How is Optimize PDF for Web different from Compress PDF?

Prepare a PDF for Faster Web Viewing
Optimize PDF for Web rewrites a PDF for fast web view when possible. The audience is documents headed for a website, help center, knowledge base, client portal, product page or public download area where people may open the file in a browser.
What Web Optimization Means
A web-optimized PDF is often called a linearized PDF. The file is arranged so supported PDF readers can start showing the first page before the entire file has downloaded. That can make long manuals, catalogs, reports and guides feel quicker to open for people on slower connections.
Different from Compress PDF
Compress PDF focuses on reducing file size. Optimize PDF for Web focuses on file structure. The output may be smaller, similar in size or sometimes a little larger. Use Compress PDF when the main problem is attachment size. Use Optimize PDF for Web when the document is meant to be read online.
Best Documents to Optimize
Good candidates include product manuals, menus, brochures, policy documents, public reports, documentation, course materials and downloadable guides. If a PDF is linked from a page and users open it directly in the browser, fast web view is worth trying.
How to Check the Result
After downloading, open the optimized PDF and confirm that pages, links, bookmarks and images still behave as expected. Then upload it to the place where readers will access it. If you are maintaining a website library, combine this with clear file names and reasonable file sizes for a better reading experience.

Frequently Asked Questions
What is a linearized PDF?
A linearized PDF is arranged for fast web view. It can help the first page appear before the entire file finishes downloading in supported PDF readers.

No. The output may be smaller, similar in size or sometimes a little larger. The main goal is web viewing behavior, not file size reduction.
When should I use Optimize PDF for Web?
Use it for PDFs that will be hosted on a website, help center, client portal or public download page. Manuals, guides, reports and menus are common examples.
How can I check if the PDF still opens correctly?
Open the output in a PDF reader and check pages, links, images and bookmarks if they matter. Then test the file from the place where readers will access it.
