G4 to WEBP conversion is the process of converting images stored in the G4 (Group 4 fax/TIFF G4) format—an image compression scheme commonly used for black-and-white scanned documents and faxes—into the WEBP format, a modern image container that supports both lossy and lossless compression and is optimized for web delivery. This conversion translates the monochrome, usually bilevel G4 data into a WEBP image that can offer smaller file sizes, broader browser compatibility, and optional color or transparency support for web use.

The G4 format typically uses the image/tiff MIME type with CCITT Group 4 compression, commonly used in fax transmissions and scanned documents. WEBP uses the image/webp MIME type and supports both VP8 and VP8L codecs for lossy and lossless compression, respectively. WEBP is widely supported across modern browsers and optimized for web delivery.
The WEBP (.WEBP) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like G4.
While specific technical details aren't available here, WEBP files generally serve the purpose of storing image effectively within their domain.

G4 is an older fax-related image format primarily used for black-and-white images, whereas WEBP is a modern image format developed by Google that supports both lossy and lossless compression, including transparency and animation. WEBP offers superior compression efficiency resulting in smaller file sizes and better web performance compared to G4.
Keep original DPI: For scanned documents, preserve 300 dpi when possible to maintain legibility; downscale only if file size is critical.
Quality vs size: Use lossless WEBP for exact black-and-white preservation from G4; use lossy WEBP at quality 75–85 to reduce size while retaining readability.
Batch conversion: Convert multiple G4/TIFF pages to animated WEBP or convert each page to separate WEBP files; use command-line tools or batch uploader for large sets.
Format limitations: G4 is bilevel (1-bit) and optimized for monochrome; converting to WEBP may introduce color/greyscale if expanded—this can increase file size.
