Description and characteristics

Raster images are made up from a bunch of pixels, tiny squares that have a unique color and tone to make up the image. The higher the resolution, the higher the pixel count, which means that the image will have a higher quality.

Description and Characteristics

A vector image is a type of artwork made up of points, lines, and curves that are defined by mathematical equations rather than solid-colored square pixels. This means that vector graphics can be scaled to any size without losing quality, ensuring that lines and curves remain smooth. Colors in vector graphics are separated into their own shapes, making it easy to change colors.

Raster / Vector

As you can see in this image, the differences between a raster and a vector image rely on its composition. While a raster is made out of multiple squared bits, a vector is made out of lines, curves, polygons and unions in a cartesian board. This makes a vector image have a better quality when zoomed, because its composition is exact. Both of them can be used in different situations depending on the task.

JPEG/JPG (1992): It stands for "Joint Photographic Experts Group", and it is the most used Raster image format in the web because it has a reduced image data compared to other formats. It can't regain quality if it is edited or compressed several times.

PNG (1996): It is a Raster image format that stands for "Portable Network Graphics". It support lossless data compression, as well as transparency. It's the best format for professionals who use the web often.

GIF (1987): It stands for "Graphics Interchange Format", it is a Raster image format, widely used to store lightweight animations and stickers or emoticons on chat apps. It also features lossless data compression.

BMP (Bitmap, 1986): It can handle multiple color depths, profiles, and alpha channels. It can also support data compression.

WebP (2010): It means "Web Picture Format", it is a new, raster image format created by Google. It features even more compressed images from mainly JPEG images, which allows a quick loading of images on web pages.

HEIF / HEIC (2015): It stands for "High Efficiency Image Format", it is a raster image format. It is usually used to store image, although it can also include text, audio, etc.

TIFF (1986): It is an acronym for "Tagged Image File Format", and it is a non-web raster image format widely used by graphic designers and photographers. It allows scanning, word processing, faxing, optical character recognition, desktop publishing, image manipulation, and page-layout applications.

RAW (late 90s-early 00s): It is a raster image format that is not processed nor compressed. It produces the highest amount of quality images. It stands for "Raw Image Format".

PSD (1998): It stands for "Photoshop Document", and it is a non-web raster image format mainly used by the Photoshop program.

What are they useful for?

Vector graphics create smooth, high-quality images that look great at any size. They save time and money for designers and don't lose quality over time. This makes them ideal for logos and other professional branding materials.

EPS: (Encapsulated PostScript, 1987) These files are lossless, meaning that the file stores the information about the graphic in a way that makes it possible to enlarge or reduce the image without losing any quality.

SVG: (Scalable Vector Graphics, 2001) These files have scalability. As the name suggests, one of the main benefits of it, is their ability to be editable.

WMF: (Windows MetaFile, 1988) this file format stores both vector and bitmap information. It was developed as the file format for Microsoft Windows 3.

CDR: (CorelDraw, 1989) These files store vector graphics, text, and other design elements and can also include bitmap images and various effects or filters applied to the design.

PDF: (Portable Document Format, 1993) It displays the exact same content and layout no matter which operating system, device or software application it is viewed on.

AI: (Adobe Illustrator, 1987) Their small file sizes and easy scalability make them a popular choice for many designers and illustrators.
