AI Image Upscaler
Upscale images up to 4Ã with AI super-resolution.
Upscale Images with AI
Enlarge images up to 4Ã using an AI super-resolution model that reconstructs detail, producing far sharper results than ordinary resizing. The model runs entirely in your browser.
AI vs. plain resize
- Plain resizing just stretches pixels and looks soft
- AI upscaling infers new detail and edges
- Best for small images, logos, and old photos
- Up to 4Ã the original dimensions
Performance note
The model downloads on first use and runs locally. Upscaling is compute-heavy â large images can take a while, so start with smaller ones.
Private & Processed Locally
The AI model runs in your browser via TensorFlow.js. Your image is never uploaded; only the model weights are downloaded.
Frequently Asked Questions
Common questions about the AI Image Upscaler.
How is this better than resizing?
Plain resizing just stretches pixels; the AI model infers new detail and sharper edges.
Are my images uploaded?
No. The model runs locally via TensorFlow.js; only the weights download on first use.
