Fast, instant PEF (PENTAX) to JPG conversion. No signup required. Just drop your .pef file and get .jpg in seconds.
Batch Settings
HDR data will be tone-mapped
Your PEF file may contain HDR (High Dynamic Range) data. JPG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Quality reduction ahead
PEF is lossless, meaning every bit of data is preserved. JPG uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your PEF file may contain MakerNote metadata. JPG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Your PEF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using JPEG Image's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where JPG supports it
The JPG file is saved and ready for download

Frequently Asked Questions
Should I use PEF or JPG?
It depends on your goal. PEF preserves full quality. JPG offers smaller files via lossy compression. Choose based on whether file size or quality matters more for your use case.
Is JPG higher quality than PEF?
Not necessarily. Your PEF file may contain HDR (High Dynamic Range) data. JPG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Quality depends on the compression type and settings, not just the format name.
Can I convert PEF to JPG on Mac and Windows?
