How Does the MOS to JPG Converter Work?
The CompressFly MOS to JPG converter attempts to decode supported Leaf and Mamiya digital-back files directly in your browser and renders a JPG from the available image data. MOS files can vary across camera systems, digital backs, and capture-software generations. A converted JPG may be based on decoded medium-format RAW data or an embedded preview when that is the usable image in the file.
Large MOS captures and their previews can have different pixel dimensions or processing, so compare the JPG resolution, crop, orientation, color, tonal transitions, and fine detail. Keep the MOS file for later work in compatible professional RAW software. Processing remains local for individual photos or batches, with no server upload or signup.
What "in your browser" means
- Your MOS files are not uploaded to a server
- Conversion runs locally on your device
- Converted JPG photos are downloaded directly from your browser

Does JPG retain the RAW editing data in a MOS file?

Will the JPG look the same as a Capture One export?
Not necessarily. Different software can interpret camera data and color settings differently. Review the JPG preview if matching an existing edit is important.

Is there a file size limit, and are my MOS files uploaded?
Your MOS files are processed locally in your browser and are not uploaded to a server, so there is no server upload limit. The practical limit depends on your device's available memory and processing power, especially for very large images or batches.
