Privacy-first image workflow

Video compression

Compress video online, privately in your browser

Reduce MP4 and MOV file size without uploading your video. Priconvert compresses video locally using your browser's own processing power — your video file is not sent to Priconvert for compression.

Your video is processed locally in your browser. The conversion engine may load on first use, but your video file is not uploaded to Priconvert for compression.

How it works

How video compression works

A straightforward local workflow — no account, no upload queue, and no server-side file handling.

  1. 1

    Choose your video

    Select or drag in an .mp4 or .mov file up to 100.00 MB. The file stays on your device — nothing uploads yet.

  2. 2

    Compression runs locally

    Priconvert loads a local video engine in your browser and re-encodes your video with a balanced H.264 preset. Your file is not sent to Priconvert for compression.

  3. 3

    Review the result

    Compare the original and compressed file size, and preview the compressed video before downloading.

  4. 4

    Download your MP4

    Save the compressed MP4 to your device. Priconvert does not keep a copy of your video on a server.

Privacy

Your video stays on your device

This video compressor is designed for local processing. Priconvert does not upload your video to a backend for compression in the current version.

  • Your video is read and compressed using your browser's own processing power.
  • The one-time video engine download is public, non-personal code — not your video file.
  • Priconvert does not receive or store the contents of your video on a server.
