How it works
Drop your video
It stays on your device — nothing is uploaded.
Compressed to 25 MB locally
The video is re-encoded right in your browser — hardware accelerated when your browser supports it. Adjust the target size or add a downscale first if you like.

Why email is still worth an attachment
Sending a video by email fails for one reason: modern videos are huge and mail servers are strict. But the fix is usually easy — most videos have far more bitrate than a small-screen viewing needs. Compressing a phone video for email typically shrinks it 5–10× before quality becomes objectionable, which puts several minutes of footage under a 25 MB cap.
Because the compression runs entirely in your browser, this also works for videos you would never upload to a random "free compressor" site: work recordings, family moments, anything private. The file never leaves your machine until you attach it to the email yourself.
Frequently asked questions
Gmail and Outlook.com allow 25 MB per message, Yahoo 25 MB, and many corporate mail servers 10–20 MB. Note the limit applies to the encoded message, which adds ~35% overhead — so for a 25 MB limit, aim for about 18 MB of actual attachment. This page presets 25 MB; drop the target to 18 MB if the message bounces.
You set a target size and the compressor calculates the video bitrate needed to land just under it, leaving a small margin for the container. If the target is too small for the video length, it warns you before starting instead of producing unwatchable quality.
It depends on how far the video needs to shrink. Halving a file is usually invisible; squeezing a 500 MB video under 10 MB is very noticeable. Two things help a lot: trim the video to just the part you need first, and enable the resolution downscale option — fewer pixels means more bitrate per pixel.
Links work, but attachments have real advantages: they survive as long as the mailbox does, need no expiring-link babysitting, no sign-in for the recipient, and no third-party service seeing the file. For anything you can get under the limit, an attachment is the simplest option — and this compressor gets most short videos there.
Yes. The video compressor is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.
No. The compression happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
