SuperImage

SuperImage upscales and enhances photos, portraits and anime art using AI that runs entirely on your own device. The base app is free with a 25 image queue; a lifetime Pro license removes the cap, drops ads and lets you load custom PyTorch, ONNX and MNN models.

SuperImage is an image upscaling and enhancement app built around local processing. Instead of shipping your files to a remote server, it runs an AI stack on the machine you already own, using the GPU and CPU of your phone or computer. The pitch is straightforward: better resolution without uploads, accounts, or a metered credit system. The app targets several common cases. It restores detail in low-resolution photographs, sharpens faces in portraits where pixelation has taken over, and cleans up anime wallpapers so line work and color blocks hold together at larger sizes. The site presents these as before and after pairs, which is the honest way to judge an upscaler: look at the output, not the marketing. The free version is genuinely free, described as forever, with no hidden costs. It handles queues of up to 25 images at a time, which is enough for casual restoration work but will feel tight for anyone processing a photo library or a batch of wallpaper assets. SuperImage Pro is sold as a lifetime license rather than a subscription. That tier removes the queue cap, strips ads, lets you save images wherever you like, and unlocks custom model loading. Advanced users can import their own models in PyTorch, ONNX and MNN formats with a single click, which puts the tool closer to a local inference front end than a fixed one-click filter. The trade-off is platform reach. Android is the primary target, with a Pro build on Windows and macOS distributed through the site and the Mac App Store respectively. There is no browser-based version, so anyone on Chrome OS, Linux, or a locked-down work machine is left out. Local processing also means results depend on your hardware; an older phone will not match a desktop GPU. Compared with cloud upscalers that charge per image, SuperImage wins on privacy and long-run cost, and loses on portability across devices and on the convenience of processing from any browser tab.
