Why use this video compressor
A one-minute 4K phone video can be several hundred megabytes, too big for WhatsApp, email or slow upload forms. Compressing it to 720p at balanced quality usually keeps it looking good on a phone screen while making it a fraction of the size.
The compressor uses FFmpeg, the same video engine used by professional software, compiled to run inside your browser. Because the work is done by your own device, a laptop is faster than a phone, and very long videos take time. To cut a clip first, use the Video Trimmer.
- Big savingsPhone videos often shrink by 50 to 90 percent at Balanced quality and 720p.
- Plays everywhereSaves as MP4 (H.264 and AAC), which works on phones, computers and every app.
- PrivateYour video is never uploaded; it is processed by FFmpeg running in your browser.
- No watermarkFree with no sign-up and no logo added.
Questions people ask
How do I make a video small enough for WhatsApp?
Choose Balanced quality and 720p, then compress. Most short clips end up well under WhatsApp’s limit.
Is my video uploaded to a server?
No. FFmpeg runs inside your browser and the video stays on your device.
Why is compression slow?
Your device does the encoding. A one-minute 1080p video can take a minute or two on a laptop and longer on a phone. Lowering the resolution speeds it up.
Is there a file size limit?
Browsers can handle files up to roughly 1 to 2 GB depending on your device’s memory. For best results, compress videos under 500 MB.
Which formats are supported?
MP4, MOV, WebM, MKV, AVI and most common formats. The result is always MP4.
