What changes when you convert TIFF to ICO

Standard icon sizes (16, 32, 48, 256) are generated by downscaling. TIFF's high-precision color tonemaps to 8-bit sRGB. Alpha transfers cleanly if the TIFF has an alpha channel.

When to use this conversion

  • Building favicons from TIFF logo assets
  • Creating Windows shortcut icons from TIFF design sources
  • Generating application icons from print-quality source material
  • Producing multi-resolution icons for desktop apps

Where the output plays

ICO is the native Windows icon format, universally supported.

About these formats

TIFF (Tagged Image File Format)

TIFF is a 1986 container format used throughout professional photography, print production, and archival imaging. It supports lossless compression, multiple pages, 16-bit-per-channel color, embedded color profiles, and high bit-depth grayscale. Print shops, medical imaging, and GIS systems expect TIFF.

ICO (Windows Icon)

ICO is the Windows icon format. A single .ico file can hold multiple resolutions (16×16, 32×32, 48×48, 256×256) and color depths simultaneously, letting the OS pick the best for context. Every browser serves favicons as ICO, and Windows desktop icons use it natively.

How It Works

  1. Add your TIFF files Drag TIFF images onto the page or click to pick them from your file browser. Batch uploads are fine.
  2. Choose ICO settings Pick quality or compression settings for the ICO output. Defaults match common target use cases.
  3. Convert in your browser The converter runs locally via WebAssembly. Nothing uploads. Progress shows per file so you know exactly what's happening.
  4. Download ICO files Grab each converted file individually, or download the whole batch as a single ZIP.

FAQ

Which TIFF page is used?

Only the first page. For multi-page TIFFs, other pages are ignored.

Will alpha transfer?

Yes, if the TIFF has an alpha channel. ICO supports full alpha and soft edges transfer cleanly.

Are my files private?

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.

Is there a file size limit?

There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
