[ENCRYPT & DECRYPT WORD DOCUMENTS]

Two different problems wear the same name — this page sorts out which one you have.

"Decrypt a Word document" means one of two completely different things, and the right answer depends entirely on which you are facing:

  • Word asks for a password when you open the file. The encryption is inside the .docx, applied by Word itself. This tool cannot help — see the section below.
  • You have a .enc file that contains a Word document. It was encrypted here as a file. The tool below opens it.

[IF WORD ASKS FOR A PASSWORD WHEN OPENING]

That password was set inside the document via Word's own encryption, which since Office 2007 has been AES-based and is genuinely strong. No online tool can strip it, and any site claiming to remove Office passwords instantly is either guessing common passwords or misrepresenting what it does.

With the password, removing it takes a few seconds in Word:

  1. Open the document and enter the password
  2. File → Info → Protect Document → Encrypt with Password
  3. Clear the password field and press OK
  4. Save

Without the password, the document is not recoverable in any practical sense. Check your password manager and browser saved passwords, ask whoever sent it, or look for an earlier unprotected copy in your cloud storage version history.

One exception worth knowing: "Restrict Editing" is not encryption. If the document opens fine but will not let you edit it, that is a flag rather than a cipher, and Word's Review → Restrict Editing → Stop Protection removes it.

[ENCRYPTING A WORD DOCUMENT WITH THIS TOOL]

What this tool does is encrypt the file — the whole .docx becomes an unreadable .enc file that reveals nothing, not even that it is a Word document. That is a different and often better protection than Word's built-in password.

Reasons to prefer it:

  • The filename and file type are hidden, since the original name is stored inside the encrypted file
  • You can use a random 256-bit key rather than a memorable password
  • An HMAC-SHA256 tag detects tampering, which Word's format does not surface to you
  • It works the same for .doc, .docx, .xlsx, .pptx and anything else

The trade-off: the recipient decrypts here rather than opening it directly in Word. For sending something sensitive by email, that is usually the point.

[WHICH PROTECTION SHOULD YOU USE?]

Situation Use
Recipient must open it directly in WordWord's built-in password
Sending it through email or chat you do not trustFile encryption (this tool)
The filename itself is sensitiveFile encryption — Word leaves the name visible
Archiving several documents together7-Zip with AES-256, or encrypt a ZIP here
You want a random key rather than a passwordFile encryption — Word only accepts passwords

[HOW TO ENCRYPT OR DECRYPT A WORD DOCUMENT]

Encrypt a Word document as a file, or remove a password Word itself applied.

  1. Work out which protection you are facing. If Word prompts for a password on opening, the encryption is inside the document. If you have a .enc file, it was encrypted as a file and the tool on this page opens it.
  2. For a Word-applied password. Open the document in Word with the password, then go to File, Info, Protect Document, Encrypt with Password, clear the field and save. No online tool can do this for you.
  3. To encrypt the document as a file. Select the .docx with the tool on this page, choose a password or random key, and download the encrypted .enc file.
  4. To decrypt a .enc containing a document. Select the .enc file, enter the password or key, and the original document downloads under its original filename.

[FREQUENTLY ASKED QUESTIONS]

How do I decrypt a Word document online?

If the file is a .enc produced by this site, use the tool on this page with the password or key. If Word itself prompts for a password, no online tool can decrypt it — that encryption lives inside the .docx and is removed in Word via File, Info, Protect Document, Encrypt with Password.

Can I remove a Word password without knowing it?

No. Office has used AES-based encryption since 2007 and it has no practical bypass. Services claiming instant Office password removal are attempting to guess common passwords, which only works against weak ones. Check your password manager or ask the sender instead.

What is the difference between Word encryption and file encryption?

Word encrypts the contents inside the .docx, so the file still looks like a Word document and its name stays visible. File encryption turns the whole document into an opaque .enc file that reveals nothing about its type, name or contents. Word encryption is more convenient for the recipient; file encryption hides more.

Does this work for Excel and PowerPoint too?

Yes. File encryption operates on raw bytes, so .xlsx, .pptx, .doc, .xls and .ppt are all handled identically. The same applies to their password protection — those are removed in the respective Office application, not here.

My document opens but will not let me edit it. Is it encrypted?

No. That is "Restrict Editing", which is a flag rather than encryption — the contents were never scrambled. Remove it in Word under Review, Restrict Editing, Stop Protection. You may need the password that was set, but the document itself is not encrypted.
