Video compressor · 100% in your browser · Never uploads
Compress any video — right in your browser. It never uploads.
Shrink MP4, MOV, and WebM files for WhatsApp, email, or Discord. Free, no watermark, no signup. Your video is processed on your device and never leaves your browser.
Popular in India for one reason: you can compress a video for WhatsApp without uploading it to any website first.
How it works
Three steps. Nothing leaves your device.
Drop your video
Drag a clip in or tap to pick one — MP4, MOV, WebM, MKV, AVI. It loads into your browser, not a server.
Pick a target size
Choose a preset (WhatsApp, Email, Discord…) or set a custom size and resolution. We compute the right bitrate for you.
Download the smaller file
Compression runs on your device with a live progress bar. Preview the result and download — all without an upload.
The result
A 92 MB clip becomes a 14 MB clip.
Pick the “WhatsApp (16 MB)” preset and a 30-second 1080p clip drops from 92 MB to about 14 MB — small enough to send, still sharp enough to watch.
92 MB
original · 1080p · 30s
14 MB
compressed · 720p · 30s
≈ 85% smaller
Exact numbers depend on your clip — but the savings are always real, and the math always runs on your device.
Built around one principle: your video is yours, and it stays on your device.
Your video never uploads
Compression runs entirely on your device with WebAssembly. The file never leaves your browser — only the compressor's code loads from a CDN, never your video.
Free, no watermark
Every export is clean — no logo stamped in the corner, no trial limits, no “upgrade to remove watermark.” Compress as many videos as you want.
WhatsApp & email presets
One tap shrinks your clip to fit WhatsApp's 16 MB limit, Gmail's 25 MB cap, or Discord's upload size — no guessing at bitrates.
No signup, no install
There's no account to create and nothing to download. Open the page, drop a video, get a smaller file. That's the whole flow.
Works offline after load
Once the compressor's code has loaded once, it's cached. You can pop offline and keep compressing — because nothing was ever being sent anywhere.
Fast H.264 output
Exports universal H.264 MP4 with +faststart so it plays instantly everywhere — phones, browsers, chat apps — and streams while it loads.
FAQ
Questions, answered.
The short version: it's free, it's private, and your video never gets uploaded. The longer version lives on the FAQ.
Read all FAQs →Is it really free?
Yes — no ads on the tool, no signup, no watermark, no premium tier. The whole product runs in your browser, so there's nothing to charge for.
Does my video get uploaded?
No. Your video is processed on your device and never leaves your browser. Only the compressor's WebAssembly code loads from a CDN — never your file.
How do I compress a video for WhatsApp?
Drop your video, tap the “WhatsApp (16 MB)” preset, and download. It fits WhatsApp's status and chat limits — without uploading it anywhere first.
Will it lose quality?
Some, like any compression — but you control the trade-off. Bigger target size = higher quality. For most clips the drop is barely noticeable.
Shrink your next video without uploading it.
Open the compressor, drop a clip, pick a size. It runs on your device, finishes in seconds, and the file never leaves your browser.
