In today’s digital age, privacy and data security are more important than ever. Whether you’re a business owner, a freelancer, or a student, you often share PDF files containing sensitive information—contracts, invoices, ID proofs, or academic records. But how do you ensure these files stay private and protected?
The answer is simple: encrypt your PDFs before sharing and decrypt them only when needed. Our online PDF encryption and decryption tool makes this process fast, free, and accessible—no technical skills or signup required.
