A signature should not require an account.

Falcon Sign is a PDF signature tool that lets you draw a visual signature and stamp it onto a chosen page, position, and size. The drawing pad and the file both live in this browser tab; cryptographic signing lives in Falcon Verified.

The drawing pad lives in this tab. The PDF lives in this tab. The signed file lives in your downloads. By design.

Why this tool exists

Every major e-signature service is built around the idea that your signature lives on their server. You sign once, somewhere, and the trace of your signature — the strokes, the timing, the IP, the device — joins a long index of things they know about how you sign your name. The signed PDF arrives a day later, with a cover sheet announcing where the signature actually was.

A visual signature drawn on your computer skips the index. The pad is in this tab. The strokes are yours. The PDF is yours. The version that lands in your downloads is the same one you would have produced with a pen on paper, except that nobody collected a copy along the way.

FAQ

Common questions

Does my document get uploaded when I sign it?

No. The PDF opens in this browser tab and the signature is placed on the page on your computer. Contracts and letters often carry sensitive terms — keeping the signing local means the document is never sent anywhere to be signed.

What kind of signature can I add?

You can draw a signature, type one, or place a signature image, then position it where it belongs on the page. The mark is added to the document as you export it.

Is this a legally binding electronic signature?

It places a visible signature on the page, which is what most everyday agreements ask for. It is not a certificate-based qualified electronic signature; where a jurisdiction or counterparty requires that specific standard, use a provider that issues signing certificates.

Can I sign anywhere on the document?

Yes. Place the signature on any page and position it precisely — over a signature line, beside a date, wherever the document needs it. The placement happens in your browser before the file is written.

Does signing change the rest of the document?

No. The signature is added on top; the existing pages, text, and layout are left intact. You get the same document with your signature in place.

How your file stays private

No upload

Opens, parses, rewrites on your device. Nothing about the contents transits a Falcon server.

Zero logs

No filenames, sizes, contents, or per-file telemetry. Operation counts only.

No trackers

Open the Network tab during use. Only first-party JS appears in the request log.

Metadata stripped

Authors, edit history, EXIF, and embedded thumbnails are removed alongside the visible content.

Smaller file, same place. Pages are re-rasterised at a chosen JPEG quality — heavy decks shrink without ever leaving the tab.

Falcon Crop

pdf.falcon.enterprises/crop

Trim the page, not the trust. Drag a rectangle on the preview and the same frame applies to every page in scope.

Falcon Compare

pdf.falcon.enterprises/compare

See what changed without sending either version away. The diff is a single PDF with red outlines on every changed region.

Falcon PDF/A

pdf.falcon.enterprises/pdf-a

Archival should not require an archive elsewhere. Pages flatten to images, scripts and fonts drop, and the file is sealed for the long term — here.
