How to round image corners
Add your images
Drop your JPG, PNG, WebP, AVIF or HEIC files onto the page, or click to browse.
Set the corner radius
Pick a radius in pixels — the same radius applies to all four corners of every file in the batch.
Download the rounded images
Download each rounded PNG, or the whole batch as a ZIP — named with a -rounded suffix.
Frequently asked questions
Why does the output come as PNG?
Rounded corners are made of transparency — the area outside the radius must be see-through. PNG stores alpha losslessly, so corners are genuinely transparent instead of filled with white or another background color.
Do I have to upload my images?
No. Corner rounding runs entirely in your browser — your files never leave your device.
Will the corners look jagged?
No. The corner edge is anti-aliased — partially transparent pixels smooth the curve, so it looks clean on any background, light or dark.
Can I round the corners of a batch?
Yes. Drop multiple files and all get the same corner radius — processed all-or-nothing.
What is the file size limit?
Single files up to 25 MB.
Square corners vs rounded corners
Here is what each format is for, and when converting images with rounded corners is the right move.
What is Rounded-corner image?
The same picture with a transparent curve at each corner. The image keeps its size; only the corner pixels become see-through.
When you need it
Round corners for avatars, app icons, UI screenshots and cards that sit inside rounded layouts. The transparency is real — the image composites cleanly over any background. On a pure white page the difference is invisible; over color or imagery it is obvious.
