Round Image Corners
Round the corners of an image and export it as a transparent PNG, so it drops cleanly onto any background. Faster than opening a full editor when you just need a rounded avatar, card or thumbnail. It is free, needs no account, and adds no watermark to your result.

What happens to your file.
In the visual editor everything happens on a canvas in your browser. The outline is traced as a path, the image is clipped to it, and the result is written out with a real alpha channel so the corners are genuinely transparent rather than filled with a colour. The radius is a percentage of the shorter side, so the same setting looks right on a wide banner and on a small avatar; the pixel value it works out to is shown underneath. Process file rounds the corners on our server instead, with the radius in pixels: the curve is smoothed so the edge is not jagged, and the corners are cut into the transparency the picture already has, so a logo on a transparent background keeps it.
Where it stops: Transparency needs PNG or WebP. Saving as JPG fills the corners with the colour behind the image, because JPG has no alpha channel — the page warns you before that happens. In the visual editor, very large images are limited by what your browser can hold in memory; Process file handles them on the server.
Rounded, squircle or circle?
- Rounded is a plain rounded rectangle: four arcs joined by straight edges. The right choice for cards, thumbnails and screenshots.
- Squircle is the smoother shape used for app icons, where the curve starts further along each edge so there is no visible point where the bend begins.
- Circle crops the middle of the image to a circle, which is what a profile picture needs. Turn on "Crop to a square first" for the best result.
Choosing a radius
The radius is a percentage of the shorter side, so it behaves the same whatever size the image is. Around 5 to 10 per cent gives the gentle softening used on cards and screenshots; 20 to 25 per cent is the app-icon look; 50 per cent is fully round, which on a square image is a circle.
What people use it for.
Everything you need, without a paywall.
Common questions.
How do I round the corners of an image?
Drop the image in and open the visual editor, move the radius slider, and the preview updates as you go. Download when it looks right. For several images at once, set the radius and use Process file.
Will a transparent PNG keep its transparent background?
Yes. The corners are cut into the transparency the image already has, so a logo on a transparent background stays on a transparent background, now with rounded corners.
Why must the output be PNG or WebP?
JPG cannot store transparency, so rounded corners would be filled with a solid colour instead of being see-through. PNG and WebP both keep the transparent corners.
How do I make a perfect circle?
Choose the Circle shape and turn on "Crop to a square first". The middle square of the image is taken and rounded into a full circle.
Can I round only some corners?
Yes. Each of the four corners can be switched on or off, which is what you need for a tab, a speech bubble or a panel that meets an edge.
Will it work on a photo of any size?
Yes. The radius is a percentage of the shorter side, so the same setting looks right on a small avatar and a wide banner, and the full-resolution image is what gets saved — the preview is only scaled down to fit the screen.
Is the image uploaded?
Not with the visual editor, which draws and saves it in your browser. Process file sends it to our server, where it is written to a temporary folder for that request and deleted as soon as the job finishes.
