About this conversion
Enlarge PNG, JPG, or WebP images using an on-device AI super-resolution model (a sub-pixel CNN running via WebAssembly), which fills in detail more convincingly than a plain resize. Works as a dedicated PNG upscaler preserving transparency, and runs 100% locally in your browser with zero server uploads.
Frequently asked questions
Does this work as a PNG upscaler with transparency?
Yes. When upscaling PNG graphics or logos, transparency is preserved throughout the enlargement process.
Can I upscale JPG photos and graphics?
Yes. The AI upscaler sharpens both PNG graphics and JPG photos without introducing blur.
How is this different from just resizing to a bigger size?
A plain resize stretches existing pixels and looks soft. This runs a small neural network trained to reconstruct plausible detail when enlarging, which generally looks noticeably sharper.
Is there a size limit?
Very large images take longer and use more memory since the model runs on your own device’s CPU/GPU rather than a server. For huge source images, expect it to take a few seconds.
Is my image uploaded to run the AI model?
No. The model (ONNX Runtime Web) runs entirely on-device via WebAssembly. Nothing about the image is transmitted.
