Does this shrink the PDF?

Not always. Linearizing changes how the file is arranged so a browser can show the first page sooner. The file size is often similar.

Will the pages look different?

No. The content stays the same. Readers that support fast web view can start sooner.

When should I use this?

Before you host a PDF on a site or send a large report that people will open in a browser tab.

Make a PDF open faster online

A big PDF can sit on a spinner until the whole file arrives. This page makes a PDF open faster by preparing it for “fast web view” (linearization).

How to linearize a PDF

Upload a PDF up to 80 MB.
Press Convert file.
Download the prepared PDF and share that copy.

What you get

The same document, arranged so the start of the file is enough to show the first pages. Text, images, and page count stay the same.

When it is worth it

Reports you link from a website
Large slide-style PDFs people open on a phone
Anything you are tired of watching “load” in a browser

It is not a compressor and it is not a repair tool. If the PDF is already small, you may not notice a change.
