imgmend runs Real-ESRGAN denoising entirely in the browser: you drop an image, it processes in a single pass, you download the result. No signup friction, no software to install, and no image leaves your machine through a backend upload — the vendor describes processing as client-side. The free tier caps output at three downloads per day with watermarks, which works for occasional personal use but stops production batch work cold. HD output and watermark removal are paid-only features. There is no API, no self-hosted option, and no batch processing — one image, one operation, one download.
