TIFF files can be compressed or uncompressed. From the TIFF specification:

Baseline TIFF readers must handle the following three compression schemes:
  • No compression
  • CCITT Group 3 1-Dimensional Modified Huffman RLE
  • PackBits compression - a form of run-length encoding
Both of these compression methods are lossless, so of course don't compress nearly as much as JPEG, which compresses by throwing away information.
