Add Watermark online

What Add Watermark does

Add Watermark appends a text layer using the selected position, font size, and opacity without replacing source page content.

Add Watermark 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
Choose short ASCII text and an opacity that remains readable without obscuring the document. This preparation matters specifically before using Add Watermark.
Upload and inspect
Select one PDF document, wait for the Add Watermark upload to finish, and confirm that the displayed source is the intended file.
Choose the available options
Set only the Add Watermark controls needed for this output and review required fields before starting the job.
Download and verify
Inspect light and dark pages, rotated pages, and small page sizes for readability and overlap. Keep the source until the Add Watermark result has passed that review.

Common use cases

Supported inputs

one PDF document
One Add Watermark job at a time through the current public workspace

Output

One PDF with the selected text watermark drawn on every page.

Limitations to know

A visible watermark is not access control, ownership proof, copy prevention, or secure redaction.
Add Watermark 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 Add Watermark; compare important output with the source.
No Add Watermark result should be treated as legal, archival, accessibility, or compliance certification without the required independent review.

Privacy and document handling

Add Watermark uploads the selected source to configured object storage so the worker can process it.
The worker attempts to remove temporary Add Watermark workspace files after the job, which is separate from stored input and output retention.
Avoid using Add Watermark 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

Add Watermark cannot start

Confirm the expected one PDF document finished uploading and every required Add Watermark option contains a valid value.

Add Watermark reports a processing error

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

Add Watermark output is not suitable

Inspect light and dark pages, rotated pages, and small page sizes for readability and overlap. If it still differs, retain the source and use a workflow designed for that document feature.

Frequently asked questions

Does Add Watermark replace my original file?

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

Is every Add Watermark result guaranteed to look identical?

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

Should I delete my source after Add Watermark?

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

How should I check my Add Watermark result?

Open every Add Watermark download and compare it with the unchanged source before sharing or deleting anything. Pay particular attention to this documented limitation: A visible watermark is not access control, ownership proof, copy prevention, or secure redaction.
