How to digitally sign a PDF with your mobile

Reduce PDF size

Regardless of who it weighs, technology does not stop advancing and every day it is being adopted by a greater number of people, companies and public administrations. To this we have to add that practically no one has a printer at home to print documents and sign them.

In this article we are going to offer you the solution to the technological changes that surround us, showing you the steps to follow to sign a PDF with your mobile, without having to print the document in no time, which allows us to perform this task from anywhere.

Adobe (creator of Photoshop) created the PDF format in the late 90s, but it didn't catch on until the early 2000s. That's when it became a standard within the industry.

When a format becomes standard, all operating systems automatically add support, that is, it allows us to open these documents without having to install a third-party app.

The format PDF y ZIP These are two clear examples of the standardization of formats. However, if we want to sign a PDF document, we cannot do it natively on mobile, not natively on Windows, but on macOS and iOS.

In this article we are going to focus on showing you the best applications available in the Play Store for sign PDF documents on mobile.

How to sign a PDF on mobile

If we talk about applications to sign PDF documents, we have to talk about the Adobe Acrobat Reader application for PDF, an application that we can download directly Totally free from the Play Store.

Being Adobe the creator of this format, there could not be a better application for this task. Despite being an application designed to read documents in PDF format, it also allows us to make notes and sign any document in this format, without having to use any of the different applications available in the Play Store.

Once we have downloaded the application, when opening the application for the first time, will invite us to register, a process that we can do with our Google, Facebook or Apple account.

Really registering is absolutely useless, but it is the only way to access the application. If you already have an Adobe account, you can use it without creating a new one.

Once we have installed the application and we have registered, we access where the document is that we have to sign. When asked which application we want to open the document with, we select Adobe Acrobat.

If we are not clear enough, we can use the Adobe Acrobat application, through the Files tab to find the document. From Adobe Acrobat, we can open pdf files that is found:

  • Stored on the device or in the Adobe cloud
  • On Google Drive, OneDrive or Dropox
  • Or in a Gmail email where the document we want to sign is located.

Once we have opened the PDF document that we want to sign, click on the pencil that is shown in the lower right corner and select Fill and sign.

Next, at the bottom of the application, click on the pen, located in the lower right corner of the application.

In the drop-down menu that is displayed, we find two options:

  • Create signature
  • Create initials

These options will appear the first time we use the application. If we are going to use it more than once, we must know that the application will store the signature and it will be available to us for future uses.

  • Use a scanned image of our signature that we have stored on our device

Once we have added the signature in the correct position, click on the V located in the upper left corner on the screen to confirm changes to the document. The next step is to share the document with the person who sent it to us.

Send signed PDF document

To share the document we just signed, we have two forms:

  • Share the document from the Adobe cloud, who will take care of sending a link to the recipient (not recommended)
  • send it through a mail application, messaging...

By selecting this last option, all the applications that we have installed on our device and with which we can send the PDF document that we just signed.

In addition, we can take advantage of store it in our Google Drive account or any other cloud storage platform that we usually use using the same method.
