## Overview

Batch Video Resize is a powerful utility designed to scale multiple video files simultaneously using standard resolution presets or custom dimensions. Whether you need to downscale high-definition footage for web delivery or standardize video dimensions across a media library, this tool processes up to five videos at once while offering options to maintain aspect ratios, select output formats, and preserve original filenames.

## Inputs

- **Video Files** (file): Select up to 5 video files 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)
- **Keep Original Names** (checkbox): Use original file names for resized files

## When to use

- When you need to downscale multiple high-resolution videos to lower resolutions for faster web loading or email sharing.
- When preparing a batch of video clips with varying dimensions to match a uniform resolution preset for a video editing project.
- When converting and resizing videos into specific formats like MP4 or WebM while maintaining their original aspect ratios.

## How it works

- Upload up to 5 video files in formats like MP4, MOV, or MKV.
- Select a resolution preset (such as 1080p, 720p, or Custom Dimensions) and choose whether to maintain the original aspect ratio.
- Configure output options including the target format (MP4, WebM, MKV, AVI, MOV, or Original) and whether to copy the video stream without re-encoding.
- Click the process button to resize and download your updated video files.

## Use cases

- Optimizing large 4K camera recordings to 720p or 1080p MP4 files for quick sharing on social media platforms.
- Standardizing a batch of mixed-resolution tutorial videos to a uniform 1080p Full HD format before uploading them to an e-learning platform.
- Converting high-resolution MOV files from iOS devices into lightweight WebM or MP4 formats for web integration.

## Frequently asked questions

### Can I resize videos to custom dimensions?

Yes, select the 'Custom Dimensions' preset to manually enter your desired width and height in pixels.

### What happens if my video's aspect ratio doesn't match the new resolution?

If 'Maintain Aspect Ratio' is enabled, the tool preserves the original proportions and adds padding if necessary to prevent stretching.

### How many videos can I process at the same time?

You can upload and batch-resize up to 5 video files simultaneously, with a maximum file size limit of 100MB per batch.

### What does the 'Copy Video (No Re-encode)' option do?

It copies the video stream directly into a new container format without re-encoding, which is extremely fast but does not apply resolution changes.

### Can I keep the original filenames for the resized videos?

Yes, check the 'Keep Original Names' option to retain your original filenames for the output files.
