Common questions
What is a favicon?
A favicon is a small icon that appears in browser tabs, bookmarks, and search results. It helps users visually identify your website.
What size should a favicon be?
The most common favicon size is 32x32 pixels for browser tabs. However, modern websites often include additional sizes like 16x16, 180x180 (iOS), and 192x192 or 512x512 for Android and PWA support.
Can I use a PNG as a favicon?
Yes. Modern browsers fully support PNG favicons. You can reference them using the <link rel='icon'> tag in your HTML.
What is the difference between a favicon and an icon?
A favicon is a small icon that appears in browser tabs, bookmarks, and search results. It helps users visually identify your website.
Why do I need multiple sizes?
Different devices and contexts require specific sizes. For example, browser tabs use small 16x16 or 32x32 icons, while iPhone home screens look for high-res 180x180 icons.
Do I still need a .ico file?
Most modern browsers support PNG favicons, but some legacy browsers may still use .ico files. Including both formats ensures maximum compatibility.
Do you support .ico files?
Currently we generate standard PNGs, which are supported by all modern browsers. You can use a `link rel='icon'` tag with these PNGs directly.
Does it work with non-square images?
Yes, but we will center and crop/contain it to a square aspect ratio. For best results, crop your image to a square before uploading.
Can I generate a manifest.json?
This tool focuses on the image assets. You can link these generated icons inside your existing manifest.json file for PWA support.
Is the quality preserved?
Yes. We use a high-quality browser-side canvas resizing algorithm to ensure your icons remain sharp even when downscaled.
