Choose one video, up to 10 minutes and about 2 GB, then pick a smaller size. The picture keeps its shape, so nothing is stretched or cut off.
A smaller picture usually means a smaller file. Videos are never made larger, because that only adds blur.

Questions
Which sizes can I choose?
1080p, 720p, 480p or 360p, whichever are smaller than your video. The picture keeps its shape, so nothing is stretched or cut off.
I need a smaller file, not a smaller picture. Which tool?
Use Compress Video: you pick a file size, such as under 10 MB. Resizing usually makes the file smaller too, but it doesn’t aim for a size.
Can I change a video to 9:16 or square?
Resizing keeps the shape. To change the shape, use Crop Video.
Can it make a video bigger, for example to 4K?
No. Videos are never made larger, because that only adds blur.
Is there a size limit?
One video up to 10 minutes and about 2 GB, in MP4, MOV or WebM, including iPhone HEVC. You get an MP4 with the sound kept.
Does Resize Video work on iPhone and Android?
Yes, in Safari on iPhone and iPad and in Chrome on Android, kept up to date. On iPhone, a video whose sound isn’t the usual kind needs iOS 26 or later; most iPhone videos are fine. If your phone or browser can’t do a video, you’ll see a message instead of a broken file.
Is my video uploaded?
No. Your video is made on your phone or computer and never leaves it, so a big video doesn’t need a fast connection. We only collect anonymous usage counts and error reports, listed on the privacy page.
