Do it now
No watermark, no feature locked behind the price, no account. The free ceiling is quantity only: 20 files and 60 pages. $19 once removes it permanently.
Open the tool. Nothing to install, no account, no email.
Drag in up to 20 PDFs (60 pages total on the free tier). Set the prefix and the start number.
Run it. The output is written to a folder you pick, or a ZIP.
Check the network panel while it runs if you want to confirm the claim rather than take it — or switch the network off first.
How it actually works
What "free" usually costs on a legal document
Almost every free online PDF stamper works the same way: your file is uploaded to a server, processed there, and held for some retention window described in a privacy policy you did not read. For a holiday photo that is a fair trade. For a document under a protective order it is a disclosure to a third party, made by you, in exchange for saving four minutes — and it is the kind of thing that is very hard to explain afterwards.
The second cost is the output. Free stampers overwhelmingly burn the number in as a bitmap, so it cannot be found with Ctrl+F and a review platform cannot index it. Here the number is drawn as a text object using the PDF standard-14 fonts, which also means no embedded font bytes are added to the file.
Where the free tier actually stops
Twenty files and sixty pages, and that is the only limit. Continuous sequencing, reserved thousands, used-range checks, confidentiality legends, exhibit labels, per-page placement against crop box and rotation, output verification, the manifest CSV with SHA-256, the .dat and .opt load files, the metadata check and the redaction check are all on before you pay anything.
That shape is deliberate. A trial that removes features cannot tell you whether the tool is right, because everything that makes this worth $19 — one sequence across a set, proof of what was written, checks over the whole batch — is invisible on a single document. A quantity cap lets you test the real job on a real, small set.
How to verify the no-upload claim in about thirty seconds
Open your browser’s developer tools, go to the network panel, drop in a file and run the batch. Nothing goes out. Then do the stronger version: load the page, turn off your Wi-Fi, and run a batch anyway. It finishes. A tool that needed a server could not do that, and no privacy policy is worth as much as watching it work offline.
The one network request that does exist is license validation, and only after you enter a key. The documents are never part of it.
When you should not use a browser tool for this
If the set is measured in gigabytes, your machine’s memory is the ceiling and a desktop or server tool will be a better fit. If several people need to work the same production, with review, redaction workflow and an audit trail across a team, that is a platform, not a stamper. And if your obligation is to produce in a specific vendor’s native format, check that format first.
For the ordinary case — one person, a set of dozens to hundreds of documents, a deadline this week — the browser is the fastest correct answer available, and the one that keeps the files where they already are.
