Why Convert PEF to PNG?
PEF (Pentax RAW) is typically produced by or used with Pentax Digital Camera Utility, Adobe Lightroom, for maximum post-processing flexibility from Pentax camera sensors. PNG is expected by virtually every image editor and platform instead, for graphics, logos, and screenshots needing sharp, exact detail — converting bridges that gap.
Our engine reads a file built around maximum post-processing flexibility from Pentax camera sensors and rebuilds it aiming to preserve this: lossless compression plus full alpha transparency support — rather than producing a generic, lowest-common-denominator result.
PEF (Pentax RAW) works well for maximum post-processing flexibility from Pentax camera sensors, but has a real limitation: unviewable in browsers and most apps without dedicated RAW software. Converting trades that for this: lossless compression plus full alpha transparency support.

Frequent Questions
Can I convert the file back from PNG to PEF afterward?
Only what PNG 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.
What happens to features specific to PEF that PNG 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 PNG's constraint is: larger file sizes than lossy formats for photographic content.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Do I need any special settings before uploading my PEF file?
No special setup is required — upload the file as-is. PEF (Pentax RAW) files meant for maximum post-processing flexibility from Pentax camera sensors convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
Will I lose anything converting PEF to PNG?
Converting to PNG means adapting to a real constraint: larger file sizes than lossy formats for photographic content. Anything PEF (Pentax RAW) carries — built as it is for maximum post-processing flexibility from Pentax camera sensors — that has no equivalent there won't make the trip, but the core content converts faithfully.
