    Image to ico Easymode

    Image to ico Easymode

    Image to software icon or favicon made simple

    This program makes it simple to get a proper .ico image for your PC software or website favicons. It focuses on what matters and tells you exactly what you need. You feed it an image (png, jpg, gif), it will crop it if its not a square, then it will resize and convert it to the correct format. I have support for these: - Windows PC Exe Programs - 16×16, 32×32, 48×48, 256×256 .ico bundled - Website Favicon - 32x32 .ico - Android Phone Apps - 192x192 .png - Progressive Web Apps (PWA) - 512x512 .png I recommend uploading images atleast 512x512px tall/wide, unless you're doing pixel perfect icons and just want an easier 'convert to .ico format' tool. (Source code is included as it is a standalone offline html file that works in any modern web browser.)
