Picture record types and arrangements are separated into two fundamental various classifications: raster picture documents and vector picture documents. 

How about we investigate every class. 

Raster Image File Formats 

The most widely recognized picture designs for the web (JPEG, GIF, and PNG) are all together under the raster class. 

Raster picture record types show static pictures where each pixel has a characterized shading, position, and extent dependent on their goal (for instance 1280×720). 

Since they're static, you can't productively resize the pictures, the first plan and pixels will essentially get extended to occupy the additional room. This winds up making a foggy, pixelated, or in any case, contorted picture. 

By far most of the photos or pictures you see on the web utilize a raster picture design. Read this article about What is a vector image, why, and how can you use it?

Vector Image File Formats 

SVG, EPS, AI, and PDF are instances of vector picture document types. 

Dissimilar to the static raster picture document designs, where each plan shape and shading is attached to a pixel, these organizations are more adaptable. 

Vector illustrations rather utilize an arrangement of lines and bend on a cartesian plane, scaled in contrast with the absolute zone, no single pixel. 

This implies you can perpetually expand the first picture goal with no misfortune in quality or bending. 

As should be obvious, the distinction between quality when amplified 7x is totally exceptional. 

Since the SVG computes the positions dependent on a level of the absolute region, and not pixels, there's no pixelation by any means. Know more about What is a vector image, why, and how can you use it?
