We have previously mentioned a number of websites to download free icons. These resources include tons of high-quality free icons, but sometimes what you want is not readily available. If that is the case and you want to create your own icon, there is a web app that will come in very handy.
iConvert is an application that converts regular images into icon files, free of cost. Simply upload any image file with a PNG, JPG, TIF, BMP or any other commonly used image format, and iConvert will convert that into an icon file for you.
Once converted, you can download your icon as a .ico file which is a windows native icon file, .hqx or .icns files which are icon files for MAC OS or download them as simple .png to use with Linux. The converted .png file is available for download in a number of different sizes.
