How to Convert PEF to JPG Online and on Desktop
Import PEF photos from browser or desktop app
Open UniConverter Online in your browser and drag‑and‑drop a PEF file to start a quick single‑photo conversion. When you need to work with many RAW shots or very large Pentax files, launch the UniConverter desktop app and add entire folders for efficient bulk importing and management.
Choose JPG as output and set options where needed
In the online PEF to JPG converter, simply pick JPG as the target format for a fast, no‑setup conversion that suits quick previews and sharing. On the desktop version, also choose JPG but refine export parameters like resolution and quality, ideal for handling big batches with consistent professional results.
Start conversion and save your new JPG images
Click Convert in the online tool to process your PEF and instantly download a ready‑to‑use JPG, perfect when you just need one or a few files converted. In the desktop app, run the conversion for dozens of RAW photos at once, then save them locally in organized folders, ready for editing, archiving, or client delivery.
