As with PNG vs JPEG, the difference between TIFF and JPEG is that the former is better quality but the latter is faster. TIFF is lossless, so none of the image quality is lost during compression. The downside is that the file is much bigger than a JPG, and this can cause websites to load slowly. TIFF files are great if you need to edit large files and want the highest quality possible. They are preferred by many developers and graphic designers, but if the resulting images find their way onto the web, especially on social media sites or portfolios, they will often be compressed using JPG.
