FAQ
SIG to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
