Why Convert PEF to JPG?
JPG is the universal lossy-compressed raster format, built around everyday photos across every device and platform. Converting from PEF (Pentax RAW) — built around maximum post-processing flexibility from Pentax camera sensors instead — closes that gap.
JPG was built around everyday photos across every device and platform, which is precisely the gap PEF (Pentax RAW) leaves open, since it's designed around maximum post-processing flexibility from Pentax camera sensors instead.
Our engine reads a file built around maximum post-processing flexibility from Pentax camera sensors and rebuilds it aiming to preserve this: opens on virtually every device, browser, and piece of software — rather than producing a generic, lowest-common-denominator result.

Frequent Questions
Can I convert the file back from JPG to PEF afterward?
Only what JPG actually carries can come back — anything specific to PEF (Pentax RAW)'s role in maximum post-processing flexibility from Pentax camera sensors that didn't survive the original conversion won't reappear.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
What happens to features specific to PEF that JPG doesn't have?
PEF (Pentax RAW)'s real strength — captures the full sensor dynamic range with no in-camera processing baked in — has no equivalent once converted, since JPG's constraint is: no transparency support, and repeated re-saves degrade quality.
What's the real difference between PEF and JPG?
PEF (Pentax RAW) is built around maximum post-processing flexibility from Pentax camera sensors (Pentax's proprietary RAW format). JPG is built around everyday photos across every device and platform instead (the universal lossy-compressed raster format) — different enough that this is a genuine format conversion, not just a rename.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
