"Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster."

SIR to WEBP 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 WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
