"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

ABC to ICO 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.

What are ICO files?

ICO files contain the images used as icons for files, folders or programs on the Microsoft Windows platform.
