HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.
Pentax Electronic Format (PEF) contains raw sensor data from Pentax digital SLR and mirrorless cameras.
Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — its efficient compression makes sharing fast and storage minimal.
Reach for PEF when your priority is pentax camera post-processing — its uncompromising quality ensures every detail is preserved.

No, converting HEIF to PEF does not cause additional quality loss — PEF uses lossless compression. However, any artifacts already present in the original HEIF file will persist in the PEF output.
PEF files are typically 2-5x larger than equivalent HEIF files because PEF preserves all pixel data. This is expected and necessary for lossless quality.
Yes, PEF supports transparency. Alpha channel information from HEIF is preserved during conversion.
