FAQ
SIG to JXL Conversion
What are SIG files?
SIG is a raster image format used to store a handwritten signature as a picture, so that it can be placed on documents, forms, and letters in place of a pen signature. A file of this type holds a single bitmap, usually a scan, a photograph, or a capture from a signature pad, and carries no layers, no text, and no vector strokes. Signature images are normally small, often a few hundred pixels wide, with a white or transparent background and dark ink. The data is compressed JPEG, and some systems that produce the files, typically document management and e-signature software, store it in a modified byte order. For that reason, a generic image viewer may not recognize a .sig file until its contents are converted.
What are JXL files?
JPEG XL JXL is a modern image compression format designed to replace older formats like JPEG, PNG, and even WebP. It aims to provide superior image quality at smaller file sizes while supporting advanced features for both web and professional use.
