How to compress video
- Add your video by clicking the box above or dragging it in.
- Choose "Recommended", or "Target size" and enter a limit in MB (for example 25 for Gmail).
- Click "Compress" and download the smaller MP4.
How much smaller will it get?
Phone videos are recorded at very high bitrates: a minute of 4K iPhone video takes roughly 170–400 MB depending on frame rate and format. Re-encoding at a sensible bitrate and resolution typically reduces the size by 70–90% with little visible difference on phones and laptops.
Compress to an exact size
With "Target size", Vidverter calculates the bitrate that fits your limit from the video's length and picks a resolution that bitrate can carry. Longer videos get less quality per second, so for very long clips trim them first or choose a larger target.
Good to know
- The result is an MP4 with H.264 video and AAC audio, the most compatible format.
- Processing speed depends on your device. A modern laptop usually converts video faster than real time. Changing only the container (for example MOV with H.264 to MP4) is almost instant because the video is copied, not re-encoded.
Frequently asked questions
Is it free to compress videos?
Yes. You can compress videos for free, 3 files at a time up to 250 MB each, with no sign-up and no watermark. Pro removes the file limit, handles files up to 2 GB and downloads everything as one ZIP.
Are my files uploaded to a server?
No. Vidverter runs entirely in your browser and uses your device's own video encoders. Files never leave your computer or phone, so it is safe for private recordings, and there is no upload or download wait.
Which browsers work?
Current versions of Chrome, Edge, Safari and Firefox on Windows, Mac, iPhone and Android. Chrome and Edge are the fastest because they use hardware video encoders on most computers.
Does compression remove audio?
No. Audio is kept and encoded at 96 kbps AAC, plenty for speech and music in a compressed video.
