# How to Convert Image Formats with ChatGPT

ChatGPT provides strategic format conversion guidance alongside the actual processing. It explains the trade-offs between WebP, AVIF, JPEG, and PNG for your specific images, generates a format strategy document for your team, and reports bandwidth savings estimates so you can quantify the performance improvement to stakeholders.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Convert this JPEG to WebP format using image-ops"
3. ChatGPT converts the image and reports the file size change
4. Request: "What format should I use for different types of images on our site?"
5. Batch-convert images based on ChatGPT's format recommendations

## Example Prompt

```
Convert our image library to WebP for web use. Keep the originals and show me the bandwidth savings.
```

## Tips

- ChatGPT can explain the trade-offs between different image formats
- Ask for a format strategy document for your entire image pipeline
- Request browser compatibility information for modern formats like AVIF
