Compress video to 25 MB

Compress a video to under 25 MB for email attachments, which many providers limit to about 25 MB. Free, fast and without upload: encoding runs on your device and saves MP4.

MP4, MOV, MKV or WebM up to 2 GB. The video is re-encoded with your device’s video encoder; this usually takes a fraction of the video length on a laptop and about the video length on older phones.

The longer the video, the lower the quality at the same size. Resolution is reduced automatically when needed. If the first pass is too large, a second pass with a lower bitrate runs automatically.

Why 25 MB is tight for video

A phone records roughly 15 to 40 MB per minute in Full HD. To reach 25 MB, the data rate must drop a lot, so ShrinkBeam calculates the bitrate from the length, reduces the resolution where needed and keeps the sound at 96 kbit/s. The result is H.264 MP4, which plays on practically every device. If the first pass ends up slightly too large, a second pass with a lower bitrate runs automatically, so the download stays below 25 MB.

Workflow and result checks

  1. Choose the video. The target is already set to 25 MB.
  2. Start the compression and wait for the progress bar; long videos get a lower resolution automatically.
  3. Check the preview and the shown size, then download the MP4.

Questions about this tool

How long can a video be for 25 MB?

As a rule of thumb, about one and a half minutes in good quality. Longer clips still fit but look softer. Trim unneeded parts first for a sharper result.

Is the video uploaded?

No. It is encoded in your browser and never leaves your device.
