Cross-family format translation: how SIGMA-RAW becomes JPG
The SIGMA-RAW source is interpreted as Sigma Foveon camera captures normally stored as X3F with layered-sensor data, then rebuilt for JPG as lossy JPEG-compressed pixels optimized for photographs and broad compatibility. Renaming the file suffix alone could never accomplish that translation.
Input read as Sigma Foveon camera captures normally stored as X3F with layered-sensor data. Output required as lossy JPEG-compressed pixels optimized for photographs and broad compatibility.

What the SIGMA-RAW source carries and the JPG output demands
What can fail when SIGMA-RAW specialized file format is interpreted
Foveon development has distinct color and noise behavior that a generic raw description cannot predict.
What JPEG image cannot safely promise
Repeated encoding introduces ringing or blocks, and transparent areas must become opaque.
How the JPG writer handles this route
The writer builds lossy JPEG-compressed pixels optimized for photographs and broad compatibility and labels the result as image/jpeg. The receiving application - Not the extension alone - Is the final compatibility test.
The delivery decision for this SIGMA-RAW to JPG route
JPG is the right pick once the next application explicitly lists it as accepted and its photos and compact web images role suits the job better than SIGMA-RAW does.
What changes between the SIGMA-RAW model and the JPG deliverable
- Because JPG compresses lossily, verify the actual playback or viewing quality rather than assuming an unchanged size means an unchanged result.
- Metadata handling differs between SIGMA-RAW and JPG; do not assume every application-specific field carries across untouched.
Acceptance evidence for the converted JPG
