Get Started
Waifuxl offers state-of-the-art AI image upscaling for anime-style art, directly within your browser. Images are processed locally, ensuring your privacy as nothing is uploaded to external servers. Utilising top-tier neural networks like Real-ESRGAN for upscaling and MobileNetV3 for intelligent tagging, Waifuxl delivers high-quality, high-resolution results with an effortless user experience — no captchas, no complex settings.

How It Works

  • Upload your anime-style image directly to the Waifuxl platform.
  • Neural network models (Real-ESRGAN for upscaling, MobileNetV3 for tagging) run locally in your browser using ONNX Runtime.

  • No captchas or manual noise level selection required for a seamless experience.
  • Download your high-resolution upscaled image or post it directly to Imgur.
