SIR to GIF 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 GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
