How to sign a PDF
- Open your PDF. Go to Lilli PDF and choose your file, or drag it onto the page. The file is opened on your own device.
- Choose Sign and draw your signature. Draw with your finger on a phone or tablet, or with your mouse on a computer. Pick black or blue ink. Not happy? Clear it and try again.
- Place it and save. Choose Place, then drag your signature to the right spot and make it bigger or smaller. Choose Save to download your signed PDF as a new file.
Sign on your phone, just like on paper
A signature drawn with your finger looks much more natural than one made with a mouse. Lilli PDF is made for touchscreens, so you can sign a form, contract or letter straight from your phone or tablet.
Want to use the same signature again? Tick “Keep on this device”. Your signature is then stored in your own browser, only for you, so next time you can place it with one tap.

Good to know
- Lilli PDF places your signature as a picture in the PDF. This is a simple electronic signature, like signing on paper and scanning it.
- It is not a digital signature with a certificate. Some official documents require one; check with the organisation that asks for your signature if you are not sure.
- You can keep up to four signatures on your device. They are stored in your browser only, so clearing your browser data removes them.
