How do I convert PEF to JPG?

Upload your PEF file above. It is converted to JPG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting PEF to JPG lose quality?

JPG is lossy, so some fine detail is discarded to make the file smaller. Raise the quality in Settings for a closer copy.

PEF or JPG: which should I use?

Use PEF for adjusting exposure and white balance with maximum latitude. Use JPG for photos you share, email, print or upload. Keep in mind the main drawback of JPG: no transparency, and every re-save loses a little more detail.

PEF is the RAW format of Pentax DSLRs. It stores the unprocessed sensor data for maximum editing latitude, so most apps can’t show it as a normal picture.
