How to sign a PDF on your phone

What you need

• The PDF to sign, saved on your phone (from an email, a messaging app or your files).
• A web browser: Safari, Chrome, Firefox or Samsung Internet.
• That’s it: no account to create and no app to install.

Sign the PDF step by step

1. Open the “Sign PDF” tool in your phone’s browser and select the document.
2. Under “Your signature”, draw your signature with your finger. You can also type your name and pick a handwriting style.
3. Choose black or blue ink.
4. Drag the signature where you want it on the page, and pull its corner to resize it.
5. Choose which pages to sign (the current page, the last page or all pages), then tap “Sign PDF”.
6. Download the signed document and send it back by email or messaging app.

Tips for a good signature

• Turn your phone sideways to have more room to sign.
• Use a stylus if you have one: the stroke will look more natural.
• To reproduce your real signature, sign on a blank sheet of paper, take a photo of it and choose “Image”: PDFRoll can remove the white background.
• Check the option that adds today’s date under the signature if the document asks for it.

Fill in the document before signing

If the PDF has fields to fill in (name, address, checkboxes), use the “Fill in a PDF form” tool first. If it has no fields, the “Edit PDF text” tool lets you add text anywhere on the page. Then sign the completed document.

Is this signature valid?

It’s a visual signature, equivalent to a scanned handwritten signature. It’s accepted for many everyday documents: quotes, purchase orders, parental consent forms, leases, depending on what the recipient accepts. Some documents, however, require a certified electronic signature linked to your identity. If in doubt, ask the recipient.
