SVG and PDF explained
SVG is not a picture of an image — it is XML describing shapes, paths and text. Because it stores instructions rather than pixels, it renders perfectly at any size, from a favicon to a billboard.
PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.
- Where SVG files come from
- Design tools like Figma and Illustrator, and icon libraries.
- Where PDF is used
