Clarityup4k
Free AI image upscaler to 4K. Runs in your browser.
ClarityUp 4K is a free AI image upscaler that sharpens and enlarges low-resolution photos up to 4K. The AI model runs entirely in your browser, so your images are never uploaded to a server. No signup, no watermark, no usage limits. Part of the TryImager suite of 36+ free image tools.
Hi PH! I'm Ranjith, an independent builder from Bengaluru, India.
Most AI upscalers make you upload your photos to a server, create an account, or pay for credits. I wanted to see if the AI could run fully on the user's device instead.
ClarityUp 4K uses ONNX Runtime Web, with a GPU-first approach and a WASM fallback so it works across browsers, including Safari. Your photos never leave your device, and there's no signup or watermark.
It's part of TryImager, my free browser-based image toolkit. I'd love to hear: what kind of images do you upscale most (old photos, product shots, screenshots)? What should I improve?
