Can I make a circular image?
Yes. Set the radius to 50%. A square image becomes a circle; a rectangle becomes a pill shape. Crop to a square first if you need a perfect circle.

Round Image Corners
Round the corners of any image, up to a full circle. Free, no sign-up, and your image never leaves your device.
Rounding image corners means cutting each corner of a rectangular picture along a curve and making the cut-away area transparent, so the image sits on any background with soft edges. This tool sets the curve as a percentage of the image’s shorter side, so the same setting looks consistent on a wide banner and a square photo — and at 50% it turns a square into a circle and a rectangle into a pill.
How to round the corners of an image
- 1
Add your image
Choose a file, drop it on the box, or paste a screenshot.
- 2
Set the radius
Around 4–8% gives the soft look of app cards, 12–20% a friendlier rounded tile, 50% a circle or pill.

Download the PNG
The result is always PNG, because only PNG (or WebP) can store the transparent corners.
Why the output is a PNG
JPG has no transparency: if you saved rounded corners as JPG, the corners would be filled with white or black and would show as a box on any other background. PNG keeps them see-through. If your image was a photo, the PNG will be larger than the JPG — that is the cost of the transparency.
Where rounded corners are used
Rounded images look more finished on screens, which is why most interfaces use them. Common uses:
- Screenshots for blog posts, documentation and slide decks.
- Product and app images for landing pages and store listings.
- Circular profile pictures and team photos (50% on a square image).
- Thumbnails for portfolios and newsletters, where CSS border-radius is not available.
Matching a design system
Designers often specify radius in pixels. To match one, divide the pixel radius by the image’s shorter side: a 16 px radius on an image that is 800 px tall is 2%. Because the setting is relative, resizing the image later keeps the corners in proportion.
Imagelier’s main tool
Need to change the text in an image?
Rounding a screenshot for docs or a launch post? If a label or button text needs updating first, the editor can change it in place. Imagelier erases the old words, rebuilds the background and sets the new text at the original size, weight and color — no Photoshop needed.
Questions
Can I fill the corners with a color instead of transparency?
Not in this tool. Place the PNG on a colored background in your design or slide software and the corners will show that color.
Does it reduce quality?
No. Only the corners are cut; the rest of the image keeps every original pixel.
Is my image uploaded?
No. It is processed in your browser and never sent to a server.
