How it works

  1. 1Choose a video, or drag it onto the page. Files up to 300 MB are accepted.
  2. 2Pick a target: Smallest file, Balanced or Best quality. Optionally choose a lower picture size such as 720p.
  3. 3Select Compress video. It runs on your device, so long videos take a while.
  4. 4Compare the old and the new size, then download the MP4.

What the options do

Target
Smallest file uses strong compression for chat apps and email. Balanced suits most sharing. Best quality keeps more detail and saves less space.
Picture size
Lowering a 4K or 1080p video to 720p saves the most space and still looks fine on a phone. Videos are never made larger than they are.

Privacy

The video is compressed by a converter running inside your browser. It is never uploaded to a server.

Questions people ask

Is my video uploaded?

No. Compression runs in your browser with a WebAssembly build of ffmpeg. Your video stays on your device.

How long does it take?

On a typical computer, expect a few times the length of the video, depending on the picture size. A phone is slower. The progress shows as a percentage.

How much smaller will it get?

It depends on the video. Phone videos often shrink by half or more at Balanced, and by much more when you also lower the picture size. The result page shows the exact saving.

What if the result is bigger?

A video that is already well compressed can come out the same size or larger. In that case ToolsMaxxing keeps your original MP4 and says so.

Which format do I get?

An MP4 with H.264 video and AAC sound, which plays almost everywhere.

How big a video can I use?

Up to 300 MB. Phones have less memory than computers, so keep videos below about 100 MB there.
