What is a .tiff file?

TIFF is an image format for print, scanning and archiving. It can keep images without loss at high bit depths, in CMYK, and with several pages in one file.

Files are large and most browsers don’t display them, so TIFF is a format for working and storing rather than for sharing.

Questions about TIFF

Is TIFF lossless?

Usually, but it depends on the compression: a TIFF can also contain JPEG data.

What is the difference between TIF and TIFF?

None. It’s the same format with a shorter extension.

Why are TIFF files so large?

They often keep every pixel with little or no compression.

Is TIFF better than PNG?

For print, yes: it has CMYK and several pages. For the web, PNG is the one that works.
