PDF Signer
About the PDF Signer
The PDF Signer tool lets you draw your signature by hand directly in the browser — using a mouse, trackpad, or touchscreen — and then embed that signature image onto a specific page of a PDF at a position and size you control. This gives you a way to sign a document digitally without printing it, physically signing it, and scanning it back in, which is faster and produces a cleaner, higher-quality result than a scanned paper signature.
The signing canvas responds to both mouse and touch input, so you can draw naturally with a finger on a tablet or phone, or a mouse on a desktop, and there's a "Clear Signature" button if you want to redo your signature before finalizing it. Once you're happy with your drawn signature, you specify the target page, its X and Y position, and a width (the height scales automatically to match your signature's original aspect ratio), and the tool embeds your signature as an image directly onto that page of the PDF.
This is useful for the enormous range of everyday situations that call for a signature on a document — signing a contract, an agreement, a permission slip, an acknowledgment form, or any paperwork where a printed-and-scanned signature would otherwise be your only digital option. Because the signature is drawn fresh each time rather than reused from a saved image file, you have full control over exactly how it looks on each document, and there's no need to store or manage a separate signature image file between uses.
Keep in mind this tool embeds a visual representation of your signature rather than a cryptographically verified digital signature (the kind used in formal e-signature platforms with legal audit trails and identity verification) — for documents where that level of legal signature verification is specifically required, a dedicated e-signature service may be necessary. But for the large majority of everyday signing needs — internal forms, personal paperwork, and informal agreements — this tool provides a fast, private way to add your signature without leaving your browser.
For the cleanest-looking signature, try drawing slowly and deliberately on the canvas rather than quickly, since a steadier hand motion translates to smoother, more natural-looking curves in the final embedded image — this matters more on a trackpad or mouse than it does with a stylus or finger on a touchscreen, which tend to produce more natural strokes by default. If you'll be signing multiple documents in one sitting, you'll need to redraw your signature fresh for each PDF you upload, since the canvas resets between tool sessions rather than remembering your signature between uses — this is intentional, since storing a reusable signature image would mean keeping a sensitive asset around between sessions rather than generating it fresh each time.
Because your signature is drawn fresh each time directly in your browser rather than pulled from a stored image file, there's no signature image sitting on a server or in a cloud account somewhere that could be misused if that storage were ever compromised — the drawing exists only in your browser's memory during the session and is discarded once you close or refresh the page. This makes the tool a reasonably privacy-conscious way to add a personal signature compared to services that store a reusable signature image on your behalf. If you need an official-looking APPROVED or DRAFT marker alongside your signature rather than a hand-drawn one, the Add Stamp tool offers preset stamp labels.
