What this tool does
Rounded Corners & Circle Crop runs entirely in your browser: set independent corner radii (or link them), or hard-crop to a centered perfect circle using the shorter side; optional inside border stroke; checkerboard live preview; export transparent PNG or quality-tunable WebP. Built for avatars, icons, and listing assets—local only, no uploads.
How to use
- Click, drop, or paste (Ctrl/Cmd+V) one image.
- Pick rounded rectangle or circle; tune radii and optional border.
- Check the preview, then export PNG or WebP (huge images auto-scale).
FAQ
Do images upload?
No. Decode, crop, and export stay in your browser.
How does circle crop work?
Diameter equals the shorter side; we center-crop to a hard circle with transparent outside—not letterboxed.
Is the border inside or outside?
Inside the path (clipped double-width stroke) so the canvas size stays the same.
Does WebP keep transparency?
Yes when the browser supports WebP alpha. Choose PNG for lossless.
