Lossless pixel preservation. Alpha transfers cleanly. TIFF with LZW is smaller than uncompressed alternatives. Only the largest icon size converts by default.
TIFF is supported by professional imaging tools and print workflows. Browsers don't display TIFF natively.
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.
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.
Yes. TIFF supports alpha channels and icon transparency transfers correctly in tools that handle TIFF alpha (most professional ones do).
Yes, TIFF supports multi-page documents. Each icon size can become a separate page. This converter outputs the largest size as a single-page TIFF.

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.
