How to Convert PEF to PNG Online or on Desktop
Import your PEF RAW photos
Open the online converter in your browser, drag and drop a Pentax PEF file from your computer for a quick single conversion, ideal for fast sharing. For many RAW photos, launch UniConverter desktop and import entire folders to keep everything organized and ready for batch processing with stable performance.
Choose PNG as the output format
In the online tool, simply pick PNG as the target image format to convert your PEF photo with minimal clicks, perfect when you just need a clean PNG quickly. On UniConverter desktop, still choose PNG but also fine-tune output options like resolution or compression, giving you tighter control for print, web, or editing workflows.
Start the conversion and save your PNG files
Hit Convert in the online interface to process your PEF image on the server, then download the finished PNG straight to your device for instant use. On the desktop version, start conversion to process multiple RAW files at once and save PNGs directly to local folders or external drives for archiving, editing, or client delivery.
