Every website needs a favicon, and you do not always start with the ideal source format. Whether your logo is a PNG, JPG, WebP, AVIF, or even a GIF, you can convert it to ICO for use as a standard favicon.
Start with the most common path: PNG to ICO.
Preparing your source image
Before converting, a little preparation goes a long way:
- Make it square. Favicons are displayed as squares. If your image is not square, crop it first or it will be stretched.
- Start at 256x256 or larger. The ICO format can embed multiple sizes, but starting from at least 256x256 ensures you have enough detail.
- Simplify the design. Your favicon will be displayed as small as 16x16 pixels. Fine text, thin lines, and subtle gradients will disappear at that size. Bold shapes and high contrast work best.
Converting from different source formats
QuickImager supports creating ICO files from several input formats:
- PNG: The most common starting point. Handles transparency well. PNG to ICO
- JPG: Works fine for photos or simple logos without transparency. JPG to ICO
- WebP: If your logo is already in WebP format. WebP to ICO
- AVIF: For newer image assets stored in AVIF. AVIF to ICO
- GIF: If you have a simple animated or static GIF logo. GIF to ICO
If your source has transparency and you want to preserve it, start from PNG, WebP, or AVIF. JPG does not support transparency.

QuickImager processes everything locally in your browser. Your images are never uploaded.
Where to place your favicon
The standard approach:
- Name the file
favicon.icoand place it at the root of your site. - Most browsers will find it automatically at
/favicon.ico. - You can also reference it explicitly in your HTML
<head>with a<link rel="icon">tag.
Modern setups often include multiple icon sizes (for Apple touch icons, Android shortcuts, etc.), but favicon.ico remains the universal fallback.
Testing your favicon
After adding the file to your site:
- Check it in at least two browsers (Chrome and Firefox cover most cases)
- Look at the tab icon at actual size, not zoomed in
- Test in a private/incognito window to bypass cached icons
If the icon looks muddy, the source image is probably too detailed for the size. Simplify and increase contrast.

FAQ
- What size should my source image be? At least 256x256 pixels, and it must be square. Larger is fine; the converter will handle sizing. The key is that the design reads clearly when shrunk to 16x16.
- Can I make a favicon from a JPG? Yes. JPG to ICO works well. Just note that JPG does not support transparency, so the background will be solid.
- Is this conversion private? Yes. QuickImager converts locally in your browser with no uploads.
