FAQ
Common questions from students.
How does Docula compress PDFs?+
Docula attempts browser-side PDF optimization. If a safe smaller output is not possible, it keeps quality stable and explains the result.
Will compression reduce PDF quality?+
Docula avoids unexpected quality reduction. Use high quality for conservative processing or maximum compression when file size matters more.
Why did my PDF not get much smaller?+
Some PDFs are already optimized or contain images that cannot be reduced safely without heavier processing.
Can I use compressed PDFs with AI study tools?+
Yes. After compression, continue to PDF Chat, PDF to Study Notes, Flashcards, Quiz Generator, or AI Study Coach.
