How to sign documents on your iPhone

To sign documents on iPhone devices, follow these steps:

1. Download theXodo iOS app on your iPhone from the Apple App Store:

Download iOS App

2. Once installed, tap on the Xodo icon.

3. Locate, select, and open the PDF that needs your signature.

4. Tap on the Lightning Bolt icon from the toolbar and tap on the eSign PDF tool from the list.

5. Then tap on the Create signature button at the bottom. 

6. Add your signature. You can do this in a few ways:

  • Draw: By default, you can start drawing your signature with your finger. Tap on Done in the toolbar. Tap on the page where you want to place it.
  • Type: Tap on the “T” icon to start typing out your signature. Tap on the Done button and then tap on the page to add it onto the page.
  • Upload your signature: Tap on the Image upload icon. Then select the source where your signature image is located. Select the image file of your signature to upload it and tap on the page to place it. Tap Done when you’re finished.

Also, note that when you either type or draw your signature, you can select to save it to Xodo Drive. You can then quickly select it from the signature drop down list the next time you need to sign a PDF. 

Once your signature is placed on the page, you can tap on it and drag on the handles to resize it. To move it, long-tap and drag your signature to where you need it.

7. Tap on Finish. Xodo will process and save the newly signed PDF in your Processed Files list.

To add another signature, ensure that you’ve saved the signature you created. Then while in the same session, ensure that your signature is visible and still active in the signature drop down list. Go to the page where it’s needed and just tap on the area where you need to add it. 

Expert Tip: In cases where initials are required, type or sign your initials instead when you go to create a signature. Save it. When you need to add initials, just select it from the dropdown list and tap where you need it on the page.

How to fill in and sign forms on iPhone?

Need to add your details? Check a box? Filling out PDF forms on an iPhone can sound cumbersome. But the Xodo app lets you easily input your details just as easily as adding your signature. Here’s how to fill in form on iPhone: 

1. Open your PDF in Xodo.

2. Tap on the dropdown list in the upper left-hand corner and tap on Fill and Sign.

3. Tap on the form field functionality you need and then tap on the page where you need it.

4. Fill in your details and information. You can insert a number of details and fields: text and comb fields, date, check boxes, radio buttons, and standard or customized stamps. For text additions, you can customize the text, font, font size, colour, and more.

5. Finally, add your signature to the form by tapping on the Signature Tool icon from the toolbar, selecting or creating your signature and tapping on the page to place it.

When you’re done, Xodo will automatically save the form fields once you tap out of the file. It’ll be saved under your Processed Files folder.

How to review PDF before signing?

We know that official documents needing approval can oftentimes require collaborative review. If you’re looking to quickly include some brief input, use the Annotation features to place them directly on the page.

1. Open your PDF in the Xodo iOS app.

2. Select the Annotate option from the drop-down menu.

3. Tap on the annotation feature you need. Then tap on the page where you have suggestions to make.

4. Add your mark up, text, and annotations as needed. You can add free text, typed text, highlights, notes, strikethroughs, and more.

You can also customize your annotations: select your highlight colour, the font, size and colour of your text, and pen stroke width – just to name a few.

5. Once you’ve added all your annotations, tap on the Lightning Bolt icon and select the eSign PDF tool to sign your PDF using the steps in the first section above.

For reviews that may need more in-depth consideration or comments, you can easily add your annotations and mark ups to PDF pages online, as well.
