GifsOnTumblr is a Chrome extension developed by Damien Erambert that aims to solve the issue of Tumblr converting GIFs to WebP format. This conversion has negatively impacted glitch art and made it harder to save GIFs. With GifsOnTumblr, users can enjoy GIFs on their Tumblr blogs and dashboard once again.

This extension works by tweaking the dashboard to serve GIFs instead of WebP. However, it is important to note that your browser might still download both formats. As a result, pages with a large number of GIFs may experience slower loading times. It is worth mentioning that this is a limitation of GIFs themselves, and the developer cannot address this issue.
