Someone may send you a PDF file via the email and require you to sign it before sending it back. While you could always print the document, sign it in hardcopy, and then scan it, this is time-consuming and will use a lot of resources. A better alternative would be to electronically sign a PDF. In this article, you will learn how to esign a PDF.
Is There Any Difference Between Digital and Electronic Signatures?
In this article, we will focus on electronic signatures, not on digital signatures. Compared to the electronic signatures, the digital signature is entirely different.
Digital signatures are cryptographically secure – they verify that someone who has your private signing key (this should be you) has already seen the document and authorized it. Being secure, digital signatures are more complicated.
The electronic signature is just an image of the signature that you overlay over the PDF document. Adding an electronic signature to a PDF file is generally much easier – you can use a wide range of applications.
How to Esign a PDF? 5 Methods Here!
1. Use Adobe Reader
Adobe Reader features a large number of tools that you may want to use when you are viewing your PDF files. While it is not the most lightweight Portable Document Format (PDF) viewer, it features excellent support for PDF document signing.
While other third-party tools may offer you the ability to sign your documents, the tools will probably force you to invest in a paid version so that you can have the ability to sign your document. With adobe reader, you should be able to sign your PDF for free. Below, we have the steps you will need to follow:
Step 1: Open the file in the Adobe Acrobat Reader DC application.
Step 2: On the right pane, hit the Fill & Sign option.
Step 3: On the toolbar, hit the Sign button and then choose Add Signature.
You will be able to add your signature via 3 main ways. By default, Adobe Reader will choose the Type option. This allows you to type your name and then convert it into a signature. This will not appear to be your real signature in most instances. For this reason, you may want to opt for the Draw option. After selecting the Draw option, you can then go ahead and draw your signature using either a touchscreen or a mouse.
If you would like to sign a paper, scan it and then insert a signature into a PDF, you will need to choose the Image option. While this option does require scanning, the scanning will only be necessary once. After that, you can use the scanned signature on all the other PDF documents which will need signing in the future.
Step 4: After creating the signature, hit the Apply button. This will apply the signature to the document.
Note: To quickly add the signature to future documents, put a checkmark on Save Signature.
Step 5: Position the signature where you would want it to appear.
Step 6: To save the signed PDF file, hit the File option on the top-left corner, select Save, and then choose a location on your hard disk where you would like to save the document.
Note: You can use Adobe Reader on both Mac and Windows PC.
2. Use Preview to Insert a Signature Into a PDF
On Windows, it is impossible to esign a PDF using the default applications. You will have to install an application such as the Adobe Reader described above.
Mac users are basically luckier, compared to the Windows users – they can use the Preview feature to sign their PDF documents. Thanks to the effective trackpads available on the MacBooks, you should be able to draw the signature on the trackpad. If you already have the Force Touch trackpad, this may allow you to draw more accurate signatures – the Force Touch trackpad is more pressure-sensitive.
If drawing the signature directly appears too tough, you can always draw the signature on a piece of paper and then scan it using the webcam – this is an effective option if you are using a Mac computer that does not have a trackpad.
To learn how to esign a PDF on Mac using the Preview option, you will need to follow the simple steps we have outlined below:
Step 1: On your Mac, launch your PDF file in the Preview. If this is still the default application you use to view your PDF files, all you will need to do is double-click the document. If you have changed the default PDF viewer, you may need to right-click your document and then choose open with Preview.
Step 2: Hit the Show Markup Toolbar button – this should look like a toolbox.
Step 3: Next, hit the sign button on the toolbar that appears.
Step 4: Your Mac will prompt you to either track your finger on the trackpad to create a signature or sign on a paper and then scan the signature using the webcam. After capturing the signature, the Preview feature will remember it in the future.
Step 5: Select the signature from the menu that shows after you hit the Sign button. The signature will be applied as an image. You can drag it around and even resize it to fit the document ideally.
Step 6: After you are done with signing the PDF file, hit the File option and then select the Save option to save the signed document. Alternatively, to create a duplicate of the PDF document and save the changes into a new file, you will need to select File > Duplicate. If you use the Duplicate option, the new copy will be modified, instead of the original one.
3. How to Esign a PDF on iPad and iPhone?
Use the Mail Option
On your iPhone and iPad, you can easily sign your documents using the Markup feature available in the iOS mail application. If you own a Mac and you have used the Preview option to sign documents in the past, the signature may actually synchronize from the Mac to the iPad or iPhone – this will eliminate the need to create the signature again.
This feature is quite convenient. However, it will only work if your goal is to sign the documents in the Mail application. To give you an example, you could have been emailed the PDF document and you may want to sign it and then email it back immediately.
To electronically sign a PDF using the Mail application on iPad and iPhone, you will need to follow the steps outlined below:
Step 1: After receiving a PDF attachment via the Mail application, hit the Markup and Reply icon (this should be shaped like a toolbox). The icon will be available on the bottom-right corner of the screen when you are viewing the PDF file.
Step 2: Tap the signature button to add your signature. If you like, you can also draw on the document or type text.
Step 3: When you are done with adding the signature, hit the Done button. The mail application will create a reply to the email with the signed document already attached. You can then go ahead and type your message before sending the PDF file back.
Use the Adobe Fill & Sign Application
The Mail app is quite limiting – you can only use it with email documents. If you would like more flexibility when it comes to signing documents on your iPhone or iPad, you will need to use Adobe Fill & Sign application. The application is 100% free and you can get it on the App Store.
You can sign a document by drawing on your screen using a stylus or your finger. You can also type into a PDF document to fill it. Below, we will show you the steps you will need to follow to insert a signature into a PDF using the Adobe Fill & Sign application:
Step 1: To get a PDF file from a different app (say an Adobe Reader) into Adobe Fill & Sign, locate the file and then hit the Share button. From the dialogue that appears, select Adobe Fill & Sign application.
Step 2: To sign the document, choose the signature button.
Step 3: Once you are done, hit the Share button within the Adobe fill & Sign application to send the already signed document to a different application.
Note: Adobe Fill & Sign application is also available on Google Play Store. If you would like to sign documents on a device running on Android, you can download the app and install it on your Android phone or tablet. To sign a PDF on your Android device, you will need to follow steps similar to the ones we have outlined above.

Step 5: Tap on the ballpoint pen icon and then choose the ideal font color and the size for the signature.
