![]() JPEGīecause JPEGs produce such low file sizes, you can fit more photos on your memory card (so long as you don't plan on any heavy editing afterwards) (Image credit: Future) ![]() Examples of vector file formats are AI, EPS and SVG. As a consequence you will often find these being used for logos, icons and fonts, which are expected to be flexible given any situation. Because their form is defined by a set of mathematical parameters, they can be scaled up and down without any loss of quality. Vector images are mathematical calculations, rendered in the form of geometric paths, created purely on a computer. If you want to learn more about resolution and resizing raster graphics, read our piece on how to resize images in Photoshop. Common raster file formats include JPEG, PSD, PNG and TIFF. Lossy compression removes pixels to produce a close match to the image, while lossless uses exact reproductions of the original image. Raster images can be described as lossy or lossless, terms that refer to the compression they use. The downside is that they are dependent on resolution, suffering from image degradation and loss of detail when scaled up. Raster images are used for complex images that have smooth gradients of colour and undefined edges, such as photographs.
