Keep an original backup
Work from a copy when the source document is important. Encryption and access control do not replace a verified backup.

Before you protect important documents
Choose a strong, memorable password
Use a password that is difficult to guess and store it separately from the protected file.
Prepare the destination folder
Select a location with enough free space and a clear file name so the protected output is easy to identify.
Plan how the password will be delivered
Send the password through a different communication channel instead of placing it beside the protected attachment.
Step-by-step PDF and Office file protection
1. Add the files you want to protect
Start by building the document list that will be processed in this protection task.
1Open GiliSoft PDF DOC Password Protect.
2Add the PDF, Word, Excel, PowerPoint, WPS, image, or supported media files you need.
3Review the list and remove anything that should remain unprotected.
4Continue to the password and destination settings.
Set and confirm the password
Enable password protection, enter the password carefully, and confirm it. Avoid short passwords, reused passwords, and information that recipients can easily guess.
Choose the output destination
Select a folder for the protected result. Keep protected files separate from the ordinary source documents to prevent sending the wrong version.
Create and test the protected file
Start the protection task, wait for completion, then open the result and verify that the correct password is required before delivery.
Do not delete the original document until the protected output has been opened, checked, and backed up successfully.
Final document delivery checklist
Open the finished output
Confirm that the protected file opens normally after the correct password is entered.
Test the wrong password
Verify that an incorrect password does not expose the protected content.
Check the destination and file name
Make sure the recipient can identify the protected version without confusing it with the source.
Send the password separately
Use a separate message, call, or approved password-sharing channel.

PDF DOC Password Protect FAQ
Which file types can I protect?
The product page lists PDF, Word, Excel, PowerPoint, WPS, image, MP4, and other supported files. Confirm the current application list before a large batch.
Can I recover a forgotten password?
Do not assume an encrypted document can be recovered without its password. Keep secure password and backup records before delivery.
Should I email the password with the file?
No. Send the protected file and its password through separate channels whenever practical.
When should I use PDF DRM instead?
Choose DRM when the job requires licensing, device binding, authorization changes, or stronger control after delivery.
