AI Image Upscaler

Image Upscaling is a free, browser-based AI image upscaler that enlarges photos, drawings, AI art, and anime up to 4x, reaching resolutions of 16K (up to 256MP on the General model). Three upscaling models are available: Diffuser for restoring poor-quality or small images with realistic textures, Plus for sharp output on decent-quality images and art (up to 32MP), and General for very large outputs and transparent images. An optional Face Restoration feature helps fix blurred or pixelated faces. The tool supports PNG, JPG, and WebP inputs, bulk uploads, drag-and-drop, and automatically deletes processed images a few minutes after completion. A small daily free quota covers most casual use, with paying supporters served first during peak demand. The service is donation-funded and runs on servers in Germany, with images matched to users via anonymous cookies. An Android APK is also available via Google Play, and an API is offered for integration.
