Favicon Generator
Turn any PNG, JPG, or SVG into a proper multi-size favicon.ico. Includes 16, 32, 48, 64, 128, and 256 px variants.
A favicon.ico isn't just one image - it's a container bundling multiple resolutions (16, 32, 48, 64, 128, and 256 px) so browsers, bookmarks, and taskbars each pick the sharpest fit. This tool takes a single PNG, JPG, or SVG logo, rasterizes it at every required size in your browser, and packages the result into one proper multi-resolution .ico file, no design software needed. SVG input in particular scales cleanly to all six sizes since it's vector-based rather than stretched from one bitmap.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Where do I put favicon.ico?
Drop it at the root of your site (e.g. /favicon.ico). Browsers pick it up automatically.
SVG input?
Yes - SVG is rasterized cleanly at each size.
Do I still need a link tag in my HTML?
Most browsers auto-detect /favicon.ico, but adding <link rel="icon" href="/favicon.ico"> guarantees it's picked up consistently.
Does it upload my logo?
No - every size is rendered locally on a canvas and packaged into the ICO in your browser.
Use this from your code
This tool is also a REST endpoint, so you can run it in a pipeline instead of by hand. Each call costs 2 credits and needs an API key. See the API reference for every parameter.
