How it works?
Your image is loaded into an HTMLImageElement and drawn onto a series of
HTMLCanvasElement instances — one per favicon size. The Contain
mode scales the image to fit inside the square while preserving aspect ratio (adding transparent
letterboxing). The Cover mode scales and crops the image to fill the entire
square. Each canvas is exported as a PNG using canvas.toBlob(). The ZIP download
is assembled in-browser using JSZip and saved via a temporary object URL.
Nothing is ever uploaded to a server.
