Should you convert ICO to TIFF?

A safe conversion when TIFF is what you need: both ICO and TIFF keep every pixel, so the picture itself doesn’t change.

Bear in mind TIFF is has patchy support: it works in photo editors, macOS Preview and Windows Photos, but not Chrome, Firefox or most upload forms.

ICO is a small container that holds the same icon at several sizes; TIFF is a high-fidelity format used by scanners, printers and archives. Use TIFF when a printer, publisher or archive asks for it, or for master copies of scans.

What changes when ICO becomes TIFF

Nothing is discarded

ICO and TIFF both keep every pixel, so the picture survives the move intact. You can convert back and forth as often as you like without it degrading.

Transparency is kept

ICO and TIFF both support transparency, so transparent backgrounds and soft edges come through unchanged.

Expect a much larger file

TIFF is far bigger for the same content. Choose it because something needs TIFF, not to send or store the file. ICO: A full favicon with every size is usually under 100 KB. TIFF: A scanned A4 page can be 20–50 MB.

This page is put together from our notes on each format, choosing only what is true of ICO and TIFF, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Changing a picture’s format is work your browser already knows how to do. Sending your photos to a server first only adds waiting and risk, so nothing is sent.

How to check for yourself

Worth knowing

About the ICO. Renaming a PNG to favicon.ico works in some browsers and silently fails in others. A real ICO holds several sizes so each place picks the right one.
About the TIFF. Multi-page TIFFs from scanners look like one picture in some viewers, so pages go unnoticed when converting.
DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.
