BatchCrunch
Batch compress video in your browser — nothing uploaded
Drop a folder of video or audio files and BatchCrunch compresses or converts all of them using your own machine. It's ffmpeg compiled to WebAssembly, running inside the tab — your files are never uploaded, so there's no size limit and no waiting on someone else's server. No account, no subscription. 3 files per batch free; one-time $19 unlocks unlimited batches.
Maker here. This started as a folder of 40 screen recordings I had to shrink before
sending, and every online compressor wanting me to upload them one at a time.
So there's no upload step at all — the encoder is ffmpeg.wasm running in your tab, on your
CPU. Two consequences I like: there's no file size limit (nothing is being transferred),
and the privacy claim is verifiable rather than a promise — open your network panel and run
a batch, it stays silent.
Trade-off, stated plainly: WASM encoding is 2-4x slower than native ffmpeg. You're paying
in time for not uploading. For a folder you'd otherwise upload twice over, it's still faster
end to end.
Free for 3 files per batch, $19 once for unlimited. Would love to hear which format or
preset is missing for your workflow.
