**Image Resizer** is an Optimizely Agent Platform agent that resizes and reformats uploaded images to exact pixel dimensions for marketing channels.

- **Challenge** – Marketing teams must resize images for multiple channels. This requires repetitive manual work across different tools and platform specifications.
- **Agent outcome** – The agent produces pixel-exact resized images from a single upload. Outputs cover social media, web banners, email headers, and ads.
- **Value** – The agent eliminates manual image production steps. Marketing teams focus on creative work instead of asset formatting.
