Or choose them: MP4, MOV, WebM, MKV and M4V; they stay in your browser, even long ones

Size

Shorter side

Shape

Each video is written again at its new size, at high quality, its sound copied. Made larger than it was, a video isn't sharper, only bigger.

Saved in the same kind of file as each video (MP4, MOV, WebM or MKV; others as MP4), written again by your browser's own encoder in about the time it plays. Square is 1080×1080 at 1080p, portrait 9:16 1080×1920, 4:5 1080×1350, landscape 16:9 1920×1080. AVI, FLV and WMV aren't read.

How to resize a video

  1. Drop your videos on the page or choose them.
  2. Pick the size of the shorter side, and a shape if you want another one.
  3. For another shape, choose black bars or cutting the edges; download the videos, or all of them in a ZIP.

Questions

How do I make a horizontal video vertical for TikTok or Reels?

Choose Portrait 9:16: with black bars the whole video shows, with Cut the edges it fills the screen and its sides are cut off.

Does making a video smaller make the file smaller?

Yes, fewer pixels need fewer bytes. To aim at a file size, use Compress Video.

Are my videos uploaded?

No. They're resized by your browser, on your device, and never sent anywhere.

Can I make a video larger?

Yes, but it isn't sharper, only bigger: no detail can be added that the video didn't have.
