About the Favicon Generator
A favicon — the little icon in the browser tab — is a small detail that makes a site look finished and professional. But browsers and devices want it in several sizes, and making each one by hand is tedious.

How to use the Favicon Generator
- Add your source image (ideally square) by dragging it in or browsing.
- The tool generates favicons in the standard sizes.
- Download the favicon files.

How the Favicon Generator works
This tool processes your pictures using the browser's built-in Canvas API and standard image codecs for JPG, PNG and WebP. Resizing, cropping, conversion and compression all happen on your own device, so the image data is never sent to a server. Compression balances file size against visual quality using established lossy and lossless techniques appropriate to each format.
Tips & best practices
- Start with a square image at least 512x512 pixels so every size comes out crisp.
- Keep the design simple and bold — favicons are tiny, so fine detail disappears.
- Include the various sizes so the icon looks right in browser tabs, bookmarks and on mobile home screens.
Standards & accuracy
Uses the browser's native Canvas API and standard web image formats (JPG, PNG, WebP) — images are never uploaded.
For the best results, resize an image to the dimensions you actually display before compressing, and choose WebP for the web where a smaller file at the same quality is the priority.
