Popular Tools: ICO to JPG JPG to Favicon TIFF to ICO SVG to ICO Compress JPG Favicon Generator
ConvertICO specializes in professional icon conversion with a complete suite of image tools. This JPG to ICO converter creates multi-layer ICO files containing all selected sizes in a single file - the standard format for website favicons, Windows desktop icons, and application shortcuts.
Beyond JPG conversion, our platform offers a full icon ecosystem: use the PNG to ICO converter for images with transparency, the SVG to ICO tool for sharp vector-based icons, or the WEBP to ICO converter for modern image formats. Already have an ICO file? Our Icon Analyzer verifies that it meets all platform requirements.
Website favicons - Convert your logo or brand image from JPG to ICO for browser tab icons. For a complete favicon package with all required sizes, use our JPG to Favicon generator which creates Apple Touch icons, Android icons, and more.
Desktop and folder icons - Windows uses ICO format for desktop shortcuts, folder icons, and application icons. Upload any JPG photo and create a custom ICO with sizes up to 256x256 for crisp display on high-DPI screens.
Application development - Developers building Windows applications need ICO files for executables and installers. Our converter produces standard multi-layer ICO files compatible with Visual Studio, Electron, and other development frameworks.
Need to go the other way? Use our ICO to JPG converter to extract images from existing icon files, or the ICO to PNG converter to get transparent PNG layers.
JPG images are great for photos and complex images, but they don't support transparency. If your icon needs a transparent background (like most logos), consider using our PNG to ICO converter instead, since PNG files preserve alpha transparency in the resulting ICO file.
However, JPG works well for photo-based icons - such as profile pictures, landscape thumbnails, or any icon where a solid background is acceptable. If you need to convert your JPG to PNG first (to add transparency), our JPG to PNG converter can help, and you can even remove the background before converting to ICO.
For the sharpest possible icons from vector graphics, SVG to ICO conversion produces the cleanest results at every size since SVG scales without quality loss.

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.
Absolutely - ICO files created with our converter are fully compatible with all major browsers including Chrome, Firefox, Safari, and Edge. Save as "favicon.ico" and upload to your website's root directory. For a complete multi-platform favicon package, try our Favicon Generator.
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.
After converting your icons, make sure they meet all platform requirements. Use our Icon Analyzer to check ICO sizes, transparency, and browser compatibility. It identifies missing sizes and suggests improvements.
