❓ FAQs
How much can I compress a PDF?
Compression results vary based on your PDF content. Typically, you can reduce file size by 40-70% while maintaining good quality. PDFs with many images compress more than text-only documents.
Will compression affect PDF quality?
Our compression algorithm balances file size reduction with quality retention. You can choose between low, medium, and high compression levels based on your needs.
Can I compress password-protected PDFs?
No, password-protected or encrypted PDFs must be unlocked before compression. You can remove the password first, compress the file, and then re-apply protection if needed.
Is there a file size limit?
You can compress PDF files up to 100MB. If your file is larger, try splitting it into smaller parts first.
