Frequently Asked Questions
How much can I compress a PDF?
Typically 50-80% size reduction for image-heavy PDFs. Text-only PDFs see less reduction (10-30%). Use "Maximum" for smallest files, "Balanced" for quality/size tradeoff.
Does compression affect text quality?
Text remains sharp and searchable. Compression primarily reduces image quality within the PDF. At "Balanced" settings, the difference is barely noticeable.
