When TIFF is the right output

TIFF is the archival / print-production format — lossless, multi-layer, supports CMYK for print, embedded ICC colour profiles. Scanned documents (some banks and legal archives still specify TIFF), print shops handling high-DPI artwork, and medical imaging (DICOM often wraps TIFF) are the real use cases. File sizes are large; TIFF is not appropriate for anything shown on-screen or shared via web.

What is PEF?
PEF is a Pentax camera RAW file, typically used for professional editing before export. Converting it to TIFF makes the file easier to open, share, or upload where PEF is not supported.

PEF vs TIFF — which format should I use?
PEF is a Pentax camera RAW file best for professional editing before export. TIFF is a lossless high-quality format best for printing, archiving, and professional photography. Use TIFF when a website, form, or app requires it, or when you need TIFF's specific strengths like smaller file size, wider compatibility, or transparency support.

How do I open PEF files?
On Windows: Photos, with the Raw Image Extension. On a Mac: Preview and Photos on recent macOS. Pentax RAW, and among the less widely supported — some editors that handle Canon and Nikon files will not read PEF.
