To achieve the best results when converting PNG to ICO, consider these professional tips:
Our PNG to ICO converter is perfect for numerous applications:
An ICO file is an image file format used for icons in Microsoft Windows. ICO files can contain one or multiple images at different sizes and color depths, making them ideal for scalable icons that need to look good at various display sizes. They're commonly used for favicons, application icons, and desktop shortcuts.
Converting PNG to ICO is essential for several reasons: ICO format is required for Windows application icons and favicons, it supports multiple resolutions in a single file for different display contexts, it's widely compatible with browsers and operating systems, and it's the standard format for website favicons that appear in browser tabs and bookmarks.
Absolutely! Your data is completely safe. All conversions happen entirely in your web browser using JavaScript. Your PNG files never leave your device or get uploaded to any server. This ensures maximum privacy and security for your images. Once you close or refresh the page, all data is cleared from memory.
Our converter supports all standard icon sizes: 16×16, 32×32, 48×48, 64×64, 128×128, 256×256, and 512×512 pixels. You can also choose "Auto" to maintain your original image dimensions. Simply click on the size buttons to select or deselect multiple sizes at once. The tool will generate ICO files for each selected size with the size included in the filename.
Yes! Our tool supports batch conversion of up to 10 PNG files simultaneously. Simply drag and drop multiple files or select them all when browsing. Each file will be converted individually, and you can download them one by one or all together in a ZIP archive for convenience.
Each PNG file can be up to 5MB in size. This limit ensures fast processing while supporting most icon creation needs. If you have larger files, consider optimizing them first using image compression tools, as most icons don't require files larger than 1-2MB for excellent quality.

Yes, transparency from your PNG images is fully preserved when converting to ICO format. Our converter maintains alpha channel information, ensuring your icons look perfect with transparent backgrounds. This is especially important for favicons and overlay icons.
Yes, you can use the converted ICO files for any purpose, including commercial projects. Our tool simply converts the format of your images—you retain all rights to your original content. However, ensure you have the rights to use the source PNG images in your projects.
If your favicon isn't displaying, try these solutions: Clear your browser cache and hard refresh the page (Ctrl+F5), ensure the ICO file is properly linked in your HTML head section, verify the file path is correct, check that the ICO file isn't corrupted by testing it locally, and wait a few minutes as browsers sometimes cache favicons aggressively.
