Frequently Asked Questions
What is an ICO file?
An ICO file is a container format that can hold multiple images at different sizes. It's commonly used for website favicons and Windows application icons.
Why do I need multiple icon sizes?
Different platforms and devices require different icon sizes. Browsers use 16x16 and 32x32 for tabs, while mobile devices may use 180x180 or larger. Including multiple sizes ensures your icon looks sharp everywhere.
Is my image uploaded to a server?
No. All image processing happens entirely in your browser. Your images never leave your device, ensuring complete privacy.
What's the difference between ICO and PNG?
ICO can contain multiple images at different sizes in one file, while PNG is a single image. ICO is specifically designed for favicons and application icons.
Can I use SVG files?
Yes, SVG files are supported. However, animated SVGs will only use the first frame. The SVG will be converted to a static PNG image within the ICO file.
What is an ICO file?
An ICO file is a Microsoft icon format that can contain multiple images at different resolutions. This allows the operating system or browser to choose the most appropriate size for the display context. ICO files are commonly used for website favicons, application icons, and folder icons.
What is a Favicon?
A favicon (short for 'favorite icon') is a small image that represents your website. It appears in browser tabs, bookmarks, history, and search results. A well-designed favicon helps users quickly identify your site and adds professionalism to your brand.
ICO vs PNG
While PNG is a single-image format, ICO can contain multiple images at different sizes (16x16, 32x32, 48x48, etc.) in one file. This makes ICO ideal for favicons, as browsers can choose the best size for different contexts. PNG favicons work in modern browsers, but ICO provides better compatibility.
Required Favicon Sizes
For complete favicon coverage, you should provide: 16x16 (browser tabs), 32x32 (taskbar), 48x48 (Windows desktop), 180x180 (Apple touch icon), 192x192 (Android Chrome), and 512x512 (PWA). Our tool generates all these sizes automatically.
How to Add Favicon to Your Website
Add the generated HTML code to your website's <head> section. Upload the favicon files to your website's root directory. The code includes links for standard favicons, Apple touch icons, Android Chrome icons, and the web manifest for progressive web apps.
Why Do Small Icons Look Blurry?
At very small sizes (16x16), fine details become indistinguishable. For best results, use simple, bold designs with high contrast. Avoid thin lines, small text, or complex details. Test your favicon at actual size to ensure it's recognizable.
How to Make Clear Icons
Start with a high-resolution source image (at least 512x512). Use simple shapes and bold colors. Avoid gradients and shadows that don't scale well. Test at multiple sizes to ensure clarity. Our tool automatically optimizes each size for best results.
Transparent Background Support
PNG and WebP images with transparency are fully supported. The alpha channel is preserved in the generated ICO file. For JPG images (which don't support transparency), you can add a solid background color. Transparent icons work best on varied background colors.
Privacy & Security
All image processing happens entirely in your browser. Your images are never uploaded to any server. The generated ICO files and favicon packages are created locally and downloaded directly to your device. We have no access to your images or generated files.
