A favicon generator is a tool that creates the small icons appearing in browser tabs, bookmarks, and address bars. These tiny images (typically 16×16 to 256×256 pixels) represent your website’s brand identity wherever users encounter it online.
Our Favicon Generator goes beyond simple resizing. It lets you customize every aspect – add background colors, borders, padding, and rounded corners – then generates all six standard sizes modern browsers expect, complete with ready-to-use HTML code.
The Problem: Modern websites need multiple favicon sizes. A 16×16 icon looks pixelated when scaled to 256×256 for high-DPI displays. Different browsers and devices request different sizes. Manually creating each size in Photoshop takes forever, and forgetting even one size can cause browser console errors or ugly fallback icons.
The Solution: Our tool generates all required sizes simultaneously from a single source image. You maintain visual consistency across every platform while the tool handles the technical requirements. The generated HTML ensures every browser finds exactly the size it needs.
Click the upload area or drag-and-drop an image. Square images work best, but our scaling options handle rectangles gracefully.
Use the advanced panel to style your favicon:
Background color – Set a solid color behind your image
Border color/width – Add an outline
Border radius – Create rounded or circular icons
Padding – Add space around the image
Scale mode – Choose how the image fits (contain, cover, or stretch)
Watch the live preview grid update instantly. See exactly how your favicon looks at 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels.
The HTML snippet updates automatically. Copy it and paste into your website’s <head> section.

For each target size (16, 32, 48, 64, 128, 256), we create a square canvas of exactly that dimension.
The canvas fills with your selected background color:
We calculate the drawing area after padding:
drawAreaHeight = size - (2 × padding) drawAreaX = padding drawAreaY = padding
Contain Mode (fits entire image):
drawWidth = imageWidth × scale drawHeight = imageHeight × scale
Cover Mode (fills area, may crop):
drawWidth = imageWidth × scale drawHeight = imageHeight × scale
Stretch Mode (exact fit):
drawHeight = drawAreaHeight
The image positions at:
y = drawAreaY + (drawAreaHeight - drawHeight) / 2
If border width > 0, we draw a rounded rectangle outline:
roundRect(borderWidth/2, borderWidth/2, size - borderWidth, size - borderWidth, radius)
The canvas converts to a PNG blob – perfect quality with transparency support.

Rectangular images get letterboxed or cropped. Always start with a square image (or use “Cover” mode intentionally).
The smallest size is crucial – it’s what appears in browser tabs. Check it carefully for readability.
At 16×16, borders thicker than 1px overwhelm the image. Test all sizes in the preview grid.
Modern browsers request specific sizes. Our HTML includes them all – don’t delete any lines.
Detailed photos become unrecognizable at small sizes. Use simple logos or symbols.
If you don’t set a background color, transparent areas become black in some contexts. Always set a background color unless you’re certain.
PNG Only: We generate PNG files (industry standard). ICO format not included – modern browsers prefer PNG anyway.
Square Canvas: All outputs are square; rectangular source images will be fitted into squares.
No Animation: Static favicons only (browser support for animated favicons is limited).
Maximum Radius: 50% creates perfect circles; higher values are capped automatically.
Source Image Quality: Blurry source = blurry favicons. Start with high-resolution images.
Apple Touch Icons: Our HTML focuses on standard favicons; Apple devices may request additional sizes (we include 128×128 and 256×256 which work well).
Modern browsers and devices request favicons at multiple resolutions. The 16×16 size appears in browser tabs and address bars. 32×32 is used for taskbar shortcuts and Windows desktop icons. 48×48 appears in some browser extensions and folder views. 64×64 and 128×128 serve high-DPI displays (Retina screens, 4K monitors). 256×256 future-proofs your site for upcoming devices. Providing all six sizes ensures your favicon looks sharp everywhere, while missing sizes force browsers to upscale – resulting in pixelated, unprofessional appearance. Our tool generates all sizes simultaneously, maintaining visual consistency across every platform.
Search engines don’t directly rank favicons, but they impact user experience signals. A missing favicon creates console errors that can affect crawl efficiency. In search results, favicons appear next to mobile search listings and in browser history – reinforcing brand recognition. Google’s search results increasingly display site icons, making favicons part of your search presence. Additionally, users trust sites with proper favicons; they signal professionalism and attention to detail. Always include favicons in your brand guidelines and treat them as essential website assets, not afterthoughts.
The <link rel="icon"> tag tells browsers where to find your favicon. Adding the sizes attribute lets browsers choose the optimal size for each context. The type="image/png" attribute specifies the format. Modern best practice includes multiple tags pointing to different sizes, allowing the browser to select the most appropriate one. Some developers also include rel="apple-touch-icon" for iOS devices, though modern iOS versions respect standard favicon tags. Our generated HTML follows current W3C specifications and works across all major browsers – Chrome, Firefox, Safari, and Edge.
Favicons are always displayed in square containers. Using a rectangular source image forces decisions about how to fit within the square. “Contain” scaling adds letterboxing (empty space) on the sides. “Cover” scaling crops the image to fill the square. “Stretch” distorts the image to fit exactly. For best results, start with a square source image – your logo on a transparent background works perfectly. If you must use a rectangle, choose “Contain” and add a background color that matches your brand, creating intentional letterboxing that looks designed rather than accidental.
When you update your favicon, browsers may continue showing the old version due to aggressive caching. The favicon is one of the most aggressively cached website assets because it appears on every page. To force updates, add a version parameter to your favicon links: <link rel="icon" href="/favicon-32.png?v=2">. Some developers also use cache-busting techniques or rename files entirely. After uploading new favicons, test in incognito mode and clear your browser cache. Our ZIP download includes the HTML with standard filenames – you can add version parameters manually if needed.
Modern browsers typically request 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256. Our tool generates all six automatically. The browser selects the best size for each device and context.
Upload your image, customize it, then copy the HTML code from the result section. Paste these <link> tags inside your website’s <head> section, upload the PNG files to your server, and you’re done.
Use a simple, high-contrast logo or symbol. Complex photos become unrecognizable at small sizes. Square images work best, and solid colors with clear shapes scale down perfectly.
Yes – our tool preserves transparency. However, some browsers display transparent favicons with a white background by default. Consider adding a background color for consistent appearance across all platforms.
Different devices request different favicon sizes. Desktop browsers typically use 16×16 or 32×32. High-DPI displays (Retina screens) need 64×64 or larger. Mobile devices and taskbars may request various sizes. Providing multiple sizes ensures crisp display everywhere.
Set “Border radius” to 50% and ensure your image has enough padding. This creates a perfect circle. For best results, use “Contain” scaling mode so your image stays centered within the circle.
Yes. While Apple has specific “apple-touch-icon” requirements, our 128×128 and 256×256 PNGs work well when referenced with standard favicon tags. Most modern iOS versions support standard favicon formats.
