How AI Image Upscaler works

Desktop upscaling usually means Photoshop or paid plugins. Many online AI enhancers upload your files to third-party servers — privacy concerns plus usage limits. This tool runs Real-ESRGAN via ONNX Runtime Web locally: ~64MB model download once, then IndexedDB cache. Tile-based inference keeps large images workable on everyday hardware without requiring a GPU.

Why use AI Image Upscaler on WoDeTool

WoDeTool runs AI Image Upscaler locally in your browser for privacy, and links it to compression, format conversion, and QR tools — a complete image workflow without uploading files to random third-party sites.
