Quick Answers

Frequently Asked Questions (FAQs)

Find answers about icon sizes, file formats, and the technology behind our generator.

A **favicon** is the small icon displayed in browser tabs, bookmarks, and search results. Browsers and devices use different sizes (e.g., 16x16, 32x32, 48x48) for various contexts. Providing multiple sizes ensures your icon looks crisp everywhere.
We use an iterative downscaling algorithm based on HTML Canvas. Instead of resizing directly from a large image to 16x16, the image is progressively halved (e.g., 256 -> 128 -> 64 -> 32 -> 16), preserving pixel quality and detail at the smallest resolutions.
PNG icons offer better quality and transparency and are used by modern browsers. The **favicon.ico** format is an older, container format still required by some legacy systems and specific browser features. Our package includes both for universal compatibility.
No. This tool is **100% client-side**. Your image remains entirely within your web browser. All resizing, processing, and ZIP file creation happen locally on your device.
A square image of **256x256 pixels** or larger is highly recommended. The better the initial quality and resolution, the better the quality of the final downscaled small icons will be.
