GIF files support transparent backgrounds, unlike JPEGs, but do not support effects (such as gradients or drop shadows). A GIF has a limited color palette of 265 colors, so it is best practice to only use gifs for more simplistic graphics, such as buttons, icons, or text (items that only use a few solid colors). GIF files are another form of web-based graphic. JPEGs are best suited for web-based photographic images GIFs (Graphics Interchange Format) - YourFile.gif Because they are a raster-based file type, they do not resize well. NOTE: You cannot export a JPEG file with a transparent background-It will always have a white background. JPEG files are fine for web stuff, but you should avoid using them in print because they are usually exported at 72 ppi (pixels per inch), while the standard for printing is usually 300 ppi, resulting in your OK-looking image suddenly becoming super tiny on print. Lossy means that the file “loses” data (permanently) when it is compressed, reducing quality (though this is usually not noticeable if done right). That being said, JPEGs are a lossy compression file format (which reduces file size and quality during saving). On the web, you want your images to be as small as possible so that your pages load quickly. jpg), are best suited for web-based photographic images, such as banners or email designs. ![]() JPEGs are the poster child of file extensions, the one everyone has seen. Vector vs Raster - Different Types of Raster-Based Graphics JPEGs (Joint Photographic Experts Group) - YourFile.jpg Now that you’ve got the basics down, let’s talk more in-depth about some specific file formats. Illustrator and Inkscape are vector-based programs, meaning that any files exported from these programs will be constructed using mathematical equations or geometric shapes. TIP: Illustrator is great for working with vector file types, though Inkscape works too. It’s much easier to make an image smaller than it is to make an image larger. Tip: Always save your original logo file in a relatively large size, like 1000 pixels or more, so you can easily implement it in other promotional materials down the road. ![]() They also work well for graphics that need frequent resizing, like your logo, which you might place on everything from your business card or letterhead to the tailgates on every truck in your fleet or a billboard on I-35.Ĭommon vector based files are EPS and AI files. Vector-based files are best for anything you’re going to send to the print shop. In contrast, vector-based images use mathematical equations or geometric shapes, such as points, lines, or curves, to form an image.Īs a result, vector-based images can be infinitely scaled without loss of quality, which is why, in the above image on the left, despite the zoomed view, there is no reduction in quality. Photoshop and these other programs are raster-based programs, meaning that any files exported from photoshop will be made up of pixels. TIP: Photoshop is great for working with raster file types, though GIMP and aren’t bad either. JPEGs, GIFs, PNGs, and TIFFs are raster-based file types. Basically, you’re forcing your computer to magically generate pixels that do not exist, creating that grainy appearance.
