Favicon Generator — Live Tab Preview & Multi-size ICO
Generate favicons from text initials or an uploaded image. Furthermore, a live browser tab preview mockup shows exactly how the favicon looks beside a page title in a browser tab — a unique feature not available in any other free favicon generator. Download multi-size ICO files with 16×16, 32×32, 48×48 and 64×64 pixel variants embedded in a single file.
How to use the Favicon Generator
Choose text initials or upload an image
Select the Text initials tab to create a favicon from letters. Furthermore, enter 1–2 characters and choose a background colour, text colour and shape. Furthermore, select the Upload image tab to use any image. A favicon — the image is cropped to a square and resized to each favicon dimension automatically.
Preview the favicon in the browser tab mockup
The browser tab preview appears instantly showing the favicon at 16×16 pixels beside a page title — exactly. It appears in a real browser tab. Furthermore, the four size previews show the favicon at 16, 32, 48. 64 pixels to confirm legibility at every size. Adjust the initials, colours or shape and the preview updates live.
Download and install
Download the PNG at 64×64 for high-DPI displays, PNG at 32×32 for standard displays. ICO at 16×16 for legacy browser compatibility. Furthermore, the green panel shows the HTML link tags for your page head.
Favicon size guide for all contexts
Modern web applications require multiple favicon sizes. Furthermore, different systems use different sizes. Providing all four ensures sharp display everywhere.
| Size | Used by | Priority |
|---|---|---|
| 16×16 px | Browser tabs (standard), bookmarks | Required — must be present |
| 32×32 px | Browser tabs (high-DPI), taskbar icons | Important for Retina displays |
| 48×48 px | Windows site icons, shortcuts | Recommended for Windows |
| 64×64 px | macOS dock, iOS bookmarks, PWA | Required for Progressive Web Apps |
| 180×180 px | iOS home screen (Apple Touch Icon) | Required for iOS bookmark icons |
How text-to-favicon rendering works
Text favicons render using the Canvas 2D API. Furthermore, the background shape draws first, then the text centres over it using font metrics calculations.

Font size ratio: 52% of canvas size produces legible text at all four sizes
Worked example: creating a brand favicon for a web app
A startup launches a SaaS product called "LazyTools" and needs a favicon. Using text initials mode:
| Setting | Value |
|---|---|
| Initials | LT |
| Background | #1D9E75 (brand green) |
| Text colour | White (#ffffff) |
| Shape | Rounded |
What is a favicon?
A favicon (short for "favourite icon") is a small icon displayed in the browser tab, bookmarks bar and browser history. Furthermore, Progressive Web Apps use the favicon on the device home screen. Browsers request the favicon from the site root — typically /favicon.ico — on every page load. Moreover, a well-designed favicon reinforces brand recognition. Consistent brand colours in the favicon make a site instantly identifiable among many open tabs.
ICO format is the traditional favicon format — it embeds multiple sizes in a single file. Furthermore, modern browsers also accept PNG favicons specified with HTML link tags. Providing both ICO and PNG covers all browser contexts: ICO for legacy browsers, PNG for crisp Retina display. Moreover, Progressive Web Apps require a 192×192 or 512×512 PNG for home screen installation — standard favicons are too small for this context.
Why the 16×16 size is the critical test
A favicon displays at 16×16 pixels in most browser tab contexts. Furthermore, this is smaller than most icons — 16 pixels wide leaves only 2–3 pixel-wide strokes for letter forms. Logos with complex details, thin lines or multiple colours lose legibility at this size. Moreover, designing for the 16×16 constraint first produces favicons that look good at all sizes, while designing for 64×64 and scaling down often produces blurred or unreadable 16-pixel versions.
Why a live tab preview matters
The tab preview shows the favicon at the exact 16-pixel size in its real context — beside a simulated page title in a browser tab shape. Furthermore, the gap between "looks good at 64px" and "legible at 16px" matters greatly for detailed designs. Adjusting contrast and character choice while seeing the 16-pixel result is better than designing large and hoping the small version reads. Moreover, the tab preview catches usability issues before any code is deployed — saving the install-reload-check cycle that most designers repeat multiple times when creating favicons.
