How to convert PEF to PNG
- Add your .PEF file - drop it in the box above or click to browse.
- Convert it to .PNG in a few seconds.
- Download your new .PNG file.
What to expect
- PNG from a developed raw is large - a 16-bit PNG from a 24 MP Pentax body can exceed 100 MB; use 8-bit if file size matters.
- Exporting to PNG discards the 12- or 14-bit raw flexibility; always keep the original
.pefas your master file. - EXIF metadata (camera model, exposure settings, and GPS on equipped bodies) transfers to the PNG - strip it before publishing if you need to remove location or camera details.
Frequently asked questions
Is the PNG output actually lossless?
The PNG file itself is lossless, but developing the raw involves irreversible choices such as white balance and tone mapping. The PNG is lossless from that point forward, not a bit-for-bit copy of the raw sensor data.
Should I export at 8-bit or 16-bit PNG?
Use 8-bit for web sharing or general use - it is significantly smaller. Choose 16-bit only if you plan to continue editing the file in Photoshop or GIMP where shadow and highlight recovery matters.
Can I batch convert a folder of PEF files to PNG?
Yes - darktable and RawTherapee both handle batch export via their queue, and XnView MP has a dedicated Batch Convert dialog that processes entire folders at once.
Why is PEF to JPG more common than PEF to PNG?
JPG produces far smaller files and is universally accepted for photos. PNG is only preferable when you need a lossless intermediate for further editing.
