Frequently Asked Questions
Are my sensitive PDF documents uploaded to a cloud server?
No! The compression engine runs 100% inside your web browser using PDF-lib. Your confidential contracts, financial statements, and personal records never leave your device.
How does browser-based PDF compression work?
Our tool restructures the internal PDF cross-reference table into compressed object streams and strips redundant document metadata, fonts, and unreferenced objects to minimize file size.
Will compressing a PDF alter its visual formatting or fonts?
No. Page layouts, typography, vector lines, and embedded text remain pixel-perfect.
Is there a maximum PDF file size or daily limit?
There are no artificial limits or daily paywalls. You can compress as many PDFs as your device's memory allows.
