TinyFiles Compressor converts images to WebP and MP4 videos to WebM, so they’re light enough for the web without opening an editor. It’s free.
Why it exists
I got tired of the tinyjpg.com routine: upload, wait, download, rename, repeat. Around the hundredth round trip I vibe-coded my own. Then I thought “what about videos?”, so now it does MP4 to WebM too. Scope creep, but the useful kind. macOS only for now.
