How to use Round Image Corners
- Add one or more pictures.
- Set the corner radius: 100% turns a square picture into a circle.
- Select Round corners and download PNG or WebP files with transparent corners.
How it works
The radius is a percentage of half the shorter side, so the same setting looks the same on every picture in a batch: 20% gives gently rounded corners, and 100% gives a circle from a square picture or a pill shape from a rectangle. The corners become fully transparent, with smooth (anti-aliased) edges.
Transparency needs a format that supports it, so the result is saved as PNG or WebP, never JPG. If you need a circle cut from a chosen part of a photo, Crop image has a circle option with a movable frame.
The work is done by your browser on your device. Your pictures are not uploaded, so there is no queue, no size limit set by us and no copy kept anywhere.
Example
App screenshots for a presentation: 12% radius on all of them at once gives a consistent, modern look on any slide background.
Frequently asked questions
Why is the result a PNG and not a JPG?
JPG cannot store transparency, so rounded corners would be filled with a solid colour. PNG and WebP keep them transparent.
How do I make a circular picture?
Use a square picture and set the radius to 100%. To choose which part of a photo ends up in the circle, use Crop image with the circle shape.
Can I round many images at once?
Yes. Every picture you add gets the same relative radius; download them as a ZIP.
Will the corners look jagged?
No. The edge is anti-aliased, so it stays smooth on any background.
Limitations
- All four corners get the same radius.
- Output is PNG or WebP only.
- Animated GIFs are saved as a single frame.
