Make Image Round

Make Image Round takes a rectangular photo and returns a clean circle with transparent corners, exported as PNG. The most common fit is the round avatar: profile pictures for Slack, Discord, GitHub, LinkedIn, or a team page, plus author headshots and contributor thumbnails that a site renders inside a circular frame. Because the corners are genuinely transparent rather than filled white, the result sits correctly on any background colour.

For web and app developers it is a quick way to pre-bake a circular asset instead of relying on CSS border-radius at render time, which matters when an image is reused in email, in a PDF, or anywhere CSS clipping is not available. It also suits small office and admin needs: a round logo mark, a circular badge for a slide or document, or a consistent set of headshots for an internal directory.

It is equally handy for one-off sharing and personal projects, such as a round icon for a community, a Notion or Trello avatar, or a circular stamp graphic. The optional border turns a plain crop into a framed medallion without opening a full editor.

Drag an image onto the dropzone or click to select one; the tool takes a single file at a time and accepts common raster formats (JPG, PNG, WebP). It first centre-crops the image to a square using the shorter side, then clips that square to a circle, so the centre of your picture is what survives the crop. You can leave the border width at 0 for a borderless circle, or raise it up to 20 pixels and pick a colour, which is stroked just inside the circle's edge.

Press Make Round to process, then download from the result panel. Output is always PNG so the transparent corners are preserved; the file is named after your original with a -round suffix. The panel reports the original and output sizes so you can see the change at a glance.

Everything runs in your browser using the canvas API. Nothing is uploaded and nothing is kept once the tab closes. Note what it does not do: it does not let you reposition or zoom the crop, choose an off-centre subject, output a square thumbnail, or produce JPG or WebP; the circle is always centred and the format is fixed to PNG.

The fixed centre crop is the main pitfall. Whatever falls in the middle of the square is kept, so a face placed off to one side, or a wide group shot, can lose the part you actually wanted inside the circle. Crop or reframe the photo first if the subject is not roughly centred, since this tool offers no manual positioning.

The output circle is only as large as the shorter side of your input: a tall 800x1200 image yields an 800-pixel circle, and a small source stays small. Start from an image at least as large as the avatar size you need, because enlarging a small circle later will look soft. Saving as PNG also means photographic circles can be noticeably larger in file size than a JPG would be, which is the trade-off for transparent corners.

Two smaller traps: the border is drawn inside the circle, so a wide border eats into the edge of your image rather than adding an outer ring; and an animated GIF is flattened to a single frame, since PNG output keeps only one image.

Open the downloaded PNG on both a light and a dark background and confirm the corners are truly transparent, with no faint white box or stray fringe at the circle's edge. Check that the subject is centred and fully inside the circle, that nothing important was clipped by the square crop, and that the edge looks smooth at the size you will actually display. If you added a border, verify the colour and that it has not covered detail you meant to keep.

Confirm the pixel dimensions match where the image will live; if the circle is smaller than the frame it will be upscaled and soften. Test it in the real destination, an avatar slot, a slide, an email, rather than judging it only in a preview, since rendering and scaling differ by context.

For official, financial, or legal use, such as an ID-style headshot, a verified profile photo, or a logo in a formal document, manually verify the final image meets the recipient's exact size and framing rules and that no required detail was cropped away. This tool applies a fixed centre crop and gives no guarantee about identity-photo standards, so a human check before submission is essential.
