How to sign a PDF on iPhone
You don't need an app to sign a PDF on your iPhone. Open the signing link in Safari, draw your signature with your finger, and you're done. Here's how.
Open the signing link
When someone sends you a document through SignOwl, you receive an email with a 'Sign Document' button. Tap it — it opens directly in Safari. No app store, no downloads.
Review and sign
Pinch to zoom on the document. When you reach a signature field, tap it. A drawing pad appears — sign with your finger. Tip: rotate to landscape mode for a wider signing area.
Sending documents from iPhone
To send a document for others to sign, open signowl.app in Safari, sign in, and upload your PDF. The full sender experience works on mobile — place fields, add signers, and send.
