FAQ
SIG to QOI 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 QOI files?
QOIQOI (Quite OK Image) is a fast, lossless image format designed as a simpler alternative to PNG. It offers similar compression quality but with much faster encoding/decoding speeds, making it ideal for applications where performance matters.
