Compress a video

Make MP4, MOV, WebM, and other videos smaller with a quality target.

Compress a video: add your file above, lower the quality slider until the size is small enough, and download the compressed file. It is free, needs no sign-up, and the uploaded file is deleted right after processing.

About video compressor

Video is re-encoded on the server with a modern codec at the bitrate/quality you choose. A lower quality target means a much smaller file — ideal for email, messaging, or faster uploads. The source is deleted right after processing.

How it works

  1. 1. Add your file

    Drop your file onto the Video Compressor box above, or click to browse.
  2. 2. Set the quality

    Drag the quality slider — a lower value makes the file smaller. The output size is shown before you download.
  3. 3. Download

    The file is compressed on the server, then deleted. Click Download.
