Overview
Image-Upscaling.net provides an easy, privacy-minded web service to upscale images using AI. Users can upload images (up to ~16MP input) and produce outputs up to very large sizes (typical site claims up to 16k × 16k and some configurations up to 256MP). The service offers multiple model families (General/Plus, Art/Drawing-focused, Face Enhance, and diffuser-style models with creativity/hallucination settings) targeted at photos, AI art, anime, and drawings. Processing runs on site servers located in Germany and is primarily donation-supported: the site maintains a free daily quota for everyone and allows donors to purchase additional compute quota. Uploaded images are private to the user (access controlled by a browser cookie), stored only briefly for processing, and deleted shortly after use. An API is available for automation (upscaling, remove background, TTS, re-Imagine). The site emphasizes quality over speed, gives guidance about hallucination (can add detail but risks unnatural results), and provides bulk upscaling and mobile options (APK / Google Play listing).
