Sign PDF

Sign a PDF without printing, signing, and scanning it like it is 2009. Draw your signature with a mouse, trackpad or finger, drop it exactly where you want it, any page, five positions, three sizes, and download the signed file. It all happens in your browser, so the document never leaves your device. One honest note: this adds a drawn electronic signature image, not a certified cryptographic digital signature.

Draw your signature

Draw with your mouse, trackpad or finger. This adds a drawn electronic signature image, legal validity varies by document type and jurisdiction.

The formula

Your PDF is loaded in memory and its page count is read, so you can pick the exact page to sign.
You draw your signature on the pad with your mouse, trackpad or finger; the strokes are captured as a high-resolution transparent image.
The signature image is embedded into the chosen page at your selected position and size, with a clean margin from the page edges.
The document is re-saved locally and offered as signed.pdf, the original file is never modified and nothing is uploaded anywhere.

A worked example

A one page rental agreement: open it, draw your signature on the pad, keep page 1 with the Bottom right position, press Sign PDF, and download signed.pdf ready to email back.

More about the Sign PDF

Drawn signatures: when they work

The everyday scenario: your landlord emails a one page rental agreement. Open it here, draw your signature on the pad (redo it twice until it looks like you), keep page 1 and the bottom right position, press Sign PDF, download signed.pdf, and email it back. Elapsed time: under two minutes. The print sign scan dance it replaces took twenty.

This is the right tool for the mountain of low stakes paperwork modern life produces: school permission slips, HR onboarding forms, freelance statements of work, delivery confirmations, tenancy renewals. Anywhere a human needs to see that you agreed, a drawn signature does the job. It is the wrong tool for the small set of documents where the law wants cryptographic proof of identity and tamper evidence, property deeds, notarised documents, court filings. Knowing which pile your document is in is the whole game.

Legal weight and a signing workflow that holds up

Practical tips. Draw bigger than you think on the pad, a large, confident stroke scales down better than a timid small one. On a desktop, a trackpad beats a mouse for signature like curves; on a phone, use your fingertip and rest your wrist. Place the signature, then zoom the preview and check it sits on the line, not across the text. And sign a copy, not your only original, so you can redo it if the placement is off.

And stated plainly, the limits: drawn signature images only, no typed text, no uploaded image, no cryptographic certificate, one signature placement per run, and encrypted PDFs are refused. The signed file is a normal PDF anyone can open; the signature proves nothing cryptographically, which is fine for everyday agreements and insufficient for regulated ones. It is unlimited, free, and your document never leaves your device.

Signing on mobile: the iPhone and Android workflow

The whole flow works in the mobile browser. Open the PDF in Safari or Chrome, tap to add text where the form asks for it, then create your signature, draw it with a finger for a natural look or type it in a script style for neatness.

Place the signature, resize it to fit the line, and download. The signed PDF is a normal file you can email or upload anywhere, no proprietary format, no viewer required on the other end.

Frequently asked questions

Is a drawn signature legally binding?

It depends on the document and where you are. Drawn electronic signatures are accepted for a huge range of everyday agreements, rental forms, HR paperwork, school forms, freelance contracts. But regulated documents (property transfers, court filings, some financial contracts) may require a certified cryptographic signature instead. When the stakes are high, check your local rules before signing.

I messed up my signature. Can I redo it?

As many times as you like. Hit Clear signature on the pad and draw again, nothing is final until you press Sign PDF and download. Take your time; a signature you are happy with matters.

Exactly where can I place the signature?

Any page number you choose, in one of five spots: the four corners or bottom centre. Sizes come in small, medium and large. Bottom right at medium size is where signatures conventionally live on agreements, which is why it is the natural default.

Can I type my name or upload a signature image instead of drawing?

No, this tool is draw only. That is a deliberate simplicity choice: the pad works with mouse, trackpad or finger on any device, with nothing to upload or format. If you need a typed or image signature, most PDF desktop apps offer that.

Can I sign on my phone?

Yes, and it is arguably the best way: drawing with a finger on a phone screen feels more natural than a mouse. Open the page on your phone, pick the PDF, draw, place, download, then email it straight back. Rotate your phone sideways if the signature line is long, the wider pad gives your finger more room and the result looks noticeably steadier.

What about password protected PDFs?

The tool cannot open encrypted PDFs and will tell you so. Remove the password first with the owner password, then sign. And remember the honest framing: this places a signature image; it does not certify or lock the document the way a cryptographic signature does.

Can I save my signature to reuse on the next document?

The Sign PDF tool keeps your drawing on the page while you work on the current document, so you can stamp it wherever it is needed without redrawing it. For future documents, most people keep a small image file of their signature handy. You can upload it through the same tool in seconds. That keeps your signing routine consistent across contracts, forms, and offer letters.

Can two people sign the same PDF, or just me?

Signing in turns works well: the first person signs the PDF, downloads the signed copy, and sends it to the next signer, who opens it in the Sign PDF tool and adds their own signature. Each signature is placed separately, so you can see exactly who signed where. It is a simple way to handle landlord tenant forms or agreements that need more than one hand.

Is a typed signature legally valid?

In most cases, yes. The US ESIGN Act and the EU eIDAS regulation both give electronic signatures, including typed names, legal standing, provided there is intent to sign and a record of the process. Some documents (wills, certain court filings) still need wet ink or qualified signatures, so check your jurisdiction for high stakes paperwork.

What is the difference between an electronic and a digital signature?

An electronic signature is any mark of intent, a typed name, a drawn squiggle, a clicked I agree. A digital signature is a specific cryptographic technology proving who signed and that the document was not altered after. For everyday contracts electronic is enough; regulated filings may require digital.
