Why Convert PEF Files?
PEF is Pentax’s RAW format that most devices and non-Adobe software can’t open. Convert to JPG or PNG to view your photos on any device.
Social platforms reject PEF uploads. Convert to JPG for web-ready photos that post and display correctly everywhere.
PEF files are large. Converting to JPG cuts size dramatically while keeping excellent quality for sharing.
Convert PEF to TIFF to preserve the sensor’s full dynamic range and colour depth for editing and print.
Convert a full card of PEF files to JPG or PNG in one pass, ready to deliver or archive.
Convert PEF files directly in your browser — no Photoshop, no plugins, no downloads. Files up to 10 MB are always free, and converted files are deleted from our servers within 24 hours.
