Frequently Asked Questions

What sizes of favicons do I need?
Most websites need favicons in multiple sizes. The essential ones are 16x16 and 32x32 for browser tabs, 48x48 for Windows taskbar, 192x192 for Android home screen, and 512x512 for Progressive Web Apps.
What image formats work best for favicon generation?
PNG images with a square aspect ratio work best. The tool also accepts JPEG, WebP, and other browser-supported image formats. For best results, start with an image that is at least 512x512 pixels.
How do I add a favicon to my website?
Place the favicon files in your website root directory and add link tags in your HTML head section. For example: link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" for each size.
Is my data safe?
Yes! All processing happens entirely in your browser using the Canvas API. Your images are never uploaded to any server. No data is collected, stored, or transmitted.
Can I generate an ICO file?
This tool generates PNG favicons which are the modern standard supported by all browsers. Most modern browsers prefer PNG favicons over the legacy ICO format.
