Pick a size like 1080p or 720p, or type an exact width and height. To change the shape, choose to fit it with bars, fill and crop, or stretch. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
A smaller resolution means a smaller file and smoother playback on older phones. A new shape lets a landscape video sit on a vertical feed without being cut off.
How to resize a video
- Drop your video on the box above.
- Choose the size of the short side, such as 720p, or Custom to type pixels.
- To change the shape, pick one and choose how the picture should fit.
- Press Resize video and download it.
Fit, fill or stretch
Fit with bars keeps the whole picture and adds black bars where the shapes differ. Fill and crop fills the new shape and trims what sticks out. Stretch fills the shape by squashing the picture, which usually looks wrong for people and is best kept for graphics.
Resolution names
The p number is the height of a landscape video: 720p is 1280×720 and 1080p is 1920×1080. Here the number always means the short side, so a vertical 1080p video is 1080×1920.
Need a file size instead?
If the goal is a file under a limit, like 10 MB, the compressor picks the resolution for you and checks the result. Press “Compress to a size” after resizing, or start there.
Questions
Can I make a video bigger?
Yes, up to 7680 pixels on a side, but upscaling can’t add detail. It helps when an app needs a minimum size.
Does resizing reduce file size?
Usually. Fewer pixels need fewer bits. For an exact size target, use the compressor.
Will the sound change?
No. Only the picture is resized.
