How do I convert PPM to MEF step by step?

Upload your PPM file to the converter, select MEF as the target format, and click 'Convert'. The tool bundles your pixel data into a MEF raw container. After processing, download the resulting .mef file and open it in any Mamiya-compatible imaging suite. No command-line or manual tag editing is needed.

Why should I convert from PPM to MEF?

PPM is a simple uncompressed RGB format used in Unix environments, while MEF is Mamiya's raw image format designed for professional photo editing. Converting PPM to MEF allows you to use the image in Mamiya's raw workflow tools and preserves the data in a metadata-rich container. It does not reduce file size; rather, it bridges compatibility gaps for photographers and archivists who need to ingest PPM files into raw-processing pipelines.

What data does the PPM to MEF conversion preserve?

The conversion preserves the exact RGB pixel values and image dimensions from the PPM source. Any alpha channel (if present) is dropped because MEF raw containers typically store only sensor data with a Bayer CFA pattern; the converter maps RGB to the MEF's raw buffer using the embedded color profile. If your PPM has 8-bit or 16-bit per channel, that bit depth is retained. EXIF and ICC metadata from the PPM (if any) are copied into the MEF header, but proprietary camera-specific tags are set to generic values.
