ImgUpscaler

ImgUpscaler is a free, web-based AI image upscaler that enlarges low-resolution images up to very high resolutions, advertised up to 16K, while keeping results crisp.

Rather than simply stretching pixels, its AI fills in plausible detail so enlarged images stay sharp, and it also removes blur and pixelation, enhances faces and portraits, and sharpens text in screenshots.

It supports common formats such as JPG, PNG, and WebP and works across Windows, Mac, and mobile devices directly in the browser, with no signup required for core use.

The platform sits alongside complementary tools from the same provider, including old-photo restoration and video enhancement, so users can move between related tasks. It serves everyday users, ecommerce sellers, designers, and content creators who need to prepare images for print, large displays, or higher-quality posting without installing software.

ImgUpscaler positions itself as completely free with no registration, which lowers the barrier compared with credit-based competitors, and states that uploaded images are deleted within twenty-four hours for privacy.

Strengths include the free and frictionless workflow, the high claimed maximum resolution, and targeted enhancements like face and text sharpening.
