How to Use Fill to Create an Electronic Signature on an iPad

One advantage of a tablet is the larger display, which makes it easier for you to edit and sign files. Signing documents on an iPad is quite similar to the procedure for iPhones.

Follow the steps below to learn how to sign PDFs on iPad:

Download the Fill app for iPad from the App Store.
Open the app and log in or create a new account. You can use your Google account, Apple ID, or email address.
You can import a new document from iCloud or your device’s local storage to Fill. You could also scan a copy, create a new file, or use a template.
Once you’ve opened the document, tap on the Sign button to create your electronic signature. You can use Fill’s built-in tools to draw, type, or import an existing esignature.
Select and drag your new esignature from the toolbar to your preferred location.
Complete the process by exporting the document to PDF or emailing it to a recipient. You could also use a shareable link to send signed files directly to your contacts.

Fill can become a powerful companion for your mobile workflow. It also saves your esignature so you can sign as many documents as necessary using your smartphone or tablet. The readily available tools can take your productivity to the next level.

Are There Other Ways to Sign PDFs on an iPhone or iPad?

Apart from using Fill, there are other methods you can use to sign documents with your mobile device. You can use Apple’s built-in signing solution or an app from Adobe. Follow the short guides below to learn more.

Sign documents on an iOS device with Adobe Acrobat Reader

Adobe Acrobat Reader is available as an iOS app. You can use it to sign PDFs on your iPhone or iPad. However, it has limited support for other document formats.

1. Download the Adobe Acrobat Reader app for iOS on your device.

2. Sign in using your Adobe ID or register for a new account.

3. Look for the left or bottom navigation pane and select Files. You’ll see the option to upload or import a PDF file from cloud storage or directly from your device.

4. Next, tap the Edit icon and select Fill and Sign. Tap the pen nib button from the menu and select Create Signature or Create Initials. Adobe Acrobat Reader lets you do this in three ways:

Draw your signature in the Sign Here box.
Upload an image of an existing signature
Take a photo of your handwritten signature.

5. Once your signature is ready, tap any document section and wait for the pop-up menu. Then, select the pen nib icon to add the signature.

6. Position and resize the signature however you want. Repeat the process as needed.
Save your changes and export the PDF.

While Adobe Acrobat Reader provides a fast way to sign PDFs, some of its restrictions make it less ideal as an esignature solution. You’ll need to attach the file to an email if you wish to request for other signatures or share a signed document. It also may not have as robust a feature set as other apps.

Use Apple Markup to sign PDFs on an iPhone or iPad

Apple has a proprietary method for signing and annotating documents. With Markup, you can add text, drawings, and images to PDF files. The following steps will help you get started:

Open a PDF file preview on the Mail app. You may also open a document through the Files app.
Once you’ve opened the file or preview, you should see the Markup icon that looks like a pen tip. Tap on it to enter markup mode and start annotating.
Create a new esignature by tapping the plus icon on the bottom and selecting the Signature button. You should then see an option to create an electronic signature.
Next, draw your signature on the given space using your finger or an Apple Pencil if you have one for your iPad. You may repeat the process until you’re satisfied with the signature.
Tap on Done and select your esignature. You may enlarge, shrink, and drag your signature anywhere inside the document.

It’s possible to create multiple esignatures on your Apple device. They will appear as an option inside the Markup interface the next time you need to use them.
