When TIFF is the right target
TIFF is the standard interchange format for print, publishing, scientific imaging and archives. Converting a GIF’s frames to a multi-page TIFF is useful for importing an animation into tools that expect page sequences — document management systems, OCR and fax software, image-analysis tools, or print layouts.
Both compression options are lossless. Deflate (Adobe-style zlib) is understood by Photoshop, GIMP, Affinity, macOS Preview and libtiff-based tools; choose None only for very old or specialised software, as files will be much larger.
