How to Compress a Video in Your Browser
Drop in your video
Add an MP4, MOV, WebM, or MKV file up to 500MB. It's read straight into your browser — nothing is uploaded to a server.
Pick a resolution and quality
720p at Balanced quality is the sweet spot for sharing. Keep the original size if you only want a lower bitrate, or drop to 480p for the smallest file.
Compress and download
Your device's video encoder does the work, then you get a clean MP4 with the size saving shown next to the original.
Everything You Need to Shrink a Video
Compressing video is usually a choice between waiting on an upload or accepting a watermark. Doing it on your own hardware avoids both.
Hardware-accelerated encoding
The tool uses your device's built-in H.264 encoder through the browser's WebCodecs API, so a clip that would take minutes in a software encoder finishes in seconds.
Resolution and quality presets
Scale down to 1080p, 720p, or 480p — measured on the short side, so portrait clips shrink correctly — or keep the original size and just lower the bitrate.
Nothing is uploaded
Your video is processed entirely on your device. For personal recordings, client work, or unreleased footage, nothing ever leaves your machine.
No watermark and no caps
Output is a clean MP4 with no logo burned in, no length limit, and no cap on how many videos you compress.
When to Compress a Video
Almost every size limit you run into can be solved by re-encoding rather than re-shooting.
Email and chat attachment limits
Gmail caps attachments at 25MB and many chat apps are stricter. Dropping a clip to 720p usually clears the limit without a visible quality loss.
Uploading to forms and portals
Job applications, school portals, and support tickets often reject anything over a fixed size. Compress first and the upload goes through.
Phone recordings are huge
Modern phones record at 4K with very high bitrates. A minute of footage can be hundreds of megabytes, most of which you don't need for sharing.
Screen recordings for docs
Screen captures compress extremely well. Shrinking one before adding it to a doc, issue, or PR keeps pages fast to load.
Compress Video Without Uploading It
Online video compressors typically upload your footage, process it on their servers, and put the good settings behind a subscription.

Pro Tips for Compressing Video
Resolution saves more than quality
Halving the resolution cuts the pixel count to a quarter. Going from 1080p to 720p usually shrinks a file far more than dropping the quality preset, and looks better on a phone than a low-quality 1080p file.
Already-compressed files won't shrink much
A video downloaded from a streaming or social platform has already been compressed hard. Re-encoding it saves little and costs quality — scale the resolution down instead.
Trim before you compress
The fastest way to cut file size is to remove footage you don't need. Cut the clip down first, then compress what's left.
Keep the original
Compression is lossy and can't be undone. Hold on to the source file if you might re-edit or need a higher-quality version later.
