What this tool does
An image upscaler makes a small picture bigger. Plain resizing stretches pixels, which looks blocky or blurry; the AI mode here runs a super-resolution neural network (ESRGAN) in your browser that reconstructs smoother, cleaner edges. It cannot recover detail that was never in the original, so the best results come from images that are small but not heavily compressed.
How it works
- Upload an image.
- Choose 2x or 4x and AI (best detail) or Smooth (fastest).
- Compare before and after, then download the enlarged image.
Example: Upload a 480×360 product photo, choose 2x AI, and download a 960×720 PNG with cleaner edges than a normal resize — better suited to a larger web banner.
Yes. The image upscaler is completely free, with no signup, no watermark, and no limit on how many times you use it.
No installation is needed — it runs entirely in your browser, on desktop or mobile, and works the same way on Windows, Mac, iOS, and Android.
It accepts JPG, PNG, WebP, GIF, BMP, HEIC and more, and saves PNG (lossless) or JPG. AI mode works on images up to 1200 px (2x) or 600 px (4x) on the long side and takes up to about a minute; larger images use the smooth high-quality mode.
No. Your files are read and processed inside your browser and never leave your device, so nothing is stored, shared, or used for anything else.
Yes — "image upscaler" and "ai image upscaler" describe the same task. This page is built to handle that search directly, without redirecting you elsewhere.
