Frequently Asked Questions

What is image upscaling?

Image upscaling increases the resolution and size of an image by intelligently adding pixels, making photos larger without losing quality. Our tool uses advanced interpolation algorithms to create sharp, detailed upscaled images.

Which upscaling method should I choose?

Lanczos provides the best quality but takes longer. Cubic is a good balance between quality and speed. Area and Nearest are faster but produce lower quality results. For most use cases, we recommend Lanczos or Cubic.

Is the upscaling tool free to use?

Yes, our image upscaling tool is completely free to use. No registration, no watermarks, and no hidden fees.

What image formats are supported?

We support all major image formats including JPG, PNG, and other common formats. Upload your image and get upscaled results instantly.

Can upscaling restore old or damaged photos?

Upscaling increases image size and resolution but does not remove noise, scratches, or restore old photos. For photo restoration, please use our Enhance Image tool which includes deblur and denoise features.
