How to sign a PDF in your browser
- Drop your PDF onto the box above, or click it to browse. One document at a time, and the file stays on your own device.
- Draw your signature in the dashed box with a mouse, a trackpad, or your finger on a phone or tablet. The Clear button wipes the box if the first attempt comes out shaky.
- Choose the page from the drop-down. The last page is selected for you, because that is where most signature lines sit.
- Click the exact spot on the page preview where the signature belongs. A dashed marker shows how it will look, and the width slider — 80 to 300 points, 150 by default — scales it up or down.
- Press “Sign PDF”. The signed copy downloads with -signed added to the original filename.
What people use it for
Most day-to-day paperwork simply needs a visible signature in the right place, returned as a tidy PDF rather than a photograph of a printout. That is the job this tool does, without involving a printer or a scanner.
- Signing a delivery note or a goods-received form on a phone, standing next to the pallet.
- Returning a rental agreement, a school consent form or a holiday request to whoever sent it.
- Adding a signature to a quotation or an invoice before emailing it back to a client.
- Countersigning an internal form when the office scanner is two floors away.
- Putting an initial in the corner of a document you have been asked to review.
Good to know
This places a picture of your handwritten signature onto the page. It is not a cryptographic or digital signature: there is no certificate behind it, no identity check and no tamper-evident seal, so a PDF reader will not show a green “signature valid” badge. If you are dealing with something that explicitly demands a qualified electronic signature, you need a certificate provider instead. For everything else — delivery notes, internal forms, rental paperwork, routine approvals — a drawn signature is exactly what is being asked for, and it is the same thing you would produce by printing, signing and scanning, only faster and legible.
The document is opened, drawn on and rebuilt entirely by your own browser. Nothing is sent anywhere, which matters here more than on most tools: a signed contract is the last file you would want sitting in a stranger's upload folder. The signature drawing is not stored either — reload the page and the box is empty again. Page rotation is taken into account, so a sideways-scanned or landscape page gets the signature the right way up. If the finished document also needs locking, Protect PDF adds a password, and Merge PDF will join the signed page back onto a longer bundle.
Questions people ask
Is a drawn signature legally binding?
In many everyday situations a signature you draw yourself is treated much like ink on a scanned page. Whether that is sufficient depends on your country and on the kind of agreement, so for anything high-value or regulated, check what form of signature the other party actually requires before relying on this.
Can I sign more than one page?
Run the tool again on the file you have just downloaded and choose a different page. The signature has to be redrawn each time, so it will not be pixel-identical — though neither are two signatures made with a pen.
Why does my signature look thin on the finished PDF?
The drawing is cropped down to the strokes you actually made, then scaled to the width you picked, so a small, tight scribble ends up short and wide. Draw larger in the box, or raise the width slider before placing it.
What if the document is password protected?
Remove the password first with Unlock PDF, using the password you were given, then sign the unlocked copy.
