About FITS
Flexible Image Transport System
The standard data format in astronomy since 1981, storing images and tables behind plain-text headers that record telescope and observation details. Convert from FITS to get a viewable PNG or JPG of telescope data; convert to it for astronomy software.
About WEBP
WebP
Google's image format, released in 2010, with a lossy mode based on the VP8 video codec, a lossless mode, alpha transparency and animation. A lossy WebP is usually smaller than a JPG of similar quality. Use it for images on websites, where every current browser supports it and smaller files load faster.
