Why PDFStrix is Safer Than Other Web PDF Tools

Most online PDF converters upload your confidential bank statements, tax forms, and contracts to remote servers. PDFStrix is fundamentally different.

Got Questions? We've Got Answers

Are my PDF files uploaded or stored on any server? expand_more

Absolutely not. All operations run 100% client-side in your web browser. Neither VA Developers nor any third party ever receives, stores, or inspects your files.

Is PDFStrix really free to use? expand_more

Yes! PDFStrix is completely free with no hidden paywalls, no limits on number of tasks, and no annoying watermarks stamped onto your output documents.

Can I convert Word documents to PDF and vice versa? expand_more

Yes. PDFStrix supports full bidirectional conversions between PDF and Microsoft Word (.docx) formats with font and paragraph layout reconstruction.

How does PDF password protection and unlocking work? expand_more

Password protection encrypts your document using standard cryptographic handlers so that viewers must enter your designated password to view it. Unlocking allows authorized document owners to remove password restrictions by confirming the existing password.
