Difference between raster and vector files

Raster image

A raster image is based on a dot-matrix or pixel grid and requires a high resolution in order to be printed or adapted to multiple display formats.

It is not scalable; if you increase the size of a raster image, this image will look blurry. To prevent this, all you can do is leave the image in its original size or make it smaller.

Formats: PSD, JPEG, TIFF, GIF, PNG, RAW

Vector image

A vector image allows us to maintain the quality of the design across multiple formats and resolutions. In a vector file, each point, line, and shape created is fully scalable.

Formats: EPS, AI, SVG, DXF
