How PENTAX-RAW turns into PNG: cross-family format translation
The PENTAX-RAW source is interpreted as Pentax camera raw captures found as PEF, PTX, or sometimes DNG depending on model settings, then rebuilt for PNG as losslessly encoded pixels with full alpha transparency. Renaming the file suffix alone could never accomplish that translation.
Input read as Pentax camera raw captures found as PEF, PTX, or sometimes DNG depending on model settings. Output required as losslessly encoded pixels with full alpha transparency.

PENTAX-RAW source facts versus PNG output requirements
What can fail when PENTAX-RAW specialized file format is interpreted
These containers do not guarantee identical metadata, compression, or Custom Image interpretation.
What Portable Network Graphics cannot safely promise
PNG is inefficient for many photographs, and indexed optimization can reduce a smooth palette even without JPEG-style loss.
How the PNG writer handles this route
The writer builds losslessly encoded pixels with full alpha transparency and labels the result as image/png. The receiving application - Not the extension alone - Is the final compatibility test.
When to actually choose PENTAX-RAW to PNG
Choose PNG when the next app explicitly accepts it and its lossless images and transparency role fits the job better than PENTAX-RAW.
What changes between the PENTAX-RAW model and the PNG deliverable
- PNG supports alpha transparency that PENTAX-RAW never had, so any transparent areas in the result are newly created, not carried over from the source.
- Metadata handling differs between PENTAX-RAW and PNG; do not assume every application-specific field carries across untouched.
Acceptance evidence for the converted PNG
Record the PENTAX-RAW evidence before conversion
Identify the actual format and camera, then compare color, lens correction, crop, highlights, and metadata.
Test the PNG file in its receiving workflow
Inspect transparent edges, gradients, exact dimensions, color, and small text at 100%.
