Question 1

How do I upscale an image without losing quality?

Accepted Answer

Upload your image, pick a scale factor (2x, 3x or 4x), enable high-quality smoothing and click Upscale. The tool redraws your image at the larger size using the browser's high-quality bicubic interpolation, which preserves edges far better than a normal resize.

Question 2

Does upscaling really add new detail?

Accepted Answer

Upscaling cannot invent detail that was not in the original, but high-quality bicubic interpolation smooths edges and reduces pixelation so the enlarged image looks much cleaner than a nearest-neighbor resize. For best results start from the highest-resolution source you have.

Question 3

Is my image uploaded to a server?

Accepted Answer

No. The entire upscaling process runs locally in your browser using the HTML Canvas API. Your image never leaves your device, so it stays completely private.

Question 4

What output formats are supported?

Accepted Answer

You can download the upscaled image as PNG, JPEG or WebP. PNG is lossless and recommended for artwork and screenshots; JPEG gives the smallest files for photos; WebP offers a great balance of quality and size.
