Favicon Generator
Generate every favicon size a site needs — from 16×16 up to a 512×512 Android icon — from one image.
Everything happens locally via the browser's Canvas API — your image is never uploaded to a server.
Choose Image or Drag & Drop
A square image (512x512 recommended) works best — non-square images will be center-cropped.
About this tool
Comprehensive documentation & audit utility guideEvery platform expects a different favicon size — browser tabs, iOS home screens, and Android app icons all pull from different files. This tool takes one source image and re-encodes it at every commonly-needed size via the Canvas API, so nothing is uploaded anywhere.
How it works
