Rounded corners baked into the file
CSS border-radius only rounds an image inside a web page. Baking the rounded corners into the PNG itself
means the image is rounded everywhere — avatars, app screenshots, email, slide decks and any tool that does not run
CSS. Set the radius, round all four corners or just some, and preview it live.
With a transparent background the area outside the curve is see-through, so the image sits cleanly on any colour;
pick white or black if you need a solid fill. It is drawn and clipped on a canvas in your browser and never
uploaded. For a perfect circle, Circle Crop is the specialised tool.
Frequently asked questions
Why not just use CSS border-radius?
CSS rounds corners only in the browser. Baking the rounded corners into a PNG means the image itself is rounded — right for avatars, app screenshots, email, slide decks and anywhere CSS does not reach.
Will the corners be transparent?
Yes — with the transparent background the area outside the rounded edge is see-through, so it sits cleanly on any colour. Choose white or black instead if you need a solid fill.
Is the image uploaded?
No. It is drawn and clipped on a canvas in your browser, and only you ever see it.
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.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
