"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."

SIR to PCX Conversion: FAQ

What are SIR files?

SIR is also known as a BYU-MERS format and is associated with images used by organizations such as NASA to store space captions of planet earth and data related to them. The format was developed by a group of researchers on Microwave Earth Remote Sensing (MERS), at the Brigham Young University (BYU) and is considered rare.

What are PCX files?

The PCX (Personal Computer Exchange) image file format is associated with PC Paintbrush, an image editing software initially designed for MS-DOS by ZSoft Corporation. At first, PCX files stored a limited range of colors but in time their range was extended to a 24-bit (true color) palette, and PC Paintbrush was adapted for Windows too. Though widely popular during the days of MS-DOS, the PCX format in time lost its appeal and was gradually replaced by formats such as JPEG and PNG.
