PDF documents frequently contain sensitive information — salary slips, medical reports, legal contracts, government certificates, and confidential business proposals. Sharing unprotected PDFs over email, WhatsApp, or cloud storage exposes these files to unauthorized access. Adding a password layer ensures that only authorized recipients can open, view, and interact with the document. GS DocSeva's browser-based PDF protector lets you apply AES-128 encryption in seconds without uploading your file anywhere — your data stays exclusively on your device at all times.
Unlike cloud-based PDF tools that process files on remote servers, GS DocSeva uses pdf-lib — a powerful open-source JavaScript library — to encrypt your PDF entirely within your browser's local memory. The encrypted output is streamed directly to your download folder, meaning no third-party server ever touches your confidential document.
Protect admit cards, marksheets, category certificates, and identity proof PDFs before sharing with recruitment portals or agents.
Secure sensitive NDAs, financial statements, tender documents, and employee records with individual access passwords.
Encrypt prescription PDFs, lab reports, and health records before storing on cloud drives or sharing with healthcare providers.
Password-protect degree certificates, mark sheets, and research papers to prevent unauthorized sharing or misuse.
PDF encryption operates on two distinct password layers defined in the ISO 32000 PDF specification. The User Password (also called the Open Password) controls who can open and view the document — without it, the PDF appears as an unreadable encrypted binary. The Owner Password (also called the Permissions Password) controls what an authorized viewer can do: printing, copying text, editing content, and adding annotations can all be individually restricted.
GS DocSeva applies AES-128 bit encryption — the same standard used by financial institutions and government portals. This means your document is protected by over 340 undecillion possible key combinations, making brute-force attacks computationally infeasible under normal circumstances.

⚡ Pro Tip: Use a combination of uppercase letters, numbers, and symbols for maximum password strength. Avoid dictionary words or personal information like birthdays.
No. All encryption runs entirely inside your browser using pdf-lib. Your document never leaves your device or touches any external server.
AES-128 bit encryption per the PDF 1.7 ISO specification — compatible with Adobe Acrobat, Foxit, and all major PDF readers.
Yes. The tool is fully responsive and works on Android Chrome, iOS Safari, and all modern mobile browsers with no app installation needed.
Since processing is 100% local and no data is stored, we cannot recover forgotten passwords. Always save your password in a secure manager before applying protection.
