The demo video in this post is compressed too. It went from 34MB to just 4MB, with almost no visible quality loss.
Be kind to community CDNs and other users. Now it only takes 4MB to watch instead of 34MB, which makes everything load much faster.
Instead of creating another FFmpeg wrapper, I built this using WebCodecs, which is up to 67x faster than FFmpeg WASM.
Run your videos through this before posting on Nostr. It cuts size by 50–90% with minimal quality loss, saves CDN bandwidth, and makes posts load instantly.
