How Protection and Watermark Tools Work
Understand add watermark, remove watermark, unlock PDF, protect PDF, and metadata review workflows.
Watermark and metadata workflows
The new watermark and metadata tools are built for review copies, ownership labels, audits, and document handoff checks.
They help you inspect what the file contains and add or reduce simple repeated text marks when that fits the workflow.
Unlocking and protection modes
Unlock PDF uses the current password to open the file and export a flattened share copy.
Protect PDF adds password protection and can restrict printing, copying, and editing. This operation is processed on PDFCustom servers, while most other tools run in your browser.
When to review the result manually
If the PDF contains complex visual overlays or unusual permissions, always review the output before sending it onward.
That extra check is especially important for legal, financial, and customer-facing documents.
