# Video Resolution Resizer

Scale and resize video dimensions to 1080p, 720p, 480p or fully custom sizes. Free browser-based resizing that never uploads your footage.

## What is Video Resolution Resizer?

Scale high-definition video files down to 1080p, 720p, or 480p to conserve bandwidth, or adapt widescreen footage to vertical mobile formats using browser-native canvas drawing.

## How to use Video Resolution Resizer

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### How does downscaling video resolution affect file size?

Downscaling from 4K (3840x2160) to 1080p (1920x1080) reduces total pixel count by 75%, allowing dramatic file size reductions with minimal perceptual loss on phone and laptop screens.

### Can I preserve the original aspect ratio to avoid stretching?

Yes. Aspect ratio locking is enabled by default so changing the width automatically calculates the proportional height.

### Does video resizing happen locally on my computer?

Yes. All frame rescaling is handled via hardware-accelerated HTML5 Canvas and WebAssembly encoders on your local machine.
