Summary

Upload a GIF and instantly download a multi-size .ico file (16, 32, 48, 64 px) — no server, no account needed.

How it works

  1. Click "Choose GIF File" and select any .gif image from your device.
  2. The tool renders the first frame of the GIF onto four Canvas elements at 16x16, 32x32, 48x48, and 64x64 pixels.
  3. Each canvas is read as raw RGBA pixel data and encoded as a 32-bit BMP bitmap.
  4. A valid ICO file header is assembled in memory, referencing all four bitmap images.
  5. The finished .ico binary is offered as an instant browser download — no upload, no server.
