High Performance PDF Encryptor

Managing documents in the modern digital world can often be complicated and tedious. However, thanks to our Encrypt PDF tool, you can perform all these security operations directly from your browser without downloading any program. Sharing sensitive information digitally poses serious risks. With our security tools, you can set impenetrable passwords on your documents, prevent unauthorized copies or add your own digital watermark. We know how valuable your time is to you; Therefore, our transactions are completed within seconds on our private cloud servers. To completely remove locks or ease permission restrictions on your encrypted documents later, our Unlock PDF tool is ready at any time.

Maximum Data Security Guarantee

No need to worry when processing your files online. Your files are protected with 256-bit AES encryption algorithms as soon as they are uploaded to the system. We strictly adhere to GDPR (European Data Protection Regulation) and KVKK rules. All your PDF documents and new files created will be permanently deleted from our servers exactly 2 hours after the process is completed.

Why Should Pdfoni Be Preferred?

Unlike desktop software, our system works independently of your Windows, Mac, Linux or smartphones. You can successfully encrypt PDF wherever you are with just an internet connection. The original resolution and quality of your document is fully preserved.
