Frequently asked questions about PDF optimization
Everything you need to know about PDF optimization
What is the difference between optimizing and compressing?
Compressing reduces the file size. Optimizing improves the structure: web-optimized PDFs load faster in the browser, print-optimized ones have embedded fonts.
What does web-optimized mean?
Web-optimized (linearized) PDFs can be loaded page by page. The user sees the first page immediately while the rest is still loading.
When do I need print optimization?
When you send PDFs to a print shop. All fonts are embedded so the print result looks identical everywhere.
What is prepress?
Prepress is the highest quality level for professional printing. Colors remain unchanged and all fonts are fully embedded.
Does the file become larger?
Web optimization can actually make the file smaller. Print/prepress may slightly increase the size because all fonts are embedded.
