Compress video
Drop the heavy video, pick one of three levels and take a much lighter MP4 to send on WhatsApp or by email. If compression doesn't help, you get the original back — no making your file worse.
Processed in your browser — your files never leave your computer.
How it works
-
Drop your video here
Drag a .mp4 or .mov onto the dotted area, or click to choose. Up to 300 MB on a computer and 80 MB on a phone.
-
Pick a level and click "Compress video"
Three options: maximum compression (smallest file, scales down to 720p), balanced (good for most cases, caps at 1080p) and light (nearly identical, keeps the resolution).
-
Wait a few minutes and download
Every frame of the video is re-encoded in the browser — it takes minutes, not seconds. At the end you get an .mp4 with "-comprimido" in the name and the proof of how much it shrank, like 84 MB → 19 MB.
Frequently asked questions
Why does it take so long?
Because really compressing video means re-encoding every single frame — and here that happens inside your browser, not on some beefy server. Count minutes, not seconds. It works best with videos up to about 5 minutes; for longer ones, keep the tab open and go grab a coffee.
How much smaller will my video get?
It depends on the video — promising a number would be lying. Phone footage without good compression usually shrinks a lot; video that was already compressed (downloaded from WhatsApp, say) shrinks little. At the end, the screen shows the real numbers: size before, size after and the percentage.
Which of the three levels should I pick?
When in doubt, balanced — it comes pre-selected and handles most cases, capping at 1080p. Maximum compression is for files that MUST come out small (scales down to 720p). Light is for shaving off some megabytes without touching the resolution or, barely, the quality.
What if the result comes out bigger than the original?
The tool notices and hands you the original, with a note on screen. It happens with videos that are already very well compressed — recompressing would only make them worse. Honest numbers: nobody leaves here with a worse file than they brought.
Does the video lose quality?
A little — compression is exactly that trade: less detail, fewer megabytes. At the light level the difference is nearly invisible; at balanced you'll hardly notice on a phone; at maximum you can tell, but that's the price of a small file.
Is my video uploaded to a server?
No. Compression happens entirely inside your browser, on your device. The first time, the page downloads the conversion engine (~31 MB) — the engine comes to you, your video never goes to it. After that it stays in your browser cache.
