Is my image uploaded to make the favicons?

The six sizes are drawn from your image on canvases in this tab and encoded as PNG files there. Our servers are not involved at any point.

Does my source image need to be square?

A square source keeps proportions tidy across all sizes. Non-square images are scaled to fit the longest side, then centered, so a wider banner becomes a centered favicon.

What formats can I upload?

JPEG, PNG, WebP, GIF, SVG, and AVIF all work. Vector formats like SVG keep the smallest sizes especially crisp, since they downscale without aliasing.

Can I download all sizes at once?

Yes. Click Download all to save the six PNGs one after another, with a short pause between them. Your browser may ask once whether this site can download multiple files.

Where do these sizes get used?

16 and 32 are browser tabs and bookmarks. 48 covers Windows desktop shortcuts. 64 is used for high-DPI tabs. 192 is the Android home-screen icon. 512 is the largest icon in a PWA manifest.

How it works

For each of the six target sizes the tool creates a fresh canvas at that resolution, scales the image to fit inside it and centers it with the Canvas API method ctx.drawImage(img, dx, dy, dw, dh) with high-quality smoothing, and encodes the result with canvas.toBlob("image/png"). Each file downloads through a short-lived blob: URL, no zip library required.

Processing runs in your browser

All PNG resizing happens locally in your browser tab using the Canvas API. Our servers are not involved at any point.
