About this tool
Round the corners of photos, screenshots and app icons. Set the radius in pixels or as a percentage of the shorter side; 50% turns a square into a circle and a rectangle into a pill shape.
The corners become transparent, or you can fill them with a color when the image goes on a known background. You can also round only the top, bottom, left or right corners.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
Questions and answers
Why are the corners white after downloading?
JPG files can’t store transparency. Save as PNG or WebP, or leave “Save as” on Auto, which picks PNG when there are transparent corners.
What radius should I use for app icons or cards?
Around 18–22% of the shorter side gives the rounded-square look common for icons. Cards and screenshots usually look good at 3–6%.
Is Rounded Corners free?
Yes. Every tool on ImgImage is free to use, with no sign-up, no watermark and no limit on how many files you process.
