Round corners individually or make organic blob shapes, with a live preview and copy-ready CSS — in your browser.
CSS
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Round all four corners together, or unlink them to shape each one independently. Flip on organic blob mode to use the elliptical eight-value syntax and make soft, asymmetric blob shapes — the kind that make hero sections and avatars feel less boxy.
The preview updates as you drag, and the copy-ready CSS is one click away. Everything runs in your browser. For a fill to match, try the blob generator.
It uses the elliptical 8-value border-radius syntax (e.g. 30% 70% 70% 30% / 30% 30% 70% 70%) to make soft, asymmetric blob shapes instead of simple rounded corners.
No — it is pure CSS generated in your browser.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
InfyTool is built by the same team as these free libraries.
