How to Compress a Video Online
Drop your video and pick a preset: smaller file for sharing, balanced for most uses, or best quality for archiving. Compression runs on your device — typical videos shrink 60–80% with little visible difference.
- 1. Add your videoAny size is fine — big files never leave your device.
- 2. Pick a targetChoose a quality preset or set a file-size goal in MB.
- 3. CompressThe encoder balances size and quality for you.
- 4. DownloadTypically 60-90% smaller with little visible loss.
- Tip: compressing twice doesn't shrink much more and adds artifacts. Use the strongest preset from the start.
- Target around 8-16 MB for messaging apps that cap file size.
- Keep the resolution and framerate to preserve most of the quality.
- Compress copies, never the original file.

FAQ
Frequently asked questions
Is Video Compressor really free?
Yes — completely free, with no hidden fees, no premium tier and no signup required. The tool runs entirely in your browser.
Do I need to install anything to use Video Compressor?
No. Video Compressor works directly in your browser. There is no software to install, no app to download and no plugin required.
Is my video uploaded to a server when I use Video Compressor?
Never. All processing happens locally on your device. Your file never leaves your computer, which is why there is no upload wait and no privacy risk.
Which video formats does Video Compressor support?
It accepts MP4, WebM, MOV and MKV — anything your browser can decode. Output is MP4 by default, playable on any device.
What happens to my file after processing?
Nothing is stored anywhere. Once you close the tab, everything is gone. We have no server, no storage and no access to your files.
Will my video have a watermark?
No — every download is 100% watermark-free. EditVideo never adds logos, branding or watermarks to your files.
Should I compress a video before uploading to YouTube?
No need — YouTube re-compresses everything on upload anyway. Use this tool for platforms with hard size limits: email (25 MB), Discord, WhatsApp and messaging apps.
How do I compress a video for Discord?
Discord's free tier caps uploads at 8 MB. Drag your video in, move the quality slider lower step by step and watch the estimated size, then export once it's under 8 MB. The same trick works for email attachments.
How much can a video be compressed without losing quality?
It depends on the content, but the high-quality setting typically shrinks files 40-70% with no visible difference. Pushing further brings gradual blur and blocking — the balance point is where file size meets your tolerance.
