TIFF to ICO Converter

Summary

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

How it works

1. Click "Choose TIFF File" and select any .tiff or .tif image from your device.
2. UTIF.js decodes the TIFF data in your browser, including multi-page and compressed TIFFs.
3. The decoded image is rendered onto four Canvas elements at 16x16, 32x32, 48x48, and 64x64 pixels.
4. Each canvas is read as raw RGBA pixel data and encoded as a 32-bit DIB bitmap.
5. A valid ICO binary is assembled in memory with all four sizes and offered as an instant download.

Use cases
