Converting TIFF to ICO produces Windows icons from TIFF source material. Useful when design work is done in TIFF (common in print-focused studios) and the output needs to become a favicon or desktop icon.

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.
ICO is the native Windows icon format, universally supported.
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 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.
Only the first page. For multi-page TIFFs, other pages are ignored.
Yes, if the TIFF has an alpha channel. ICO supports full alpha and soft edges transfer cleanly.

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.
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.
