PEF
PEF is the camera RAW format of Pentax digital cameras. It stores unprocessed sensor data for later adjustment of exposure and color. PEF files need RAW-capable software, so they are often converted to JPG, PNG, or TIFF.

JPG
JPG is the most common file extension for JPEG images and the standard format for photos. It uses lossy compression that makes files small while keeping good visual quality, and every device, browser, and app can open it. JPG does not support transparency, and each new lossy save can reduce quality slightly.
What happens when PEF becomes JPG
Source format
PEF is the image source or target format for this conversion path.
Target format
JPG uses lossy compression and does not support transparency.
What changes
The PEF pixels are decoded and written using JPG compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when JPG supports them.
- Codec and quality implications
- JPG uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the PEF source.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a PEF file no larger than 1 GB.
- Confirm that JPG is selected as the target.
- Download the JPG file and check the result before deleting your source.
Troubleshooting
- The PEF file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The JPG file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
