GIF and PDF explained
GIF is a 1987 format limited to a 256-colour palette per frame, with support for simple animation and one fully transparent colour. Its longevity is cultural rather than technical — nothing about it is efficient by modern standards.
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 GIF files come from
- Reaction images, simple UI animations, and screen recordings shared in chat.
- Where PDF is used
- Contracts, invoices, reports, forms, academic papers and scanned documents.
