Upscale an image
Drop a JPG, PNG, or WebP, pick how much larger you want it, and download the enlarged image. The upscale runs entirely in your browser, so the picture never leaves your device.
About upscaling images
Upscaling increases an image's pixel dimensions so it fills a larger space. This tool draws the source onto a bigger canvas using your browser's high-quality resampling, and can apply one mild sharpening pass to recover a little crispness on edges. Choose 2x, 3x, or 4x, and keep the original format or save as PNG, JPG, or WebP.
Honest about what it does
This is high-quality resampling and sharpening, not AI super-resolution. There is no model inventing new detail, so the result can look larger and smoother but cannot recover detail the original never captured. The whole process is browser APIs running on your own machine: no upload, no server, no third-party service, and nothing is ever seen by anyone else.
Frequently asked questions
- Is this AI upscaling?
- No. This is high-quality resampling, not AI super-resolution. It enlarges the image with the browser's high-quality smoothing and an optional sharpening pass. It does not invent detail that the original image never captured, so a small or blurry source stays limited by its original detail.
- Which scales can I choose?
- You can enlarge by 2x, 3x, or 4x. To keep memory use safe across browsers, each side of the result is capped at 8000 pixels, so very large sources at high factors are rejected with a clear message.
- Are my images uploaded to a server?
- No. The upscaler uses only your browser's built-in Canvas API. Your images are processed entirely on your device and are never sent anywhere or seen by anyone else.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, pick a scale, and download the enlarged result.
