Is there a reason for this?
And no, a GIF is a GIF, nothing else is a GIF, an mp4 is not a gif, webm is not a gif.
- SpaghettiCthulu 3y agoyou can say that, but the big gif hosting serve other formats with better compression by default.
- XCSme 3y agoAre you asking why a GIF is used, or why the 43 bytes are needed? I think a GIF is likely the smallest wide-supported resources format (force the browser request a URL to load a specific resource). The 43 bytes is the minimum size for a valid GIF, so the browser won't log an error loading the image and go through all load events. It looks like in modern browsers it's 35 bytes: https://stackoverflow.com/a/15960901/407650 https://stackoverflow.com/a/15960901/407650
