Yes - ConvertICO is completely free with no hidden fees, subscriptions, or watermarks. Convert unlimited JPG files to ICO format without registration.
ICO is the standard image format for website favicons, desktop icons, and Windows application icons. Unlike regular images, ICO files can contain multiple sizes (16x16 to 256x256 pixels) in one file, ensuring your icon displays perfectly across different devices and screen resolutions. Use our Icon Analyzer to verify your ICO files meet all requirements.
You can upload JPG files up to 5MB each, with support for up to 20 files simultaneously. For best results, use high-resolution images (at least 256x256 pixels) to ensure quality across all icon sizes.
Yes - select from multiple icon sizes including 256x256, 128x128, 64x64, 48x48, 32x32, 24x24, 20x20, and 16x16 pixels. You can choose specific sizes or include all sizes for maximum compatibility. Use the "Recommended" preset for the most common sizes.
Yes - batch conversion supports up to 20 JPG images simultaneously. When you convert 5 or more files, a ZIP archive is created automatically for easy download.
No software installation required. ConvertICO works entirely in your web browser on any device - Windows, Mac, Linux, or mobile. Simply upload, convert, and download.
Yes - both .jpg and .jpeg file extensions are fully supported. They are the same format with different extensions, so either will convert to ICO perfectly.

ICO format supports multiple sizes in one file and works with all browsers including older ones. PNG favicons are simpler but only support a single size per file and may not work in older browsers. For maximum compatibility, use ICO. Need to convert between formats? Try our ICO to PNG converter or PNG to ICO converter.
Your privacy is protected. All uploaded files are processed securely on our servers and automatically deleted within 24 hours. We never share or use your files for any other purpose.
Yes - ICO files are the standard format for Windows desktop icons and shortcuts. After conversion, use your ICO file for custom folder icons, application shortcuts, or any Windows icon needs. For resizing existing icons, try our Icon Resizer.
For the sharpest results, start with a high-resolution JPG image (at least 256x256 pixels, ideally 512x512 or larger). Smaller source images will look pixelated when scaled up to larger icon sizes. You can also try our Image Upscaler to enhance low-resolution images before converting.
That's normal - JPG doesn't support transparency, so your icon will have a solid background. Learn why this happens and how to fix it in our guide: Why Your JPG Icon Has a White Background - and How to Fix It.
