OPENING PASSWORD
Create an unlocked copy from one PDF
Enter the known, non-empty opening password for one PDF. Use only a password you may use, then check the downloaded result before using it.
- One PDF per operation
- Known, non-empty opening password
- Input and output: up to 50 MB each
The file state determines the returned copy
The operation uses the opening password entered in the tool. Its result depends on whether the selected PDF is encrypted.
Encrypted PDF
When the password is correct and the encryption method is compatible, an unlocked download copy is created.
Unencrypted PDF
A PDF without encryption is returned as a copy. It is not changed by the operation.
Incorrect password
If the opening password is incorrect, the tool shows an error instead of creating a result.
Provide the file, password, then review
There is one PDF and one known opening password in each operation. Keep the password available until the result has been checked.
