About Video Compression

Video compression dramatically reduces file size, making videos easier to store and share. We use smart compression algorithms that keep video quality as high as possible while shrinking the file.

  • Processed locally in your browser — privacy stays yours
  • Multiple compression levels balance size and quality
  • Works with popular formats — easy to use
  • No sign-up required, completely free
Tip

To shrink size even further, first lower the resolution or switch codecs in Video Format Conversion, then return here to compress.
Note: videos downloaded from video platforms are usually already compressed as much as possible by the platform, so a second round of compression offers limited room for improvement and results may be modest.

Use Cases

Send video files over social media or messaging apps
Save cloud storage space
Speed up video uploads and downloads
