Convert TIFF to ICO
Turn TIFF scans and print files into ICO icons for favicons and Windows. Everything happens in your browser, so your images never leave your device.
Why convert TIFF to ICO?
TIFF keeps full quality, but files are huge and browsers, email and most websites don't handle them well. ICO is the format browsers look for at /favicon.ico and the one Windows uses for app and shortcut icons.
Favicons and Windows icons
Browsers still request /favicon.ico from websites, and Windows uses ICO for application and shortcut icons. Icons are square and the ICO format tops out at 256 × 256 pixels, so a square, simple TIFF works best; fine detail disappears at 16 × 16.
Where ICO files work
Every browser accepts favicon.ico, and Windows uses ICO for application and shortcut icons. Support in image editors is uneven.

Questions
Will converting TIFF to ICO reduce quality?
ICO stores icons losslessly, but the format tops out at 256 × 256 pixels, so start from a square TIFF at that size or below and keep the design simple enough to read at 16 × 16.
Can I convert several TIFF files at once?
Yes. Add as many TIFF files as you like and they're converted one after another on your device. There's no file-size or file-count limit beyond your device's memory, and you can download the results together as a zip.
Are my TIFF images uploaded anywhere?
No. The conversion runs in your browser, on your own device, so your images are never sent to a server. Once the page and converter have loaded, it keeps working even if your connection drops.
