Available in the Full App
Mass PDF manipulation is available exclusively inside our logged-in dashboard to ensure the highest level of security and document privacy.
Built for document workflows
Every page, one pass
Upload up to 20 PDFs per batch call and get a ZIP back, or fire thousands of API calls in parallel. Each document is stamped on every page without flattening the text layer.
Per-recipient stamps
Dynamic variables like {date}, {filename}, and {n} resolve per document — or burn the recipient's email into every page from the API for a built-in audit trail.
Searchable output
The watermark is added as a proper PDF layer, not a rasterized page image — text stays selectable and searchable, and file sizes stay sane.
Who bulk-watermarks PDFs?
Law firms stamp "CONFIDENTIAL" across discovery sets before sharing them. Publishers protect ebook review copies with the reviewer's name. Finance teams mark quarterly reports as drafts until sign-off. Course platforms personalize worksheets per student. If you've ever opened the same watermark dialog fifty times in a desktop PDF editor, this replaces that afternoon with one batch upload — identical placement, every document, every page.
Common questions
Does it work on scanned PDFs? Yes — the stamp is overlaid on each page regardless of whether the page is text or a scan. What does it cost? Each PDF is 1 credit, batches included, and failed documents are never billed. Can I try it on one file first? Yes — the free PDF tool handles single documents without an account.
