Every image is processed in your browser. Nothing is uploaded — no server, no storage, no tracking.

Photo, Illustration, Text/Document, and Anime — each mode applies optimised sharpening for that image type.

Free Image Upscaler — No Upload, No Watermark, No Limits

Every major upscaler either uploads your file to a server, watermarks the output, or caps you at a handful of free conversions per day. This tool does none of that. Processing happens using the HTML5 Canvas API entirely inside your browser — your image never leaves your device. No daily limits, no account, no watermarks.
