Optimize a PDF for fast web viewing
This tool linearizes a PDF (also called 'Fast Web View') so browsers can start displaying the first page before the whole file has downloaded. It restructures the file with qpdf on our server without changing its content.
When to use it
- Speed up a large PDF you host on your website.
- Improve the experience of opening a PDF over a slow connection.
- Prepare a PDF for embedding in a web page.
Private & secure
Your file is uploaded over an encrypted HTTPS connection, converted on our server and streamed straight back to your device. Each request runs in its own isolated workspace that is deleted the instant the result is returned, so nothing is ever stored or shared.
Frequently Asked Questions
What does linearizing actually do?
It reorganises the PDF's internal structure so a viewer can render page one while the rest streams in, instead of waiting for the entire download.
Does it change how my PDF looks?
No. The content is untouched — only the internal byte order is optimised for streaming.
Are my files uploaded to a server?
Yes. Unlike our browser-based tools, the Optimize PDF for Web runs on our secure server because it needs professional desktop-grade software to do the job well. Your file is processed in an isolated workspace and deleted automatically the moment the result is sent back — nothing is stored, logged or shared.
Is it free? Is there a watermark or size limit?
It is completely free with no sign-up and no watermark. Files up to 100 MB are supported per conversion.
