FAX to SK conversion is the process of transforming an image stored in a FAX format (typically TIFF-based black-and-white or Group 3/Group 4 encoded pages created by fax devices) into an SK image file used by Sketch or other software that utilizes the .sk image/container format. This conversion extracts raster pages from the fax encoding, preserves readable content, and repackages them into SK with appropriate compression and resolution settings for viewing or editing.

FAX files usually have the MIME type image/fax and are commonly encoded with Group 3 or Group 4 fax codecs. SK files utilize MIME types such as image/sk and are designed to support advanced compression algorithms. Typical use cases include scanned document archiving for FAX and high-quality image editing for SK.
The SK (.SK) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like FAX.

FAX files are traditionally black-and-white scanned images primarily used for fax transmissions. SK files, on the other hand, are more versatile image files that support better compression and color depth. While FAX files focus on transmission fidelity, SK format is better suited for editing and long-term storage.
Keep individual FAX pages under 5–10 MB to ensure fast processing and reliable quality; multi-page batches can be larger but process more slowly.
To preserve legibility, convert monochrome fax images as 1-bit or lossless grayscale SK rather than aggressive lossy compression.
For large archives, batch-convert files in groups of 20–50 pages to avoid timeouts and to simplify error handling.
Note format limitations: FAX is usually 1-bit black-and-white with Group 3/4 compression, so color information is not available; converting to SK won’t recreate color.
