Your files stay on your Mac.
Hasselblad FFF is a proprietary RAW capture format produced by Hasselblad medium-format cameras. Converting to TIFF gives you a lossless, universally readable file that retains the full resolution of your original capture. Convertessa strips EXIF and embedded metadata during conversion, producing clean files ready for any editing or archiving workflow.
Drag one FFF file or an entire folder into Convertessa. The app reads Hasselblad FFF files locally — nothing is uploaded.
Pick TIFF from the output format list. Convertessa will write a lossless TIFF for every FFF file in your selection.
Click Convert. Your TIFF files appear alongside the originals, with full resolution intact.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.

Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

Never. Convertessa runs entirely on your Mac. Files are decoded and written locally — no upload, no internet connection required.
