A favicon is the tiny icon that sits beside your page title in a browser tab. Without one, visitors see a generic globe, and your tab blends into a row of identical tabs. Kwebby's Favicon Generator Tool makes one from a letter or a pair of initials in about a minute.
You pick two colors, choose a square or circle, set a size and download the result. This guide explains how the tool works, which sizes it can export and how to put the icon on your site. The tool is part of Kwebby's Free Image Tools Online.
Key Takeaways
- Kwebby's Favicon Generator Tool makes an icon from one or two letters, with a background color, a text color and a square or circle shape.
- The size slider steps through 16, 32, 48, 64, 96, 128, 180, 192, 256 and 512 pixels, the common favicon and app icon sizes.
- Download PNG saves one PNG at the selected size, such as favicon-180x180.png. Download ICO saves a real favicon.ico that holds 16, 32 and 48 pixel versions.
- Google recommends a square favicon larger than 48 by 48 pixels, with a stable file URL that Googlebot can crawl.
- The tool makes letter icons only and cannot upload a logo. Download the 180, 192 and 512 pixel PNGs for Apple and Android icons.
- Use strong contrast between the letter and the background so the icon stays readable at 16 pixels.
What Is the Kwebby Favicon Generator Tool?
Kwebby's Favicon Generator Tool is a free tool that creates a favicon from one or two letters. You choose the background color, the text color, a square or circle shape and a size from 16 to 512 pixels. A live preview shows the icon before you download it as PNG or ICO. The work happens in your browser.
It suits sites that need a clean, branded letter icon fast, such as a new blog, a landing page or a test project.
Key Features and How It Works
The tool draws on an HTML canvas in your browser, then saves the canvas as an image file.
Text / Initials
Type one or two characters in the Text / Initials box. The field accepts a maximum of two characters, which keeps the letters large enough to read in a tab. The letter is drawn in bold Arial, centered on the icon.
Background and Text Color
Two color pickers set the Background and the Text Color. The starting values are a white letter on orange. You can change both with the color window or paste codes found with the Color Picker.
Shape
Choose square or circle. A square fills the whole canvas. A circle leaves the corners transparent, which suits tabs with light or dark themes.
Size
The Size slider steps through 16, 32, 48, 64, 96, 128, 180, 192, 256 and 512 pixels, with 64 as the default. The preview shows the icon and reads, for example, "Preview (64×64)". Previews above 256 pixels are shown scaled down on screen.
Download PNG and Download ICO
Download PNG saves the icon at the selected size, named after it, such as favicon-32x32.png. Download ICO builds a real multi-size favicon.ico with 16, 32 and 48 pixel images inside, whatever size the slider shows. The ICO stores each size as PNG data, which all current browsers read.
Why Favicons Matter
A favicon helps people find your tab among many, identifies your site in bookmarks and can appear next to your result in Google Search. Google's guidelines ask for a square image of at least 8 by 8 pixels and recommend one larger than 48 by 48 so it looks good on every surface. Google supports ICO, PNG, JPEG and other formats.
Google also requires that Googlebot-Image can crawl the file and that Googlebot can crawl your home page. The favicon URL should stay stable. Crawling can take from several days to several weeks, and a favicon is not guaranteed to appear in results even when every guideline is met.
How to Use the Favicon Generator Tool
- Enter your letters. Type one or two characters in Text / Initials, for example your brand's first letter.
- Set the colors. Choose a Background color and a Text Color. Use the Color Picker if you need exact HEX codes.
- Pick a Shape. Select square or circle.
- Set the Size. Drag the slider. Use 32 for a classic tab icon, 48 or 96 to follow Google's larger size advice, 180 for an Apple touch icon, or 192 and 512 for Android.
- Download the file. Check the preview, then click Download PNG or Download ICO.
- Add it to your site. Upload the file to your site root and add the link tag to your page head. Then use Get Source Code of Webpage to confirm the tag appears on the live page.
Best Practices for Favicons
Small icons fail in predictable ways. These checks avoid most of them.
Choose high contrast
The icon may be shown at 16 pixels, so low contrast turns into a blur. White text on the default orange (#f97316) measures about 2.8:1. Dark gray (#1f2937) on the same orange measures about 5.2:1, which reads better. Common mistake: choosing two colors from the same family.
Keep it to one or two characters
Short text stays legible. A single bold letter is usually clearer than two. Common mistake: typing a whole word and expecting it to fit.
Pick a size above 48 pixels for the source file
Google recommends a favicon larger than 48 by 48 pixels. Browsers shrink large images for tabs, so a 96 or 192 pixel file works at every size. Common mistake: exporting at 16 pixels and finding the edges look rough.
Add the right link tag
For a PNG file, rename it favicon.png or keep its name, and put this in your page head: <link rel="icon" href="/favicon.png" type="image/png">. For the ICO file, use <link rel="icon" href="/favicon.ico" sizes="any">, since it holds several sizes. The Evil Martians favicon guide keeps a 32 by 32 favicon.ico as the fallback for older browsers.
Plan for Apple and Android icons
Current guides list a 180 by 180 Apple touch icon and 192 and 512 pixel icons for a web manifest. Set the slider to each of those sizes and click Download PNG once per size. Apple applies its own rounded corners, so use the square shape for the 180 pixel icon.
Start from a square
If you later swap letters for a logo, crop it to a square with the Image Crop Tool first so it does not stretch.
Common Use Cases
- New websites: give a blog or landing page a branded tab icon before launch.
- Staging and test sites: use a different color so you can tell environments apart in your tabs.
- Web apps and dashboards: make quick placeholder icons for internal tools.
- Personal projects: use your initials for a portfolio or link page.
- Brand color checks: test how a brand color looks at tab size.

Frequently Asked Questions (FAQs)
What is a favicon?
A favicon is the small icon that appears in browser tabs, bookmarks and sometimes search results next to your site name. It identifies your site at a glance. Most favicons are simple shapes, letters or logos on a solid color.
How do I create my own favicon?
Choose a simple design, such as one or two letters on a solid color, and export it as a square image. With Kwebby's Favicon Generator Tool, enter your letters, pick colors and a shape, set a size and click Download PNG or Download ICO.
What size should a favicon be?
Google says a favicon must be square and at least 8 by 8 pixels, and recommends one larger than 48 by 48 pixels. Many guides also list 32 by 32 for favicon.ico, 180 by 180 for Apple devices and 192 and 512 pixels for web apps.
Do I need a favicon.ico file?
Not strictly. Google Search accepts PNG and other formats, and browsers read an icon from a link tag. A 32 by 32 favicon.ico is still the usual fallback for older browsers. Kwebby's Download ICO button saves a favicon.ico with 16, 32 and 48 pixel images inside.
How do I add a favicon to my website?
Upload the file to your site root and add a link tag inside the page head, for example <link rel="icon" href="/favicon.png" type="image/png">. Google needs time to recrawl your home page, which can take days to weeks.
Can I use a logo or image instead of letters?
Not with this tool. It makes icons from one or two characters only. To use a logo, crop it to a square, resize it in an image editor and save it as a PNG.
Final Thoughts
Kwebby's Favicon Generator Tool is the fast route to a clean letter icon. Pick strong colors, keep the text short and export at a size above 48 pixels.
