How to Convert JPG to ICO Favicon - Step by Step Guide

Step 1

Upload Your JPG Image

Start by uploading your JPG/JPEG image. For best favicon results, use a square image (256×256px or 512×512px recommended):

•
Click to upload: Click the upload area or "Upload" button to select your JPG file
•
Drag and drop: Drag your JPG logo or photo directly into the upload area
•
Try the sample: Click "Sample" to see demo favicon generation
•
Privacy guaranteed: Processing happens in your browser - files never uploaded

Recommended JPG Sizes for Favicons

For best quality at all sizes, start with:

→
Optimal: 512×512px square JPG image
→
Minimum: 256×256px for all standard favicon sizes
→
Design tip: Keep your design simple - it needs to look good at 16×16px
Step 2

Preview Your Image

Once uploaded, you'll see a preview of your favicon source image. The converter will display:

•
Image preview: Visual preview of your JPG image
•
File information: Original file name and size
•
Image dimensions: Width and height verification
Step 3

Automatic Multi-Size Generation

The conversion happens automatically and instantly after upload! Our custom ICO encoder creates a professional multi-resolution favicon using the HTML5 Canvas API:

•
6 standard sizes: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels
•
High-quality scaling: Uses advanced image smoothing for each size
•
Single file output: All sizes packed into one favicon.ico file
•
Automatic conversion: JPG automatically converted with transparency support

ICO Size Usage Guide

Each size serves a specific purpose as recommended by MDN Web Docs:

16×16: Browser tabs, bookmarks
32×32: Taskbar, address bar
48×48: Desktop shortcuts
64×64: High-DPI displays
128×128: Chrome Web Store
256×256: Retina displays
Step 4

Download & Use Your Favicon

Once conversion is complete (happens automatically!), you have these options:

•
Download as favicon.ico: Click "Download" to save your multi-size favicon
•
Copy to clipboard: Click "Copy" for quick usage
•
Place in root: Upload favicon.ico to your website's root directory
•
Convert more: Use "Clear" to create another favicon

How to Use Your Favicon

Add this to your HTML <head> section per W3C guidelines:

<link rel="icon" type="image/x-icon" href="/favicon.ico">

Frequently Asked Questions

What size should my JPG be for best results?

For optimal quality at all favicon sizes, start with a square JPG at least 256×256 pixels. A 512×512px source provides even better quality. Make sure your design is simple and recognizable when scaled down to 16×16px.

Does JPG to ICO conversion support transparency?

JPG files don't support transparency, but the ICO file will be created with 32-bit RGBA support. If you need a transparent favicon, consider using our PNG to ICO converter instead, as PNG supports transparency.

Why convert JPG to ICO instead of using JPG directly?

According to web standards, ICO files are containers that hold multiple images at different resolutions. This allows browsers to choose the most appropriate size for each context (tabs, bookmarks, shortcuts) without additional requests, providing better performance and compatibility.

Is this favicon generator free?

Yes, absolutely! This JPG to ICO converter is completely free with no watermarks, registration, or file limits. All processing happens in your browser for maximum privacy.

Can I use photos as favicons?

Yes! You can convert any JPG photo to a favicon. However, photos often have too much detail and may not look clear at small sizes (16×16px). For best results, use simple logos, icons, or graphics with clear, bold designs. Check browser support for details.

How do I test my favicon?

Upload favicon.ico to your website's root directory and clear your browser cache. Check browser tabs, bookmarks, and history. You can also use online favicon testers or browser developer tools to verify it loads correctly. If you need to extract your favicon later, use our ICO to JPG converter.
