Video editing tools have a reputation for being either fully featured and expensive (Premiere, Final Cut) or free but limited to thirty-second clips with a watermark. The Video Tools hub on Ai2Done sits between those extremes: a focused collection of utilities that handle the operations real people actually need — compress for sending in chat, convert because the recipient cannot open MKV, trim the first ten seconds of dead air, mute a noisy background, extract just the audio, add a subtitle track — without ever requiring you to upload the source file.
The compression and conversion tools are powered by ffmpeg compiled to WebAssembly. That sounds heavy, and the first load of the runtime is indeed ~30 MB; once cached, subsequent jobs start instantly. A typical 100 MB 1080p clip compresses to ~30 MB in roughly 45 seconds on a recent laptop, and the converter handles all the common container formats: MP4, MOV, AVI, MKV, WebM. Trim, resize and mute are similarly fast because they use ffmpeg's stream-copy modes where possible.
The hub also includes Extract Audio (MP4 → MP3 in one step), Video to GIF for sharing animations, Video to WebP for modern web-friendly animations, and Add Subtitles which burns or muxes an SRT track into the output. For phone-shot vertical video, the resize tool can quickly convert to landscape with a blurred background fill — the same trick TikTok-to-YouTube reposters use.
Privacy is the structural advantage. Video files often contain things you would never knowingly upload — faces of family members, screen recordings of internal dashboards, footage of your home — and the major browser-based competitors all upload the file to a server before processing. Ai2Done's pipeline executes inside the browser sandbox, so the file is read into memory, processed by Wasm, and written back as a downloadable blob without ever crossing the network.
Heavy users include educators who clip and re-caption lecture recordings, journalists who need to compress field footage before uploading to a newsroom server, and small business owners producing product videos for their own websites. Pair this hub with the Video Downloader hub when your source is a social media post, the Video Compressor hub for shrinking the output further, and the Audio Tools hub for working with the extracted soundtrack.
