Find the image you want to open on your hard drive, then choose to open it. Go to the File menu and select the Open button to complete this. Step 1: To begin adjusting the proportions of an image using Illustrator, we must first open the image. You can now follow these instructions after installing the software on your desktop. If you download the tool from Adobe's main website, you may rest assured that it is virus-free. Illustrator is desktop software, so you'll need to install it on your computer to resize the image. Use 72 as the scale factor of your desired image size in pixels. If the size of your artboard is the same in Pixels as your desired image size, using 72 ppi in the export dialog will produce the same number of pixels. Similarly, if there is a smaller artwork (3" x 2", a Price tag or something) and you want to create a JPEG preview you can achieve an adequate size by setting the ppi to 300. Rather use File > Export > Export As and use a smaller ppi (e.g 12, 15). If you have a large artwork, say 40" 60" and you want to creat a preview image, don't try to use save for web or your computer will try to calculate your artwork in pixels and apply the default export algorithm and would take forever to respond because it makes the process very heavy to compute. One purpose of Export to JPEG dialog (File > Export > Export As) is to create a preview before sending artwork to print (Where exact number of pixels is not important). Metric or imprerial system units depends on ppi factor before converting to pixel units. Why use File > Export > Export As (set ppi) If you are working for a print medium (Printed Ad, Catalog etc), use metric or imperial system units (inch, centimeter, millimeter etc) and always send artwork in vector format.

You can change your units from Document Setup OR Artboard Settings. So even if you want a different size (in percent or pixels) you can do it easily. Always use pixels as document units and use Export for Web Dialog box. If you are producing an artwork for digital medium (Web, App etc), you are not dependant on ppi settings.
