Favicon Generator Guide
Reference for preparing small favicon assets from a source image, including sizes, transparency, ICO use, and browser-side image handling.
Quick answer
Use Favicon Generator to turn a simple square source image into small icon assets for a website. Start with a clean logo or mark, review the tiny sizes, and test it against light and dark browser UI.
What this tool does
The tool prepares favicon-oriented outputs from a local image. It is most useful for quick website publishing, prototype pages, personal tools, and documentation sites where a missing icon makes the site feel unfinished.
Step-by-step use
- Start with a square source image, preferably 512 x 512 or larger.
- Keep the design simple; tiny icons cannot hold much detail.
- Generate favicon outputs.
- Review the smallest size, not just the large preview.
- Add the generated assets to your site and test them in a browser tab.
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation. Avoid entering sensitive brand assets unless you have reviewed the implementation and your own data handling requirements.
Examples
Tool landing page: Create a favicon from a one-letter mark before publishing a small utility page.
Docs site: Prepare a simple favicon so tabs and bookmarks are recognizable during internal review.
Assumptions and limits
Fine text, gradients, and thin strokes may disappear at favicon sizes. Transparency can help on browser chrome, but it should be tested on both light and dark backgrounds.
Common mistakes
Using a detailed logo. Favicons need strong silhouettes.
Only checking the large preview. The 16 px or 32 px result matters most.
