Design Assets: Which File Type Do I Use?

With the launch of our new Design Assets product category, you’ll likely see some file types (SVG, AI, PNG, JPEG) that you’ve not encountered before in the Igniter library.

Each of these file types have their own specific use cases and strengths, but they all fall into one of two categories: 1) vector graphics - graphics based on math/geometry that are resolution-independent and can be infinitely scaled without losing quality, and 2) raster or bitmap graphics - graphics based on pixels that cannot be scaled without affecting the quality of the image. Below are the 4 most common types you’ll see within Design Assets.

SVG

SVG, or Scalable Vector Graphics, is a  vector image format. Unlike raster images (like JPEG or PNG), SVG files are resolution-independent, meaning they can be scaled to any size without losing quality. These are the most universal, and most simplistic form of vector-based graphics, and can be opened or used in almost any software.

AI

Similar to SVG, an AI file is an Adobe Illustrator Artwork file, primarily used for vector graphics. The main difference is that it may contain data, formatting, or features that are unique to Adobe Illustrator, and therefore it is not as universal. But there are several software titles that will allow you to open Illustrator files, like Inkscape.

PNG

A PNG (Portable Network Graphics) file is a raster image format that supports lossless compression, meaning it retains high quality without losing data. PNG files also support transparency, making them ideal for images that require transparent  backgrounds.

JPG

A JPG (or JPEG) file is a widely used raster image format known for its lossy compression, which significantly reduces file size by discarding some data. This makes it less suitable for images that require high detail but ideal for photographs and other colorful images.

Wrapping up, knowing the ins and outs of each image format—SVG, AI, PNG, and JPG—can really help you make the best choice for your projects. Picking the right format means your visuals will look their best and load smoothly, whether you're designing for a website or creating a print piece. It’s all about matching the format to the job and letting your work look its best!
