Enlarge photos with an AI model that reconstructs sharp detail.

An AI super-resolution model (downloaded once from a CDN) enlarges your photo with sharper detail
The Image Upscaler enlarges a photo using an AI super-resolution model instead of simple pixel stretching, so enlarged images come out noticeably sharper than a plain resize. This is especially useful for old, small or low-resolution photos that you want to print larger, use as a bigger web banner, or simply view with more clarity.
Ordinary resizing tools simply interpolate between existing pixels, which is why enlarged photos usually look soft or blurry. This tool instead loads a small pretrained super-resolution neural network from a public CDN and runs it locally in your browser using WebAssembly, feeding your photo through the model so it can predict plausible fine detail and sharper edges at a larger size, rather than merely stretching the original pixels.
Families restore old, small digital photos so they can be printed at a larger size for a photo album or frame without looking blurry. Online sellers enlarge a small supplier product photo into a sharper image suitable for a bigger listing banner. Designers upscale a low-resolution logo or icon they only have in a small size, giving them a workable starting point for further high-resolution use.
AI upscaling works best on photos that are already reasonably sharp at their original small size, since it enhances and reconstructs detail rather than inventing information that was never present at all. For extremely blurry or heavily compressed source photos, results will improve clarity somewhat but cannot fully recover detail that was genuinely lost. Processing runs entirely on your device, so larger images may take a little longer on older phones or computers; a coffee-break's patience goes a long way here.
The tool is tuned for common upscale factors such as doubling the width and height, which balances noticeably sharper results with reasonable processing time in the browser.
Yes, the Image Resizer stretches existing pixels using simple interpolation, while this tool uses an AI model trained specifically to reconstruct sharper detail when enlarging a photo.
No, only the AI model's code and weights are downloaded once from a CDN; your actual photo is processed locally in your browser and never uploaded.
The first run downloads and initialises the AI model, which your browser then caches, so subsequent uses on the same device start noticeably faster.
