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 on your device. Your original source images are 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.
