Favicon Generator

Upload one image, get every common favicon size + an .ico bundle.

How it works

  1. 1Upload a square image (PNG, JPG, WebP, or SVG).
  2. 2We resample it to every common favicon size.
  3. 3Download each PNG, the .ico bundle, and the recommended <link> snippet.

Use cases

  • Ship a complete favicon set for a new website.
  • Replace an old, low-res favicon with crisp 192/512 PNGs for PWAs.
  • Generate a multi-resolution .ico without installing imagemagick.

Frequently asked questions

Where is my image processed?

Entirely in your browser. Canvas resamples the source and the .ico is assembled in JavaScript — your image never leaves the device.

What's the best source size?

512×512 PNG with transparent or solid background. Larger is wasted; smaller resamples up and looks fuzzy at 256/512.

Does the .ico include high-DPI sizes?

The .ico bundle includes 16, 32, 48, and 64 px (the Windows convention). For Mac retina, use the standalone 180 px PNG with apple-touch-icon.
