RLE is a bitmap format using run-length encoding compression.
G3 (Group 3) is a fax image format using ITU-T T.4 compression, the standard for document facsimile transmission.
FreeFileConvert uses tuned encoding for RLE to G3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload RLE files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized G3 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 G3 audio with dependable progress tracking.
RLE compresses repeated pixel values into count-value pairs for efficiency.
G3 uses Modified Huffman (MH) run-length encoding optimized for black-and-white documents.
Upload your image file in the RLE format from your device, Dropbox, or Google Drive.
Select G3 as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
