How to sign a PDF
Open the PDF
Click Sign a PDF and choose the file. Bullet PDF opens it in Fill & Sign mode.
Create your signature
Choose Signature in the tool strip. Draw it (pressure-sensitive on a pen or touch screen), type your name and pick a handwriting style, or upload an image — the white background is removed automatically.
Place, date and download
Click where the signature goes, resize it if you like, add Date and Initials where they are needed, then press Download PDF.
Everything a signing session needs
Draw, type or upload
Three ways to make a signature. Drawn signatures use pressure and speed for a natural pen line.
Initials and dates
Save initials alongside your signature, and stamp today's date in the format you prefer.
Saved on this device
Your signatures are kept in this browser's storage so the next document takes seconds. Delete them any time from the Signatures manager.
Fill in the form too
Text fields, checkboxes, radio buttons and dropdowns in the same mode, so a contract or application is done in one pass.
Signature fields
PDFs with a signature field show a Sign here prompt; click it and your signature is fitted into the box.
Flatten on download
Choose Download flattened PDF to bake the form and signatures into the page so they cannot be edited afterwards.
Questions about this tool
Is a signature made with Bullet PDF legally binding?
Bullet PDF places a picture of your signature on the page — an electronic signature, like signing on paper and scanning it. In many places, including Australia, the UK, the EU and the US, this kind of electronic signature is accepted for most everyday agreements. It is not a certificate-based digital signature: there is no cryptographic certificate or identity check. Some documents (deeds, wills, some government forms) need a specific signature type or a witness, so check what the recipient requires.
Can I sign with my finger on a phone?
Yes. The drawing pad works with touch, a stylus or a mouse, and it is pressure-sensitive on devices that report it.
Can I upload a picture of my real signature?
Yes. Upload a photo or scan; Bullet PDF removes the near-white background and crops to the ink, so it sits cleanly on the page.
Is the signed PDF sent anywhere?
No. The PDF is opened, signed and saved entirely within your browser. There is no server, no account and no email step — you download the file and send it however you like.
Can someone remove my signature from the PDF afterwards?
Like any PDF editor, someone with the file could edit it. Download the flattened PDF so the signature becomes part of the page, and keep your own copy.
Can I sign several PDFs in a row?
Yes. Your signature stays saved on this device, so open the next document, choose Signature and place it. Nothing needs to be redrawn.
Ready?
It opens in a second. Nothing to install, nothing to sign up for.
