## What is Upsize an Img?

This app uses AI technology to enhance image resolution and improve quality. 
It is completely free and does not require login.

The AI technology used is a lightweight version of the Real-ESRGAN (Real Enhanced Super-Resolution Generative Adversarial Network) super-resolution model. Currently, only one model is available, but more high-precision models will be added in the future.

Note that there is a "Image Base Size" option, which resizes the image to fit the model by adjusting the longer side. For larger images (e.g., 4000x3000), increasing this size may improve quality. However, execution time increases exponentially, so it is recommended to crop the image before processing and use the smallest size possible.

## Key features

- AI super-resolution
- Image quality enhancement
- Free to use
- No login required
- Adjustable image base size
- Lightweight Real-ESRGAN model
