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

RAW vs TIFF — which format should I use?
RAW is an unprocessed camera sensor 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 RAW files?
On Windows: Depends which camera made it — install the Raw Image Extension and try Photos. On a Mac: Preview handles most, depending on camera and macOS version. ".raw" is not one format. It is a generic extension covering several manufacturer formats, which is why one .raw opens and another does not.
