X3F to PGX conversion is the process of translating Sigma/Foveon X3F raw image files into PGX (Portable Graymap Extended) format, preserving high-bit-depth linear or gamma-corrected pixel data for further processing. This conversion extracts raw sensor channels, metadata and color information from X3F and encodes them into PGX’s flexible high-precision grayscale or multi-channel structure suitable for archival, post-processing, or advanced image workflows.

The X3F file format typically uses the image/x-x3f MIME type and stores raw sensor data from Sigma cameras. PGX files use the image/x-pgx MIME type and employ wavelet compression codecs to reduce file size while maintaining image quality. Both formats serve niche purposes in photography and image processing workflows.
The PGX (.PGX) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like X3F.
While specific technical details aren't available here, PGX files generally serve the purpose of storing image effectively within their domain.
Our Online X3F to PGX Converter allows you to easily convert your X3F files into the PGX format without the need for complex software. Designed for photographers and professionals working with raw image data, this tool ensures quick and reliable conversion directly from your browser.
X3F is a raw image file format primarily used by Sigma cameras, containing unprocessed sensor data. In contrast, PGX is a wavelet-based image format optimized for compression and efficient storage. While X3F files are ideal for detailed editing, PGX files are better suited for archiving and quick viewing.
Aim to keep individual X3F files under 200–500MB for faster uploads and processing; very large raw captures can slow conversion or time out.
To preserve maximum quality, export PGX in the same or higher bit depth (16-bit or 32-bit float) and use linear/raw mode rather than applying gamma or aggressive tonal mapping.
When converting many files, use batch conversion with parallel processing but limit concurrent jobs to avoid high memory usage; convert in smaller batches for systems with limited RAM.
Note format limitation: PGX stores per-pixel channel data but does not encapsulate camera-specific demosaicing metadata — demosaic or color-profile adjustments may need a separate step.
