When a tool like TheBestPDF does not properly encrypt documents, its reliability depends on how it manages security and whether it delivers on what it claims.
Encryption is key to protecting PDFs with legal information, and its absence can expose sensitive data.
To assess if it’s reliable in your case:
Run a test with a sample PDF: apply encryption in TheBestPDF and check if it requires a password when opened in other viewers (Adobe Acrobat, Foxit, browser).
Review its security policy on the website and see if they specify the type of encryption used (AES-128, AES-256, etc.).
If you handle legal or sensitive documents, consider tools with a proven reputation for encryption, and only use TheBestPDF for low-risk tasks if their response is unclear.
The final decision will depend on how critical security is for your use and on the company’s transparency.
