Frequently Asked Questions

Will compressing my PDF affect text quality?

Text and vector graphics in PDFs are not affected by compression — only embedded images are re-encoded. Your text will remain perfectly sharp and copyable.

Can I compress password-protected PDFs?

Password-protected PDFs cannot be compressed without first unlocking them, as the content is encrypted. Remove password protection in Adobe Acrobat or your PDF viewer before compressing.

What is the maximum PDF size I can compress?

Since compression runs in your browser, the limit depends on your device's RAM. Most devices handle PDFs up to 50MB without issues. Very large PDFs (100MB+) may perform better with a desktop PDF editor.
