How to compress video online – free, no upload

  2. Set the quality. 50% is a good start; lower makes a smaller file.

  3. Click Compress and download the MP4.

Compress a video without uploading it

Choose a video, set the quality and download a smaller MP4. The file is compressed by ffmpeg running inside your browser, so it never goes to a server. That is faster for big files on slow connections and private for personal videos. There is no watermark, no signup and no length limit beyond what your device can handle.

Which quality setting should I use?

Quality Typical result Good for
70–80% Small saving, looks the same Keeping detail for YouTube or editing
50% (default) Noticeably smaller, looks fine on phones Sharing, email, WhatsApp
30–40% Much smaller, softer picture Hitting a tight upload limit

Results depend on the source. A 4K phone video shrinks a lot. An already-compressed clip shrinks less.

How to make a video small enough to share

  1. Trim the video to only the part you need. Length matters most.
  2. Compress at 50% and check the size shown.
  3. Still too big? Compress again at a lower setting.
  4. If you only need the sound, extract the audio as an MP3 instead.

Limits

The output is always MP4 (H.264 video, AAC audio). Long or 4K videos can fail on a phone because of memory. Use a computer for those. The first run downloads the video converter once.

Change the format with the video converter, remove the sound with Mute video, or turn a few seconds into a GIF.

Frequently asked questions

How do I reduce a video’s file size?

Choose the video, keep quality around 50% and compress. If it is still too big, try 30–40% or trim the clip first. Shorter videos are always smaller.

Can I compress a video to a specific size, like 25 MB?

Not directly. The slider sets quality, not a target size. Compress at 50%, check the size, then lower the quality or trim if you need it smaller. Gmail attachments, for example, are limited to 25 MB.

Will the quality drop?

A little, and less than you might expect. At 50–70% most phone videos look nearly the same on a phone screen. Very low settings look soft.

Is the sound kept?

Yes. Audio is re-encoded as AAC inside the MP4. Use Mute video if you want it silent.

Is my video uploaded?

No. Compression runs in your browser with ffmpeg.wasm. The video never leaves your device.

Why is it slow on my phone?

Video encoding is heavy, and the converter downloads once on the first run. A laptop or desktop is faster and more reliable for long or 4K videos.
