PEF is the RAW image format used by Pentax digital cameras.
OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic. It is widely used in visual effects and computer graphics.
FreeFileConvert uses tuned encoding for PEF to EXR conversions, preserving clarity while trimming file size. Finished images open instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PEF files from desktop or tablet, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized EXR results on any device you rely on.
Process up to 5 files sized 1024 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent EXR images with dependable progress tracking.
