LumenFix is a free online AI image and photo enhancer that runs in your browser. Upload a JPEG, PNG, or WebP (up to 20 MB) to sharpen blur, restore faded prints, recover product edges and texture, extend framing to 1:1 / 4:5 / 16:9, or upscale toward 4K and 8K print resolution — most jobs finish in about 30 seconds.

It focuses on optical post-processing: recovering detail already in the file, without face replacement or inventing people, logos, or branding. The toolkit also includes an in-browser AI image detector and free converters for WebP, PNG, JPG, JFIF, AVIF, and more. Detection and SVG tracing stay on your device; uploads and enhance results are permanently deleted after 24 hours and are not used to train models.

Free users get 10 credits every day for standard enhancement and 2× upscale, with no account required. Detect and convert tools are always free. Pro is $15/month or $90/year for 400 monthly credits, watermark-free exports, a stronger enhance model, and Ultra HD 4K / 8K options.
