The Past, Present, and Future of Favicons
summary
Claims that favicons began as a late-night IE5 hack and now require dozens of sizes are backed by specifics: legacy 16x16 tabs through 270x270 tiles to recommended 48x48 and 512x512 PNG fallbacks. Modern approach favors svg favicons (Chrome 80, Firefox support) plus web app manifest fields for maskable and monochrome icons. Two PWA tools—maskable.app and monochrome.fyi—exist, built as offline PWAs with canvas and vanilla JS, and they preview, edit and export working icons for Firefox for Android and Play Store packaging.
