What you get
Drop a photo and the tool returns a round PNG with transparent corners. There are no settings to fiddle with: it takes the largest square that fits in the middle of your image, cuts a circle out of it, and makes everything outside the circle fully transparent. The edge is anti-aliased, so it looks smooth rather than jagged.
The output size equals the shorter side of your photo. A 4032 × 3024 phone photo becomes a 3024 × 3024 PNG; a 1080 × 1920 screenshot becomes 1080 × 1080. The file is named after the original with a -circle suffix.
When the subject isn't in the middle
Because the circle is always centred, a face at the edge of a group shot or a logo in a corner will be cut off. The fix takes one extra step:
- Open the photo in Crop Image and choose 1:1.
- Move the square so the face or object sits in the middle with a bit of space around it, and download.
- Drop that square here. Since it's already square, the circle will touch all four edges of your selection — what you framed is exactly what you get.
Leave some margin: anything in the corners of the square disappears in the circle. For a head-and-shoulders avatar, keep the chin and the top of the hair well inside the frame.
Do you actually need a round file?
Most social networks, messengers and team chat apps take a square profile picture and display it as a circle themselves. For those, uploading a square is better — if they apply their own mask on top of a transparent circle, the result can show thin artefacts at the edge. Make a square with Profile Picture (400 × 400) or 1024 × 1024.
A real round PNG is what you want when you control the layout:
- email signatures and documents;
- slides and presentations;
- a team or "about us" page on a website;
- stickers, badges and round logos;
- thumbnails in design tools that don't have a circle mask.
Transparency: where it works and where it doesn't
The corners are transparent, which is why the result is always PNG. JPG can't store transparency — if you convert the circle with PNG to JPG, the corners become white. That's fine for a white page, but on a coloured background you'll see a white square around the circle.
Some apps preview transparent images on black or grey, so the corners may look dark in a gallery or chat preview. The file is still transparent; drop it onto a page to check.
Better results
- Start from a good-sized photo. Avatars are shown small, but displays with high pixel density need at least 400–500 px to look sharp. Your round PNG keeps the full shorter side, so you can scale it down afterwards with Resize Image.
- Keep the file light. A large transparent PNG can weigh several megabytes. Resize it to the size you actually need before uploading.
- Swap a messy background. Run the photo through Remove Background, pick a solid colour there, then circle-crop the result: you get the classic avatar look — the person on a clean coloured disc.
- Very large images (over about 16.7 megapixels) are scaled down before cropping, because browsers can't draw bigger canvases. You'll see a note when this happens.
Other shapes and sizes
For rectangles in specific ratios use Crop Image. For small square icons, try Discord Emoji (128 × 128) or the Favicon Generator for website icons.
