Frequently Asked Questions

Why use Zaeyon PDF Tools instead of iLovePDF or Smallpdf?

Most PDF websites upload your sensitive files to cloud servers. Zaeyon processes all PDF files 100% locally inside your web browser using WebAssembly. Your files never leave your device, ensuring total privacy and instantaneous processing with no file size caps or daily quotas.

Are all PDF tools free to use?

Yes, every PDF tool on Zaeyon is 100% free with no subscriptions, sign-ups, or watermarks.

Can I use these PDF tools on mobile devices?

Yes! All tools are fully responsive and work on iPhone, iPad, Android, Mac, Windows, and Linux browsers.
