Frequently asked questions

How do I convert PEF to PNG?: Upload your PEF file above and it is converted to PNG automatically. Then click Download. No software to install — it runs in your browser and on our server.
How do I open a PEF file?: PEF files often won't open in an ordinary photo viewer without specialist software. The quickest way to open one is to convert PEF to PNG here — upload your file and download a standard PNG that opens on any phone, computer or browser.
Can I use this as a PEF file viewer?: Yes — it doubles as a free online PEF viewer. Upload your file and the converted PNG is displayed right in your browser, so you can see the image without installing a PEF viewer or codec pack. Download the PNG if you want to keep it.
What is a PEF file?: PEF is Pentax's camera RAW format — the unprocessed sensor data your camera saves for maximum editing latitude. Because it isn't a standard image, most apps can't open it directly, so converting to PNG gives you a shareable picture.
Is the PEF to PNG converter free?: Yes — it is free, with no signup. Premium adds batch conversion (many files into one ZIP) and larger uploads.
Can I convert PEF to PNG without Photoshop or Lightroom?: Yes. Your PEF file is decoded with professional camera-RAW processing on our secure servers, so you don't need Photoshop or Lightroom — or any other software — installed. Upload the file, then download the finished PNG.
Will I lose quality converting PEF to PNG?: PEF is processed at full resolution. PNG output is lossless. For archival work keep your original RAW too.
