PDF Security
Inspect encryption and permissions locally, without applying or removing them.
PDF security has two halves that are often confused. Encryption genuinely protects content: without the key the bytes cannot be read. Permission flags are different — they are requests recorded in the file asking a viewer to disallow printing or copying, and a viewer is free to ignore them. Knowing which one a document actually relies on is the difference between real protection and a false sense of it, so these tools report both precisely.
All PDF security tools
PDF Encryption Checker
One question, answered exactly: what encryption does this file use?
PDF Permissions Checker
Read the permission bits a PDF sets — and what they are really worth.
PDF Security Inspector
Every security-relevant feature of a document, inventoried in one pass.
PDF Security Analyzer
Not just what is in the file — which parts of it are a problem.
PDF Metadata Viewer
Read the fields a PDF carries about itself, including the raw XMP.
PDF Metadata Remover
Clear selected document properties before sharing; this is not secure anonymisation.
Edit PDF Metadata
Set a document’s properties deliberately instead of inheriting them.
PDF Signature Inspector
Find out whether a signed PDF is cryptographically signed or just drawn on.
About PDF security
Is my password sent anywhere?
The published security inspectors do not ask for a password. They inspect the declared encryption and permission settings locally without decrypting the content. Password-protection and password-removal tools are not implemented and remain drafts, so no encryption or decryption operation is offered here. To apply or remove encryption, use a trusted local PDF application rather than entering a password on this site.
Can you remove a password I do not know?
No. This site cannot remove PDF encryption, even when you know the password, and it has no password-cracking or brute-force functionality. If you are authorised to unlock the document and have the correct password, use a trusted desktop PDF application or qpdf locally. If you do not know the password, ask the document owner for access or an unencrypted copy.
