PDF (Portable Document Format) packages text, fonts, and graphics so a document looks consistent across devices and printers.
PDFs can contain text layers, images, vector graphics, and interactive form fields.
Some PDFs are scanned images without selectable text — those need OCR for Word-style editing.
Converting PDF pages to images rasterizes each page; converting images to PDF wraps them into a document container.
