Your files stay on your Mac.
Kodak RAW (.dcr) is the proprietary raw image format written by Kodak digital cameras, capturing full sensor data before any in-camera processing. Convertessa reads .dcr files directly on your Mac and converts them to AVIF, JPG, PNG, TIFF, or WebP — no account, no cloud upload, no internet connection required. Drop a single file or point it at a whole folder and every conversion runs locally.
Drag a single Kodak RAW file or an entire folder of .dcr files onto Convertessa. Batch mode processes every file in the folder in one pass.
Choose AVIF, JPG, PNG, TIFF, or WebP from the output format list. Convertessa preserves the original resolution and strips embedded EXIF metadata on export.
Click Convert. All processing happens offline on your machine; nothing is sent to any server. Converted images are saved to the folder you specify.
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.
Yes. Pass a folder path to the CLI — convertessa ./raws/ --to png — and Convertessa converts every .dcr file inside it. The same batch mode is available in the app by dropping a folder onto the window.
Yes. Convertessa removes embedded EXIF and metadata from every output image — camera model, GPS location, and shooting settings are not carried into the converted file.
No. Convertessa runs entirely on your Mac with no internet connection required. Your .dcr files are never sent to a server — all decoding and conversion happens locally.
