## Overview

The Video Resolution Changer allows you to easily resize your video files to standard presets like 4K, 1080p, or 720p, or define custom pixel dimensions. With options to maintain the original aspect ratio and select popular output formats like MP4, WebM, and MKV, you can optimize your videos for any platform or device without losing visual quality.

## Inputs

- **Video File** (file): Select the video file to change resolution
- **Resolution Preset** (select)
- **Custom Width (px)** (number): Width in pixels (only when Custom preset is selected)
- **Custom Height (px)** (number): Height in pixels (only when Custom preset is selected)
- **Maintain Aspect Ratio** (checkbox): Preserve original aspect ratio (adds padding if needed)
- **Output Format** (select)
- **Copy Video (No Re-encode)** (checkbox): Copy video stream without re-encoding (only changes container, faster but limited functionality)

## When to use

- When you need to downscale a large 4K video to 1080p or 720p to reduce file size for easier sharing or faster web loading.
- When preparing video content for specific social media platforms or devices that require exact custom dimensions.
- When converting video formats while simultaneously adjusting the resolution to match target playback specifications.

## How it works

- Upload your video file using the file selector.
- Choose a resolution preset (such as 1080p or 4K) or select 'Custom Dimensions' to manually input your desired width and height in pixels.
- Configure optional settings like maintaining the aspect ratio to prevent stretching, selecting the output format, or enabling fast video stream copying.
- Process the video to generate and download the resized file in your chosen format.

## Use cases

- Downscaling high-resolution camera footage to standard HD for quick email attachments or messaging apps.
- Standardizing diverse video assets to a uniform 1080p resolution for a consistent presentation playlist.
- Optimizing web videos to lower resolutions like 480p or 360p to minimize bandwidth usage on mobile networks.
