How Does the PEF to JPG Converter Work?
The CompressFly PEF to JPG converter reads supported Pentax PEF camera files directly in your browser and creates a JPG from decodable RAW data or an available embedded preview. Pentax cameras have produced different PEF variants over time, so compatibility depends on the camera model, firmware, and file contents rather than the filename alone.
Retain the PEF source for future RAW adjustments, especially when white balance, exposure, or lens-specific processing matters. Inspect the JPG resolution, orientation, color, contrast, and edge detail after conversion. Files are handled locally one at a time or in bulk, with no server upload and no signup required.
What "in your browser" means
- Your PEF files are not uploaded to a server
- Conversion runs locally on your device
- Converted JPG images are downloaded directly from your browser
