PNG Image Format
PNG Converter
PNG is a common type of image file. The file extension PNG is short for ‘Portable Network Graphic’, and the format was created to offer improvements over the GIF format. Like JPG, PNG is a 2D ‘raster’ image format. However, unlike JPG, PNG files can have transparent or semi-transparent backgrounds around a design. This makes them perfect to use for company or brand logos or graphics that need to be placed in documents or over other images. They are also sometimes used for detailed graphs or diagrams online.
PNGs use lossless compression, which offers high-quality images with more colours. However, this often means PNG files are bigger than some other formats like JPG. The PNG format is open source, and you can open these files using almost all devices, image editors and viewers. Many smartphones now allow you to easily remove backgrounds and create PNGs of individual parts of photos.

ICO Image Format
ICO is the name of the format used for icons on Windows, such as the paintbrush and palette used for MS Paint, the tab file image for folders on File Explorer, or the different-coloured ‘W’, ‘X’, ‘P’, ‘O’ and ‘A’ logo icons used for Microsoft Office apps and files. The ICO format was developed by Microsoft especially for Windows. It’s not possible to associate an image with an app or file on a Windows device without using an ICO image.
ICO files contain one or more 2D ‘raster’ images – usually in different sizes so that they can be scaled appropriately as needed. The images are normally a lot smaller than most standard image files. You can use certain image editors and drawing programs to create ICO files from JPG or PNG files, or you can create the icons from scratch. Microsoft Paint, Adobe Photoshop and Preview for Mac can all be used to create ICO files. You can also use these programs to open and view ICO files.

If you prefer, you can also create ICO files on your device by opening the image using MS Paint, resizing it to 32x32 pixels, and then saving it, changing the end of the file name to .ico from .png. You can follow a similar process with Preview on Mac, or in Photoshop.
