G3 (Group 3) is a fax image format using ITU-T T.4 compression, the standard for document facsimile transmission.
EPI (Encapsulated PostScript Interchange) is a variant of EPS for image preview.
FreeFileConvert uses tuned encoding for G3 to EPI 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 EPI 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 EPI audio with dependable progress tracking.
G3 uses Modified Huffman (MH) run-length encoding optimized for black-and-white documents.
EPI files contain PostScript code with a TIFF or WMF preview image.
Upload your image file in the G3 format from your device, Dropbox, or Google Drive.
Select EPI as the output format and click Convert. Adjust optional settings if needed.
