How to convert PNG to FAVICON
A favicon is the small icon displayed in browser tabs, bookmarks, and address bars. The traditional format is ICO (which can contain multiple sizes: 16x16, 32x32, 48x48), but modern browsers also accept PNG and SVG favicons. Converting a PNG logo or icon to a favicon-ready format means resizing it to the standard dimensions and packaging it correctly so browsers pick it up automatically.
The conversion runs in your browser via WebAssembly. Your logo never leaves your device. The output is a downloadable .ico or .png file at the correct dimensions, ready to reference in your HTML head tag.
Upload your PNG
Drop your logo or icon as a PNG. Square images produce the best results; rectangular images will be cropped or padded. Transparent backgrounds are preserved.
Choose output sizes
Select which sizes to include: 16x16 (browser tab), 32x32 (taskbar), 48x48 (desktop shortcut), 192x192 (Android home screen). A multi-size ICO is the most compatible choice.
Convert
The WebAssembly engine resizes the PNG to each selected dimension and packages the sizes into a single ICO file.
Download and deploy
Download the favicon.ico file, place it in your website's root directory, and add the correct link tag to your HTML head.
Frequently asked questions
What HTML tag do I need to reference the favicon?
<link rel='icon' type='image/x-icon' href='/favicon.ico'> in your HTML head. For PNG: <link rel='icon' type='image/png' href='/favicon.png'>.
What size should my favicon be?
A multi-size ICO containing 16x16, 32x32, and 48x48 covers all browsers. Add 192x192 and 512x512 PNG variants for Android and Apple touch icons.
Should I use ICO or PNG for favicons?
ICO is more broadly supported, especially in older browsers and bookmark managers. PNG is cleaner and simpler. Using both (ICO for browsers that need it, PNG for modern ones) is the safest approach.
Is my logo uploaded to a server?
No. Processing is local in your browser via WebAssembly.
What if my logo is not square?
Most favicon formats require square images. The converter will either crop to a square or add padding. Adjust your source image to a square aspect ratio before converting for best results.
