Protect PDF online

What Protect PDF does

Protect PDF applies standard PDF encryption and selected print or edit permissions to a newly saved copy.

Protect PDF runs as a queued server job after the source upload completes. The generated artifact receives a separate download link, so the original device file remains unchanged.

How to use this tool

Prepare the source
Create a strong unique password and plan a separate secure channel for sharing it. This preparation matters specifically before using Protect PDF.
Upload and inspect
Select one unencrypted PDF and a new password, wait for the Protect PDF upload to finish, and confirm that the displayed source is the intended file.
Choose the available options
Set only the Protect PDF controls needed for this output and review required fields before starting the job.
Download and verify
Test the output in a second viewer with the correct and an incorrect password before sending it. Keep the source until the Protect PDF result has passed that review.

Common use cases

Prepare a delivery copy

Use Protect PDF to create a separate copy for a recipient without overwriting the maintained source.

Correct one document workflow

Apply Protect PDF to a known document problem after confirming the operation matches the intended outcome.

Create a review candidate

Generate a Protect PDF result that can be checked before it enters a records, publishing, or sharing process.

Supported inputs

one unencrypted PDF and a new password
One Protect PDF job at a time through the current public workspace

Output

One AES-encrypted PDF protected by the supplied open password.

Limitations to know

PDF permission flags depend on viewer enforcement, and password protection cannot prevent an authorized viewer from reproducing visible information.
Protect PDF cannot reconstruct source information that is absent, damaged, or inaccessible in the uploaded document.
Viewer, font, image, form, signature, and accessibility behavior can change after Protect PDF; compare important output with the source.
No Protect PDF result should be treated as legal, archival, accessibility, or compliance certification without the required independent review.

Privacy and document handling

Protect PDF uploads the selected source to configured object storage so the worker can process it.
The worker attempts to remove temporary Protect PDF workspace files after the job, which is separate from stored input and output retention.
Avoid using Protect PDF with confidential material unless the published storage and retention information is suitable for the document.

Stored input and output objects are deleted automatically: files uploaded without an account are removed about 24 hours after upload, and files belonging to a signed-in account are removed after 7 days. A scheduled sweep enforces this hourly against the object store itself. Workers attempt to remove per-job temporary directories after processing. This does not delete stored input or output objects.

Read the Privacy Policy and Security page for verified implementation details and open questions.

Troubleshooting

Protect PDF cannot start

Confirm the expected one unencrypted PDF and a new password finished uploading and every required Protect PDF option contains a valid value.

Protect PDF reports a processing error

Open the source locally, remove unsupported encryption where authorized, and retry Protect PDF with a smaller valid file.

Protect PDF output is not suitable

Test the output in a second viewer with the correct and an incorrect password before sending it. If it still differs, retain the source and use a workflow designed for that document feature.

Frequently asked questions

Does Protect PDF replace my original file?

No. Protect PDF creates a separate stored output and does not edit the source on your device.

Is every Protect PDF result guaranteed to look identical?

No. Protect PDF depends on the source structure and processing engine, so important pages and features must be checked.

Should I delete my source after Protect PDF?

No. Keep the source until the Protect PDF output has been opened, compared, and accepted for its intended use.

How should I check my Protect PDF result?

Open every Protect PDF download and compare it with the unchanged source before sharing or deleting anything. Pay particular attention to this documented limitation: PDF permission flags depend on viewer enforcement, and password protection cannot prevent an authorized viewer from reproducing visible information.
