Your files stay on your Mac.
Convertessa decodes your Kodak RAW (.dcr) files and re-encodes them as JPG images at the resolution the camera captured. Choose a quality level to control the trade-off between file size and visual fidelity. EXIF metadata is stripped so the resulting JPGs carry no embedded camera or location data.
Drag one or more .dcr files — or an entire folder — into Convertessa. No account or internet connection required.
Choose JPG from the output format list and set quality to your preference. Higher values preserve more detail; lower values reduce file size.
Click Convert. Convertessa processes every file locally on your Mac and saves JPG output alongside the originals. Nothing is uploaded.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
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.

New formats, new features, and fixes — every release, on the record.
No. Convertessa runs entirely offline. Your .dcr files are read and written on your Mac and never sent to a server.
Yes. Because JPG is a lossy format, Convertessa lets you choose a quality level before converting. A higher value retains more detail; a lower value produces smaller files.
Yes. Drop a folder into Convertessa or point the CLI at a directory and every .dcr file inside is converted in one pass.
