3 Simple Methods | How to Sign PDF on Android

Crystal Chen updated on Aug 30, 2023 | Home > PDF Knowledge Center | min read

Physical copy documents are giving way to soft copies as they are easier to store and share. Plus, they take up much less space. So, having to sign documents in PDF is becoming the new normal. Some years ago, it involved a tedious process. You had to download the document, print it, and sign it.

Thankfully, it is now much easier to do now. That said, if you have to sign PDF on Android, you still have it more challenging than people sign PDF on iPhone devices with their convenient in-built feature. Luckily, with the help of a document signing app, you can still sign on digital copy documents and share them right from your Android phone.

In this article, we will discuss a few tools for this and the steps you should take. Let's get right to it.

Method 1. Sign PDF on Android with Adobe

The Acrobat Reader app is a standalone mobile app that allows you to open and read PDF files. It is a product of Adobe, one of the leading names in digital media and digital marketing software solutions.

Acrobat Reader is a streamlined version of Adobe Reader DC. On its free version, you can search, annotate, fill, print, and send PDF files. More relevantly, you can sign a PDF without printing on your Android phone with it. Upgrading to the premium version unlocks extra abilities.



Here's how to sign PDF on Android with the Adobe Acrobat Reader:

Step 1. Download Adobe Acrobat Reader from the Play Store and install it on your Android phone. 

A sign-in prompt will pop up as soon as you launch the app. Create an account or sign in to continue.

Step 2. Tap "Files" on the footer of the screen.

Step 3. Select the source and locate your PDF document. When the document displays on the screen, tap the "Edit" icon near the bottom-right corner.

Step 4. From the menu, tap "Fill & Sign".

Step 5. Draw your signature in the field provided with your finger or stylus. Click "Done" to save.

Step 6. Tap on the appropriate area to place the signature. 

You can adjust its size to your preference or tap the "Trash" icon to delete it.

Method 2. Sign PDF on Android by Using iLovePDF

iLovePDF is another document management tool for Android. It can let you view, convert, search, annotate, and sign PDF online, so you do your work on the go. iLovePDF is packed full of features, with many available upon an upgrade to a premium account.



Here's how to sign PDF on Android with the iLovePDF:

Step 1. Open the document you need to sign from one of the storage categories.

Step 2. Tap the "Menu" button in the top-right corner and select "Tools".

Step 3. Scroll down the list of options to "Sign PDF" and tap it.

Step 4. The signature icon will display at the bottom-right corner. Tap it.

Step 5. Draw your signature in the field provided with your finger or stylus. Tap the "check" button to save it.

If you want to redraw the signature, tap the "Trash" icon instead.

Step 6. Drag the signature to the appropriate area in your document. Tap any empty space to confirm the position and click the "check" button to save.

Method 3. Sign PDF on Android in SignEasy

This is one of the most lightweight options for signing PDFs on Android. That is because, unlike the others that come with several features, Standeasy is a standalone eSignature app. It works with various file formats, including PDF, Word, Excel, PNG, and JPG. SignEasy's free trial is limited, restricting you to three uses.



  • Sign documents
  • Save frequently used documents as templates
  • Fingerprint authentication
  • Customize signatures

Here's how to sign PDF on Android with SignEasy:

Step 1. Download SignEasy from the Play Store and install it. Sign in or create an account to continue.

Step 2. Tap the "plus" icon near the bottom-right corner to import a document.

Step 3. Select a source from the options.

You can fetch a PDF from your device, email, or the cloud.

Step 4. Tap "Start Signing".

Step 5. The signing options will display. If you are the only signer, tap "Sign Document". 

Step 6. Select "Signature" from the annotation menu.

Step 7. Draw your signature in the field provided with your finger or stylus. Tap the "check" button to save it.

Step 8. Drag the signature to the appropriate area in your document. Tap any empty space to confirm the position and click the "check" button to save.

Bonus Tip: How to Sign PDF on Windows

The entries discussed above will let you sign PDF on Android devices. That works, but it is not the preferred choice for all users for a few reasons.

For one, apps that let you sign PDFs on mobile are usually stripped-down versions of computer apps. Because of this, they may lack some features available on the full apps. What's more, handling documents on smaller phone screens can be a tedious affair. So, you may prefer to sign your documents on a computer instead.

EaseUS PDF Editor is the recommended choice if you use a Windows system. The all-in-one software offers features to create, read, edit, converti, sign, or lock a PDF. The tool sports a clean, elegant interface that is free of clutter. It is also easy to use and intuitive, so beginners don't face a steep learning curve. Now click here and download it!


Here are the steps to sign a PDF with EaseUS PDF Editor:

Step 1. Launch EaseUS PDF Editor and click "Tools". Then, choose "Signature". Import your PDF file form your computer. If the file is locked, you need to enter the password to unlock it first.

Choose Signature

Step 2. In the next window, you will see a tool bar containing "Digital signatures", "Handwriting signature", "Manage signatures", etc. Choose the one you need.

Signing Tools

Step 3. After editing, you can click "File" > "Save as" to save the PDF file to your computer.
