GOOD TO KNOW
A linearized PDF is stored so it can be shown page by page while it downloads.
| QUESTION | ANSWER | WHY IT MATTERS |
|---|---|---|
| What changes? | The order of the data inside the file | The first page can be shown straight away |
| Does it look different? | No. Pages, text and links are the same | There’s nothing to check afterwards |
| Is the file smaller? | Not much, and sometimes a little larger | Use Compress PDF to cut the size |
| Who benefits? | People opening the PDF from a link | Most of all on slow connections |
