66.10 PDF Linearize for Fast Web

20200526

Linearizing a pdf file results in a fast web view of the file. That is, the pdf will be streamed within a browser so that the first page will be displayed whilst the remaining pages are downloaded. For a non-linearized pdf the file will need to be fully downloaded before being viewed.

Use qpdf to linearize a pdf file.

$ qpdf --linearize mydoc.pdf faster.pdf

To check if the PDF is linearized by this method try checking the 4th line of the pdf file:

$ sed '4q;d' faster.pdf
