ICO and TIFF

The icon format of Windows, also used for website favicons. One ICO file can hold several sizes, up to 256 × 256 pixels. TIFF is lossless and accepted by print shops and archives.

What changes when you convert

  • Both formats are lossless, so the image itself doesn’t change. Only file size and compatibility do.

Other ways on a Mac

For one file now and then you may not need FileFlip. These work with what’s already on your Mac.

Open the ICO in Preview, choose File → Export, pick TIFF from the Format menu and click Save. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.

Good for a few files now and then.

Terminal

The sips command converts images in place or into a new file.

sips -s format tiff favicon.ico \
  --out favicon.tiff

Built into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
