RASTER IMAGE FILE FORMATS HOW TO

The JPEG file format is the most common file extension for images. Raster: For when you’re dealing with images that require color blending and continuous tones, such as photographs. Vector: For when you’re designing an illustration with clear contrasts between the elements of the design. So should you go for a vector or a raster program for your file format? That depends on what you’re creating. It means that when you enlarge an image, it won’t affect its quality. Vector images are made-up of points, curves, and lines that are defined by mathematical equations. Raster images are built up in pixels, which means that when you enlarge an image, you stretch the pixels and lower the quality.

Going for vector as opposed to raster depends on whether you want to scale or resize images. In this way, if you want to reduce your file’s size, you can easily revert to its original quality. If you’re not too bothered with saving space, and you want to keep your file’s original quality, go for lossless compression. So when should you use each type of file compression? It depends – do you want to save space at the cost of altering the quality of the file? Then a lossy compression is the way to go. Lossless compression groups all the pixels into the same color category, making indexing easier. Lossless compression is when you want to preserve your image’s quality, while keeping the size of the file small. Lossy compression is when your image’s data has been corrupted, and colors are averaged out through a mathematical formula.

The type of file compression you use depends on whether you want to preserve the original data of a file. Large file size incompatible with web usage.Īre you unfamiliar with terms like lossy and lossless compression or raster and vector? No problem, we’ll be introducing these for you below!
