Add password protection to any PDF so only authorized people can open it. Essential for sharing sensitive documents like contracts, financial records, medical information, and legal paperwork.
Upload your PDF, enter a password, and click "Protect." The tool renders each page and creates a new encrypted PDF that requires the password to open. Print permission is allowed by default.
Most online PDF tools — including iLovePDF, SmallPDF, and Adobe Acrobat online — upload your files to their servers for processing. That means your contracts, tax documents, medical records, and confidential business files pass through a third party's infrastructure. FixMyPDF.ai is different: every tool runs entirely in your web browser using client-side JavaScript. Your files are never uploaded, never stored on a server, and never accessible to anyone but you. There is no backend server processing your documents — it all happens on your device.
Can I remove the password later? Yes — use our Unlock PDF tool with the same password to remove protection.
How strong is the encryption? The PDF is encrypted using the jsPDF encryption standard. For enterprise-grade encryption, consider dedicated PDF software.
