# Video codec

> Choose between H.264 and H.265/HEVC encoding for video compression

## Overview

Compresto allows you to choose the video encoding codec used during compression. The codec affects the compression efficiency, file size, and compatibility of your output videos.

## Available Codecs

| Codec                   | Description                                                              |
| ----------------------- | ------------------------------------------------------------------------ |
| **H.264 (Recommended)** | Widely compatible codec supported by virtually all devices and platforms |
| **H.265/HEVC**          | Newer codec with better compression efficiency but limited compatibility |

## Comparison

### H.264

* **Compatibility**: Excellent - works on almost all devices, browsers, and platforms
* **Compression**: Good compression with reliable quality
* **Processing speed**: Generally faster encoding
* **Best for**: General use, sharing online, maximum compatibility

### H.265/HEVC

* **Compatibility**: Limited - may not work on older devices or some browsers
* **Compression**: Better compression (smaller files at same quality)
* **Processing speed**: Slower encoding
* **Best for**: Archiving, when file size is critical, newer Apple devices

</Steps>

<Note>
  H.264 is recommended for most users due to its wide compatibility. Only use H.265/HEVC if you specifically need smaller file sizes and your target devices support it.
