There are a few things you need to know before starting vectoring an image in Illustrator. First, the file size of an Illustrator vector file is usually much smaller than a PNG or JPEG. This is because Illustrator vectors are made up of lines and shapes, which are much easier to create and manage than images that are filled with color and text. Second, you should always use the default font family for your vector file. This will ensure that all the text and icons in your image look consistent and professional. Third, make sure that all your layers are set to “Layers” mode. This will help keep everything organized and easy to work with while you’re vectoring. Finally, be sure to save your vector files as *.ai or *.eps files so that they can be used in any software that supports AI files (such as Adobe Photoshop).
