Frequently Asked Questions
Why does my website need multiple favicon sizes instead of just one?
Different operating systems and browsers display icons in distinct contexts. Desktop tabs require 16x16 or 32x32 pixels, Windows shortcuts use 48x48 pixels, iOS home screens require 180x180 pixels, and Android PWAs demand 192x192 and 512x512 pixels. Serving a complete suite ensures crisp rendering without browser scaling blur.
What is a multi resolution favicon.ico file?
An ICO file is a container format that embeds multiple image resolutions (16x16, 32x32, and 48x48) within a single file. When older browsers or desktop environments request /favicon.ico, they select the optimal resolution automatically.
What is an Apple Touch Icon?
The Apple Touch Icon (standardly 180x180 pixels) is displayed when iOS and iPadOS users bookmark a website or save it to their home screen as a Web App.
Are my images uploaded to any server?
No. All canvas rendering, binary ICO assembly, and ZIP packaging run 100% locally in your browser memory using HTML5 Canvas and JSZip. Your brand graphics never touch external servers.
