There are many image formats to choose from and choosing the most appropriate can enhance your brand assets and images. This simple guide offers a detailed breakdown into the world of image formatting. This guide provides insights into the six main types of image formatting which are:

RGB

(Red, Green, Blue) colour mode is for anything that is computer-based design. This includes websites, apps, banner ad and any other design created for electronic use.

The best file formats are: JPEG, PSD, PNG and GIFS.

CMYK

(Cyan, Magenta, Yellow, Black) colour mode is used for print design. This includes logos, business cards, stationary, illustration, packaging and any other designs used for print.

The best file formats are: PDFs, AI and EPS

VECTOR

Vector images are made up of points, lines and curves that can be infinitely scaled without any loss in image quality. 

Vector images are usually used in graphic design, animation, print making, embroidery and sign making

RASTER

Raster images are made up of a set grid of dots called pixels, where each pixel is assigned a colour value. Unlike a vector image, raster images are resolution dependent. When you change the size of a raster image, you shrink or stretch the pixels themselves, which can result in a significant loss of clarity and produce very blurry images.

Different raster algorithms exist such as : Ordered Dithering,

Error Diffusion and Colour and black/white

LOSSLESS

Lossless image formats capture all the data of your original file. Nothing from the original file, photo, or piece of art is lost- hence the term “lossless”. The file may still be compressed, but all lossless formats will be able to reconstruct our image to its original state

LOSSY

Lossy image formats approximate what your original image looks like. For example, a lossy image might reduce the number of colours in your image or analyse the image for any unnecessary data. These clever technical tricks will typically reduce the file size, though they may reduce the quality of your image


LOSSLESS VS LOSSY

Both have different advantages and uses. The use depends on purpose, audience and brand assets along with the skillsets of the person editing and compressing these images
