Frequently asked questions

What is PDF linearization?

Linearized PDFs load page-by-page in web browsers instead of requiring the entire file to download first. This makes web viewing much faster.

Does optimization reduce file size?

Linearization reorganizes the file structure for web delivery but doesn't significantly reduce size. Use the compress tool for file size reduction.

When should I optimize a PDF?

Optimize PDFs that will be viewed online — on websites, in web apps, or shared via links. It dramatically improves loading speed for large documents.

Does optimization affect print quality?

No. The visual content and quality are identical. Only the internal file structure is reorganized for faster streaming.
