What is a Favicon Generator?
A favicon generator creates all the standard-sized icon files needed for your website from a single source image. Modern websites need multiple favicon sizes for different devices and platforms — browser tabs, bookmarks, mobile home screens, and more.
This tool generates sizes: 16×16, 32×32, 48×48, 64×64, 96×96, 128×128, 144×144, 180×180, 192×192, 256×256, and 512×512 pixels. It also produces the HTML snippet you need to include in your website's <head>.
How to Use This Favicon Generator
- Upload an image — Drag and drop an image (PNG with transparency recommended) onto the drop zone.
- Adjust settings — Choose output format, quality, padding, and background color if needed.
- Generate — Click Generate Favicons to create all standard sizes at once.
- Download — Download individual sizes or all as a ZIP archive.
- Copy HTML — Copy the ready-to-use HTML snippet to paste into your website.
Frequently Asked Questions
What favicon sizes are generated?
We generate 11 standard sizes: 16×16, 32×32, 48×48, 64×64, 96×96, 128×128, 144×144, 180×180, 192×192, 256×256, and 512×512 pixels. This covers all modern browser and device requirements.
What image format should I upload?
PNG with a transparent background is recommended for best results. Square images work best since favicons are displayed as squares. JPEG images work too, but the background color option helps fill transparent areas.
How do I use the generated favicons?
Place the generated files in your website's root directory or an assets folder. Then copy the HTML snippet from this tool into your site's <head> section. The snippet includes all the necessary <link> tags for different devices and browsers.
Is this tool safe?
Yes. All processing happens entirely in your browser using the HTML5 Canvas API. Your image is never uploaded to any server, stored, or logged.
