Frequently Asked Questions
Is this as good as Adobe Acrobat Pro's compression?
For the vast majority of PDFs – yes. We achieve up to 90% size reduction with no noticeable quality loss. Acrobat Pro offers advanced controls (like downsampling to specific DPI), but our automatic algorithm matches Acrobat's 'High Quality' preset.
Do I need to have Adobe Acrobat installed?

Can I compress a PDF that was created with Acrobat?
Absolutely. Any standard PDF – created by Acrobat, Word, Google Docs, or scanners – works perfectly.
Will digital signatures from Acrobat be preserved?
Yes. We preserve all digital signatures, certification information, and form fields. Your signed documents remain valid.
Is there a file size limit compared to Acrobat?
Acrobat Pro can handle larger files locally, but our 100 MB limit covers most users. For files over 100 MB, you can split them or contact us.
