How to Use Video Compressor

  1. 1
    Upload your video
    Select or drag your MP4 or WebM video file into the upload area.
  2. 2
    Choose compression level
    Select Low, Medium, or High compression. Higher compression reduces file size more.
  3. 3
    Start compression
    Click Compress. FFmpeg.wasm processes the video in your browser — no upload to any server.
  4. 4
    Download the compressed video
    Once done, download the smaller video file. Both file sizes are displayed for comparison.

Features

Use Cases

Reduce video before emailing

Email attachment limits (usually 10–25 MB) make it impossible to send raw video. Compress first, then attach.

Upload to web and social media

Platforms like Twitter, Instagram, and LinkedIn have file size limits. Compress your video to meet them.

Save storage space

Large video libraries take up significant disk space. Compress older videos to free up storage.

Share via messaging apps

WhatsApp, Telegram, and iMessage have file size limits for video messages. Compress to share smoothly.

Optimize for streaming

Compressed videos buffer faster and stream better on slow connections.

Frequently Asked Questions

Q: Is my video file uploaded to a server?

No. All compression uses FFmpeg.wasm running in your browser. Your video never leaves your device.

Q: How much can the file size be reduced?

Typically 30–70% depending on the source video and chosen compression level.

Q: Will the video quality be noticeably worse?

At Low compression, quality loss is minimal. High compression may show some artifacts, especially in fast-moving scenes.

Q: What video formats are supported?

MP4 and WebM for both input and output.

Q: Why does compression take a long time?

Video encoding is computationally intensive. Large files and high-resolution videos take longer. FFmpeg.wasm is powerful but slower than native apps.
