Autocompressor is a free online tool that compresses videos, images, audio files, and GIFs to a target file size, aimed at size-limited platforms such as Discord and Gmail. It also supports Discord sticker and emote compression. The service uses AUTO-REZ technology, built on tools including FFmpeg, ImageMagick, Gifsicle, MozJPEG, and ECT. Premium tiers with higher upload limits and compression options are planned but not yet available.
