By MyDigitSign Editorial•July 10, 2026

If you're out of the office and need to sign an urgent contract, agreement, or lease, you don't need a computer. You can easily complete an e signature pdf online or offline using your mobile device. In this guide, we show you how to sign document for free on any iOS or Android phone or tablet.

How to Sign a PDF on iPhone & iPad (Using Markup)

iOS devices come with a built-in feature called Markup, which allows you to draw or insert your handwritten signature onto files stored in the Files app or received in Mail:

Open the PDF in the Files or Mail app.
Tap the Markup icon (the pen-in-circle emblem) in the top-right corner.
Tap the + button in the bottom menu and select Add Signature.
Draw your signature with your finger or use a previously saved one.
Drag it onto the signature line, scale the box, and tap **Done** to save.

Upload the File: Tap the uploader to browse your device files and select the PDF or image document.
Place and Resize: Drag the signature overlay to the correct field, and scale it.
Download: Click Download to save the signed PDF directly to your device storage. Since it runs client-side, your document is kept completely secure and private.

Is it Free and Secure to Sign on Mobile?
