Edit documents before sending for signature

Before requesting an electronic signature, you may need to make quick edits to your PDF document. The Xodo iOS app includes a flexible PDF editor to help you prepare documents efficiently.  

Add text or annotations

Use the View & Edit tool to fill in missing details like names, dates, or addresses. You can also highlight or markup key sections for clarity. Read how to edit PDFs on iPhone for step-by-step instructions.

Rearrange or delete pages

A few taps let you reorder the pages, remove blank ones, or adjust the layout if additional references are required.

Fill forms and add signatures

Use Xodo’s standard PDF tools to fill out forms and add basic e-signatures. These are ideal for internal use or informal approvals, but they aren’t legally binding and don’t include tracking or verification.

Redact sensitive data

Use the premium Redact PDF tool to permanently remove confidential data before sharing or sending the document for signature.

Xodo Mobile helps you avoid delays caused by incomplete or incorrect documents. You can make quick fixes, clarify terms, and send a polished file, all from your phone.

Note: Xodo Sign and Xodo mobile app are part of separate subscriptions. Xodo Sign features require a free Xodo Sign account, while mobile PDF editing and viewing tools are available under a different in-app subscription.
