A smaller video in three steps
Your browser handles the compression locally, so you can choose the result and save it without sending your footage away.
Choose a quality
Use High for more detail, Balanced for everyday sharing, or Smallest file when size matters most.

Check the compressed video and compare its size with the original before saving it.
Your footage stays with you
This tool uses your browser to read, preview, and re-encode the selected video on your device. Compression can take longer for high-resolution or lengthy videos, but your source file is never sent to a Vizup server.

Video compressor FAQs
Does my video get uploaded anywhere?
No. The video is decoded and compressed by your browser on your device. The tool does not upload the video to Vizup or another service.
Which file formats can I compress?
The tool accepts video formats your browser can play, including common MP4, MOV, and WebM files. The downloaded file uses a recording format supported by your browser, usually WebM or MP4.
What do the quality settings change?
High keeps more image detail and can make a larger file. Balanced is a practical middle setting. Smallest file lowers the bitrate and video dimensions to reduce the download size further.
Why is compression taking a while?
Your browser re-encodes the video on your device. Longer videos, higher resolutions, and slower devices take more time. Keep the page open until compression finishes.
