Quick Answer: How to Convert TIFF to ICO
TIFF is the Tagged Image File Format — photography and publishing's heavyweight. ICO is the Windows icon container holding multiple sizes in one file. Converting between them re-encodes the media with ICO's compression model, so output quality depends on the settings you pick in the converter.
