PEF is the RAW image format used by Pentax digital cameras.
UYVY is a YUV 4:2:2 packed pixel format commonly used in video capture and processing.
FreeFileConvert uses tuned encoding for PEF to UYVY 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 UYVY 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 UYVY images with dependable progress tracking.
PEF files contain unprocessed sensor data from Pentax cameras.
UYVY stores color data as U0Y0V0Y1 sequences, halving horizontal chroma resolution.
