Everything you need to know about protecting multiple PDF files at once with PDF Lab's free batch protection tool
Go to Batch Protect PDF ToolThe Batch Protect PDF tool adds the same opening password to several PDFs in one go. It saves time when you need to secure a set of related documents, such as monthly reports or client contracts.
Yes. The password you enter is applied to every PDF in the batch. If each file needs a different password, protect them one at a time with Protect PDF.
Each PDF is encrypted with 256-bit AES, the strongest encryption in the PDF standard. The real strength comes from your password, so use 12 or more characters mixing letters, numbers and symbols.
Batch Protect sets an opening password only. To restrict printing, copying, editing or form filling, use Protect PDF, which offers these permissions for each file.
For the smoothest experience, protect up to about 20 PDFs per batch. For more files, run several batches.
When the batch finishes, download each protected PDF on its own or all of them together as a ZIP. Each file keeps its original name.
Not directly. Remove the existing password first with Unlock PDF (you need to know it), then protect the files again.
We cannot recover it, because we never store passwords. Keep the password somewhere safe, and keep your original files so you can protect them again if needed. Send the password separately from the files, for example by phone.
Yes. It works in modern browsers on Android phones, iPhones and tablets. Large batches upload faster on Wi-Fi.
Your PDFs are uploaded over an encrypted connection and protected on our own server. They are kept only temporarily so you can download the results, then deleted automatically. Your password is used only to encrypt the files and is never stored. Nothing is sent to a third party.
