G3 (Group 3) is a fax image format using ITU-T T.4 compression, the standard for document facsimile transmission.
YUV is a raw video format storing luminance and chrominance separately.
FreeFileConvert uses tuned encoding for G3 to YUV conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload G3 files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized YUV results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent YUV audio with dependable progress tracking.
G3 uses Modified Huffman (MH) run-length encoding optimized for black-and-white documents.
YUV files contain uncompressed video frames in Y, U, V color space.
Upload your image file in the G3 format from your device, Dropbox, or Google Drive.
