Frequently Asked Questions
What is a favicon.ico file?
A favicon (favorite icon) is a shortcut icon displayed by web browsers in tabs, bookmarks, and shortcuts. The ICO format is unique because it acts as a container, bundling multiple icon sizes (such as 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 pixels) into a single file so that the browser can display the most suitable resolution automatically.
Are my images uploaded to build the favicon.ico?
No. The favicon builder runs entirely client-side on your device. Your original source images are loaded into a browser canvas, scaled, and compiled into a binary ICO container without ever contacting our servers.
What output files does this Favicon Generator provide?
You can download the compiled multi-resolution "favicon.ico" directly. You can also download a ZIP archive containing the favicon.ico plus all the individual transparent PNG squares (16px to 256px), which are perfect for modern HTML headers and PWA web app manifests.
