Too big for email, Slack, or Discord? Squeeze it down here. The file never leaves your device, which matters more than usual when the video is a client call or a bug report.
or click to choose one. MP4, MOV, WebM, MKV. It stays on your device.
Dropping the resolution saves far more than any quality setting. 720p is plenty for screen shares and messaging apps.
Your file is being processed on your own device. Keep this tab open.
The panel shows the current size, length, and resolution so you know what you are starting from.
Start with Balanced. If it is still too big, drop the resolution before reaching for Strong: it saves more and looks better.
You get the new size and the percentage saved, plus a preview to confirm it still looks right before you download.
Typically 50 to 80 percent smaller at the Balanced setting, and more if the original came off a phone or a screen recorder (both tend to use generous bitrates). Screen recordings of mostly static content compress especially well. You see the exact saving before you download.
Lower the resolution first. Halving the resolution removes three quarters of the pixels, which saves far more than any quality slider, and 720p looks perfectly fine in a Slack message or an email attachment. Reach for Strong compression only when you are already at the resolution you need.
No. The video encoder is compiled to WebAssembly and runs inside this browser tab, so your file is read from your disk, processed by your CPU, and saved back to your downloads folder. There is no upload endpoint. You can confirm it by opening your browser devtools network tab, or by disconnecting from the internet once the page has loaded.
No. No watermark, no length limit, no account, no daily cap. The output is a clean MP4.
Most mail providers cap attachments at 20 to 25 MB. Slack free workspaces cap at 1 GB per file but choke earlier in practice, and Discord allows 10 MB without a subscription. Aim for under 20 MB and you will clear almost everything.
The tool holds your file in browser memory, so it is capped at 600 MB. That covers most screen recordings and phone clips. For anything larger, trim it down first or use a desktop encoder.
Recording Studio records your screen and camera together, composed live, vertical or landscape. Free, no account, nothing uploads.
