ICO Convert is a free online icon maker and favicon generator, with it you can make icons from png or jpg images, just upload a photo of yourself, resize and crop it, convert to a shape you like, add borders and shadows, and save it as a PNG image or Windows icon. Long story short; while experimenting with ideas on Puppeteer for my next talk, I found myself building an open source CLI tool — pwa-asset-generator! It automatically generates splash screen and icon images for your Progressive Web App in order to provide native-like user experiences on multiple platforms.
What are Favicons?
Favicons are small 16x16 icon files that are displayed next to the URL of your site in a browser's address bar. Additionally they're often displayed next to the name of your site in a user's list of open tabs and bookmark listings making it easier for the user to quickly identify amongst other sites.
What are App Icons?
App Icons are the images you press on your smartphone to launch an application. As newer phones are released with higher resolution screens, higher resolution app icons are needed. Developers still want to maintain support for the older phones with lower resoltion so when you create an app icon you need to create several size variations of the same image. This is true for all smartphones like the iPhone and Android, and even tablets like iPad.
What does this tool do?
Although many modern web browsers support favicons saved as GIFs, PNGs or other popular file formats all versions of Internet Explorer still require favicons to be saved as ICO files (a Microsoft icon format). This tool provides an easy way to convert any GIF, PNG or JPEG to ICO which is supported by all modern web browsers. It also enables you to create favicons from scratch via a handy online editor. Additionally the editor lets you manually tweak generated favicons to ensure the best possible result.
