Overview
Use this tool to prepare a favicon set from a single source image without installing design software. It runs in your browser, so the image is processed on your device while you create the icon files you need for tabs, bookmarks, and app installs. It is especially useful when you already have a logo and need practical favicon outputs in multiple sizes. You can start from a square mark, a full logo, or another image and get files that are ready to place into a website asset folder or app build.
Use cases
- New site launchCreate the favicon files needed before publishing a new website so the browser tab and bookmark icon match the brand.
- Logo to icon setConvert a brand logo into a compact favicon set for use in headers, browser tabs, and installable web apps.
- PWA asset prepPrepare the icon sizes often required for an installable web app, using one source image instead of rebuilding each file manually.
- Rebrand rolloutReplace an old site icon with a new branded set and download the updated files in one pass.

Examples
Square logo to favicon set
Input: Input: 1024×1024 PNG logo with a simple white symbol on a dark background.
Output: Output: a favicon set in the usual browser and app sizes, ready to download.
A clean square source gives the most consistent results across small icon sizes.
Product mark from a transparent PNG
Input: Input: transparent 512×512 PNG with a single red wordmark.
Output: Output: crisp icon files that keep the transparent background where supported.
Works well when you want the mark to sit on different site themes.
Artwork used as a site icon
Input: Input: 1200×800 JPG illustration from a campaign landing page.
Output: Output: cropped or adapted favicon sizes suitable for browser use.
Useful when the original image is not a logo but still needs to become a site icon.
FAQ
What happens if my image is not square?
The generator can still create favicon files, but the result may need cropping or may lose detail at very small sizes. A square source image usually produces the cleanest icon.
Can I use SVG, PNG, or JPG files?
Yes, as long as the image format is supported by your browser and by the tool’s import flow. A solid, high-contrast image works best for tiny icon sizes.
Why do small favicon sizes sometimes look simpler than the original image?
A favicon has very little space, so thin lines, small text, and complex gradients can disappear. If the result looks too busy, simplify the source before generating again.
Does the tool create every icon format for every platform?
It creates the common favicon and site-icon sizes, but platform-specific bundles may still need extra files depending on your stack. Check your target platform’s required icon list.
Why does my logo look blurry in one size but not another?
Very small outputs are more sensitive to source detail. If a size looks soft, start with a larger, sharper source image or reduce fine detail in the design.
