ABC to STP Conversion: FAQ

What are ABC files?

ABC (Advanced Bitonal Compression) is a proprietary image format designed by Lead Technologies for storing scanned documents of all types and sizes. The format is included in a larger imaging pack called LeadTools and its main advantage is the use of a 1-bit compression algorithm, allowing great image quality at a smaller file size when compared to other similar formats available. This translates into easier access, storage and transmission, which adds to the option of using lossless or lossy compression.
