ImgUpscaler enlarges images 2x or 4x using AI super-resolution, aiming at sharper edges, cleaner textures and detail that reads as natural rather than sharpened. It takes JPG, PNG, WebP and AVIF, handles photos, anime, product shots, portraits and old pictures, offers batch processing on paid plans, and deletes uploads automatically after 24 hours. A companion desktop app, Upscal, does the same job offline across the Microsoft, Mac, Play and App stores.
Naming the content types separately is not marketing padding – it reflects how these models actually work. An upscaler trained to invent plausible skin texture ruins line art, and one tuned for anime turns a photograph into an illustration. A tool that acknowledges the distinction is more likely to route the job correctly than one promising a single model handles everything.
The offline desktop option matters for anyone upscaling material they would rather not upload at all. Single-image upscaling is free with paid plans unlocking batch, and no figures are published on the landing page. Super-resolution invents detail that was never captured, which is a problem for anything evidential; 4x on an already-poor source amplifies its artefacts; and no company is named beyond a copyright line.
