TIFF to ICO Crop Converter
Load a TIFF, drag the crop handles to isolate the exact region you need, preview the result, then download a multi-resolution ICO file with 16×16, 32×32, and 48×48 variants. Everything runs in your browser — your image never leaves your device.

What This Tool Does
This tool loads a TIFF image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area into a multi-resolution ICO file. No server upload is required. The full workflow — loading, cropping, and ICO encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. TIFF files are decoded using URL.createObjectURL combined with img.decode(), ensuring the canvas always receives complete pixel data before the crop overlay is drawn. The output is a single .ico file containing 16×16, 32×32, and 48×48 pixel variants, the three sizes expected by Windows and web browsers for favicons and application icons.
Who This Is For
- Web developers creating a favicon from a TIFF logo or brand asset
- Windows application developers who need an ICO file from a high-quality TIFF source
- Designers who want to extract a specific region of a TIFF to use as an icon
- Anyone who needs to convert a TIFF to ICO without installing Photoshop or dedicated icon software
