Free tools / Compress video
Shrink a video so it fits in a WhatsApp chat, an email, or a faster upload — without installing anything or sending your footage to someone's server. Pick how hard to squeeze; the video is re-encoded on your own device.
Drop in any video — MP4, MOV, WebM, whatever your camera made.
Choose a compression level. Balanced is right for most videos.
Download the smaller MP4. Nothing was uploaded anywhere.
Really free, no watermark, no account. The compression runs inside your own browser using the same engine that powers the Vairal editor — it costs us nothing to run, so we don't charge for it.
No. The file never leaves your device — the work happens in your browser's own memory. Close the tab and every trace is gone.
Typically 40–80% smaller depending on the level you pick and how the video was recorded. Screen recordings and phone footage compress the most.
The practical limit is your device's memory — a few hundred MB is comfortable on a laptop, a bit less on a phone. For very long videos, trim first, then compress.
Drop one long video into Vairal and AI finds the most viral moments, cuts each into a captioned 9:16 short, and polishes it — in 40 languages, free to start.
