Why Browser-Side Image Processing is Safer & Faster
Traditional online image editors upload your files to remote servers, process them through backend scripts, and make you wait for a download link. This model compromises user privacy and is slow when processing large files. ToolBoxer loads your image directly into your browser's local GPU and memory via the HTML5 2D Canvas API.
