How To Add Digital Signature To Pdf On Iphone

With Markup, you can digitally sign PDF documents on your iPhone, iPad or iPod touch.

You can add your signature to a PDF file or manually sign a document pretty much anywhere Markup tools are available, including Apple's first-party apps such as Mail, Photos, Safari, Notes, Files and others. Apple's made available similar Markup features in macOS as well so you can feel free to sign a PDF document in Preview using your Mac's trackpad.

Signing documents digitally is a great productivity feature.

Say you're out and about with your iPhone or iPad and someone happens to email you a contract, a lease agreement, an Internet service form or another important document that needs signing quickly. With Markup, you don't need to print out the document, sign it the old-fashioned way with a pencil, then scan the printout to send it back as an attachment.

Before we dive into the tutorial, know that Markup features require iOS 9.0 or later.

How to sign PDF documents on iPhone and iPad

You can add a previously saved signature or manually sign a document.

5) Feel free to drag your inserted signature to move it around freely or resize your digital signature by using the blue buttons to grow or shrink the surrounding box.

TIP: To change the ink color, tap the digital signature you just applied to a PDF document and select any of the color circles provided at the bottom of the Markup interface.

6) Tap Done to save the changes.

TIP: Invoke Markup faster on iPad by placing your Apple Pencil on what you'd like to annotate.

Saving and managing your signatures

You can add one or more signatures to re-use over and over again.

1) Open a document from the Files app.

2) Tap the Markup icon at the top.

3) Tap "+" at the bottom of the Markup interface.

4) Choose Add or Remove Signature from the popup menu.

Remove a signature: Tap "-" next to a previously saved signature, then choose Delete.
Add a signature: Tap "+", sign your name on the line and hitDone.

Unsatisfied with the way your digital signature has turned out? HitClear to start over! When you're finished, tap Done to save your newly created signature and insert it into your document.

You can have as many saved signatures as you'd like.

As I mentioned earlier, the signature feature is available anywhere Markup is accessible.

For instance, you can easily add your signature to any image in the Photos app. Or, you could sign a PDF kept in a third-party cloud storage service, right from the Files app. Perhaps you'd like to quickly send a signed PDF attachment to someone without leaving Mail?

With Markup, you can do all that and then some more!

TIP: How to create a handwritten email signature on iPhone

On iPad Pros and 2018 or newer iPad models, use Apple Pencil to scrawl your signature.

Your saved signatures are kept in sync across your iPhone, iPad, iPod touch and Mac devices as long as they're signed in to the same iCloud account. Plus, any signatures already created in Preview for Mac will automatically appear in iOS's signature inserter, and vice versa.

If you use Notes as your document scanner, you can sign any scanned document and send it quickly via mail, iMessage or another service without ever leaving the Notes app.

TIP: Annotating Messages attachments

Similarly, you can use the Markup tools to sign an agreement that was attached to an email message and send it back on its way without switching apps—Mail intuitively inserts your newly signed attachment into a reply to the original email it came in.

And with Instant Markup, you can annotate screenshots right after taking them.
