About PDF files

PDF stands for Portable Document Format, a file type Adobe introduced in 1993.

A PDF stores each page as a fixed drawing with exact positions for every letter, line and picture.

That is why a PDF looks the same on a phone, a laptop and a printer, and why it is the standard for invoices, tickets, forms and contracts.

Text PDFs and scanned PDFs

A PDF made by Word or a website contains real text you can search and copy. A scanned PDF only holds photos of paper, so there are no letters to select.

The viewer spots scanned pages and points you to Image to Text, which reads the words from the page images.
