|---|
| 400 x 400px | 800 x 800px | |
| Slack | 512 x 512px | up to 1024 x 1024px |
| Discord | doesn't publish an exact minimum | 512 x 512px covers it comfortably |
Export once at 800 x 800px and you clear every row in that table, including the high-DPI screens that would otherwise soften a smaller image.
Keep the file square (equal width and height) even if you've cropped to a circle with transparency — a non-square canvas is what causes the "why is my photo stretched" problem after upload.
Common mistakes that get an avatar clipped
- Cropping to a rectangle, not a square. A circle inscribes inside a square. If your source crop is a rectangle, the platform's own re-crop decides what gets cut, and you're back to guessing.
- Centering the frame, not the subject. A face sitting slightly off-center in a square photo looks fine — until a circle shaves the wider side down further than you planned for.
- Exporting too small. A 150 x 150px crop looked fine on your laptop and pixelated the second someone viewed it on a phone with a high-resolution screen.
- Flattening transparency to white. If your circle crop has transparent corners and you save as JPEG, those corners turn solid white (or black) — visible as a square ghost behind the circle on any platform with a dark theme.
The Bottom Line
Circular avatars aren't going away, and no platform previews the crop before it applies it. Crop to a circle yourself — subject centered, margin on all sides, exported square at 800 x 800px — and every platform's automatic mask lands exactly where you'd have put it anyway.
