Files can be regarded as documents that may use immediately or save on computer, desktop, mobile devices for later use. Files that lose quality are basically files that tend to look blurred or lose sharpness when zoomed or edited. You can notice the dip in quality by taking a closer look at how the graphic is formatted. The types of file that do not lose quality when enlarged are vector files. Vector files are made up of paths (lines or shapes) and are saved with the extension .ai, .eps, .svg, and .drw
The meaning of the extensions is:
ai = Adobe Illustrator. An ai. file will sow the document in a printable format.
eps = Encapsulated Postscript Vector. An .eps file may be in either text, graphic, or both format.
svg = Scalable Vector Graphic. The size of the graphic can be adjusted.
drw = Database Result Wizard
A vector file can be easily extracted unlike a bitmap file where you can only sketch and edit the file using an image-editing app.
Anytime I am working on a photography file i.e. Raster files especially files that are photoshop and have the extension .jpg, .png, or .gif. so much important details are lost, and the content will look blurry to the user or reader with little quality and sharpness, this is noticeable when zooming the content in the file. The higher the magnification, the blurrier the image/content.
As a graphic designer or writer, you can easily change a raster file to a vector file by modifying and saving the file as either an .ai, .eps, .svg, .drw file. I love working with raw formatted files because they are original but when the content or image I needed can only be gotten online, I just have to use raster files.
