TM2 to G3 conversion is the process of transforming an image saved in the TM2 raster format into the G3 image format, typically used for Group 3 fax-compressed images. This conversion re-encodes pixel data and compression headers so the image can be stored or transmitted in the G3 (Group 3) standard commonly used for black-and-white fax, archival, and specialized imaging workflows.

TM2 files generally use the MIME type image/tm2 and support high-resolution raster images. G3 files use MIME type image/g3fax and are encoded with Group 3 Fax compression tailored for monochrome images. TM2 is suited for detailed image capture, whereas G3 is optimized for fax and document transmission using standard fax codecs.
The G3 (.G3) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like TM2.
While specific technical details aren't available here, G3 files generally serve the purpose of storing image effectively within their domain.

TM2 files typically support higher color depth and are used for detailed raster images, while G3 is a compressed format primarily used for fax transmissions to reduce file size. G3 offers faster transmission and better compatibility in telecommunication environments compared to TM2. Choosing G3 over TM2 is ideal for applications needing smaller files and legacy device support.
Keep source TM2 files under 10–20 MB per page for fastest, reliable conversion; very large high-resolution TM2 images can slow processing or require downsampling.
To preserve readability, convert TM2 to G3 using adaptive thresholding or manual contrast adjustments rather than aggressive binarization; avoid excessive downsampling if text detail matters.
For batch conversion, process files in groups (for example, 50–200 pages per job) and test settings on a representative sample to confirm quality and file size before converting the full set.
Note format limitation: G3 is a bilevel (black-and-white) fax format—grayscale or color information in TM2 will be lost or dithered during conversion.

If you need lossless archival, consider producing a lossless copy (TIFF/PNG) from TM2 in addition to the G3 file, since G3 is optimized for fax transmission and not photographic fidelity.
