What favicon sizes do I need?
Most sites should include 16x16 and 32x32 PNG icons for browser tabs, a favicon.ico file for legacy support, a 180x180 Apple touch icon, and 192x192 plus 512x512 icons for Android and installable web apps. This generator includes those common outputs in the package.
Should I use PNG or ICO?
Use PNG icons for modern browsers and devices because they keep sharp edges and transparency. Keep favicon.ico as a fallback because some older browsers, crawlers, and bookmark systems still look for it in the site root.
Why does the source image need to be square?
Favicons are rendered inside square slots. A square logo or artwork prevents awkward cropping and keeps the mark centered at small sizes. If your image is rectangular, the generator crops from the center so the result still fits favicon dimensions.
How do I install the downloaded favicon package?
Upload the generated files to your website root or public assets folder, then paste the provided HTML link tags into the page head. After deployment, clear browser cache or test in a private window if the old favicon still appears.
Can I make a favicon from text?
Yes. The text mode is useful for initials, short brand abbreviations, and quick project placeholders. Keep the text to one to three characters, choose a bold font weight, and use strong color contrast so it remains readable at 16x16 pixels.
Why is my favicon not updating after I replace the files?
Browsers cache favicons aggressively. Make sure the files were uploaded to the correct location, reload with cache disabled, test in a private window, or temporarily change the icon file URL if your deployment pipeline keeps serving the old asset.
