Sign PDF — Free, No Card Required

No account is required and no email address is collected. You are never asked to register before downloading, and there is no verification step standing between finishing the job and getting the file.

There is no watermark, no branding and no metadata added to the output. The file you download contains your content and nothing else — nobody receiving it can tell what produced it.

There is no usage cap. You can run the tool once or fifty times in an afternoon, and nothing changes on the fiftieth run. There is no queue that free users wait in, no artificial slow-down, and no premium tier that gets a faster version of the same tool.

The honest caveat is that free tools are typically focused rather than exhaustive. This one does its job properly and stops there. If you need document redaction, PDF/A conformance checking or batch scripting across thousands of files, professional software genuinely earns its licence fee — this is not trying to replace it.

The document is loaded with pdf-lib and Helvetica Oblique is embedded. The tool measures the width of your name at the chosen point size, positions it so it sits inset from the right edge of the page with a guaranteed minimum left margin, and draws it into the page content stream.

A thin horizontal line is then drawn immediately below the text, spanning exactly the width of the name. Nothing else on the page is altered, and the rest of the document is written back unchanged.

Your files are not uploaded. When you add a PDF file, your browser reads it from your device into the memory of the tab you are looking at, and the sign pdf operation runs there using your own processor. Nothing is transmitted to any server at any point.

That means there is no file for anyone to store, no retention policy to trust, and no deletion schedule to take on faith. The document exists only in the memory of an open browser tab, and it is released the moment you close it, reload the page, or press start over.

The site uses standard anonymous analytics to count page views and how often each tool is used. Those events record which tool ran and whether it succeeded — never a file name, never file contents, and never anything that could identify a document or the person processing it.

No account is required, so no personal information is collected. There is no profile, no history and nothing tied to an identity, because no identity was ever created.

The strongest security property this tool has is structural: your file never travels anywhere, so there is no transmission to intercept and no server-side copy to breach. This is not a policy that could change — it is a consequence of where the code runs.

You can verify it in about thirty seconds. Open your browser's developer tools with F12, select the Network tab, and use the tool. You will see the page's scripts load — including the PDF libraries, which are fetched on demand the first time a tool runs — and then nothing further. No request carrying your document is ever made.

For a stronger test, disconnect from the network once the page has loaded. The tool will keep working exactly as before, which is only possible because nothing is being sent.

Uploaded files are validated in the browser before anything runs: the extension must match what the tool accepts, the file must not be empty, and it must be within the size limit. Malformed documents produce a clear error and a retry option rather than a silent failure.

Being clear about limits is more useful than a feature list that quietly omits them. Typed signatures only, one page per run, with no cryptographic signing, certificate, timestamp or audit trail.

If you need capabilities beyond that — redaction, PDF/A conformance, OCR, or scripted batch processing across thousands of documents — dedicated desktop software genuinely earns its licence fee, and this is not trying to replace it. For the specific job of producing a signed PDF, everything you need is on this page.
