Why Protect Your PDF Files?
Password protecting a PDF ensures only authorized people can open your document. Whether you’re sharing a business contract, student certificates, medical records, or confidential reports – PDF protection adds a critical layer of security. Our tool uses 128-bit encryption to keep your files safe.
What Do PDF Permissions Mean?
When you protect a PDF, you don’t just add a password – you also control what the recipient can do after opening the file. Here’s what each permission means:
🖨️ Allow Printing When enabled, the recipient can print the PDF after entering the password. Disable this if you want to share a document for viewing only — preventing physical copies from being made.
📋 Allow Copying When enabled, the recipient can select and copy text or images from the PDF. Disable this to protect your content from being copied into other documents or used without permission.
✏️ Allow Editing When enabled, the recipient can make changes to the PDF content. Disable this to ensure your document — whether a certificate, contract, or report — cannot be altered by anyone.
💡 Tip: For maximum protection, disable all three permissions. The recipient can still read the document after entering the password, but cannot print, copy, or edit it.

Who Should Use This Tool & Why Protect PDF?
Whether you’re a student, professional, or business owner — there are many situations where protecting a PDF becomes essential:
🎓 Students & Teachers Share assignment papers, question papers, or study materials without allowing others to copy or edit the content. Protect certificates and mark sheets before sending them via email or WhatsApp.
💼 Business Professionals Send contracts, proposals, invoices, and NDAs with password protection — ensuring only the intended recipient can open the document. Restrict printing and copying to prevent unauthorised use of confidential business information.
🏥 Medical & Legal Professionals Medical reports, prescriptions, legal agreements, and court documents contain highly sensitive information. Password protecting these PDFs ensures privacy and compliance before sharing with clients or colleagues.
🏦 Finance & Banking Salary slips, bank statements, tax returns, and financial reports should always be protected before sharing — even with trusted parties. A password adds an extra layer of security in case the file is forwarded accidentally.
📸 Freelancers & Creators Protect your portfolio, proposals, pricing documents, and creative work from being copied or redistributed without your permission.
🔒 Bottom Line: Any PDF containing personal, financial, legal, or confidential information should be password protected before sharing — regardless of who you’re sending it to.
