Learn all the tricks and best practices of easily editing PDFs on Android.

Editing something you've created is probably just as important as creating it in the first place since things rarely come out perfect the first time around. In fact, we suspect that even Leonardo Da Vinci probably had a draft of the Mona Lisa stashed somewhere safe from prying eyes until he was ready to reveal his masterpiece to the rest of the world.

So, it's safe to say that the idea of refining your creations through editing isn't exactly new and can apply to just about anything – from a pencil sketch in the fourth grade to (you guessed it) editing a PDF file on a phone. But hold on a second...

Can you edit a PDF on Android?

The short answer is yes, you can! Moreover, there are plenty of options for creating a document on your mobile device, whether you need to create a PDF from scratch, convert a PDF from an image or a scanned document, or something else. So, let’s forget the traditional way of handling PDF documents on a PC for a moment and think about how you can easily do this on the go. As it so happens, MobiPDF comes equipped with many tools to help you polish your work or personal projects up to an industry standard.

Now that we learned that editing a PDF on Android is possible...

What are the benefits of mobile PDF editing?

Great question! If you think about it, we already live an "on-the-go" lifestyle: we drink coffee and eat our lunch on the go, so why not also edit PDFs on the go as well? Let's dive into some fundamental details as to why editing PDFs on your mobile device is much more straightforward than it probably sounds.

  • MobiPDF for Android enables you to scan any physical document using nothing but your phone's built-in camera. 

  • With a specialized PDF app, you can do much more than just view files. Whether you've just scanned a document or already have something open on your device, with MobiPDF you will have access to the same deep editing options that you would find on your average PC or laptop.

  • Thanks to modern-day technology, like fingerprint scanners, face recognition software, and built-in password protection systems, your confidential information will always be well-guarded. You could then protect PDFs even further by encrypting them directly within MobiPDF.

  • Sharing your work and files from your phone is much easier than using a PC to do the same job. When editing PDFs on Android, you have all the contacts and address books available at the snap of your fingers. This makes the sharing process effortless and more importantly, much faster.

  • In most cases, editing a PDF on a phone takes up much less time since you can quickly change everything you don't like with a few taps.

  • If you need to convert a PDF on Android, you are most welcome to do so. The PDF conversion process is seamless as you can export PDFs to Word, Excel, PowerPoint, and ePub, just to name a few options. 
     

As we can see from the extensive list above, the mobile screens of today are nowhere near as small and useless as they were back in 2005. You can freely zoom, scroll, and expertly navigate any file, not to mention the rich editing options at your disposal. So, whether you are riding in the back seat of a car, commuting to work, or drinking your morning latte at your local coffee shop, MobiPDF will always have you covered, no questions asked.

How to edit a PDF on Android 

You don't have to be a rocket scientist to edit PDFs on a phone. Let's dive deep into the features you can expect to find once you install the MobiPDF app on your device.

To copy or highlight text, simply exit "Edit" mode and select your text again.

How to add an image to a PDF on Android 

In addition to text editing, MobiPDF for Android offers a variety of other options, such as the ability to add photos, which can help you add more clarity to complex concepts or break up otherwise long-winded walls of text.

Choose where your file is located.

5. Tap on Picture from the bottom menu.

Tap the "Picture" icon in the bottom portion of your screen.

6. Choose between the following options:

  • New picture this option allows you to upload an image from your local or cloud storage.

  • New camera picture  use this to edit PDFs on Android by taking photographs on the go with your device’s camera.

Choose whether to edit a picture, insert a new picture, or use a camera picture.

How to attach a file to a PDF on Android

Since this PDF software allows you to attach files, you might find this option pretty useful as well. The workflow is quite simple:

1. Open MobiPDF.

2. Tap Comment.

As with most annotations in MobiPDF, tap "Comment" to access the file attachment feature.

3. Select which file you need to edit.

4. From the bottom menu, slide left to reveal more options, and tap on Attach file.

Tap "Attach file" to insert any other file format into your PDF, including another PDF.

5. Tap on where you need to insert the file.

How to create a new PDF on Android

Before you start editing PDFs on Android, you should probably explore your options for quickly making one from scratch. Luckily, MobiPDF makes this task a breeze. You can create a new PDF in one of three ways:

1. Go to More → Create Blank. This will allow you to start from a clean slate and build your PDF from the ground up.

Tap "Create Blank" to truly make your PDF your own.

2. From the home menu, tap on Scan to PDF. This will allow you to use your Android phone camera to scan any physical document, which you can then turn into a digital image and insert into a PDF for further changes.

Tap "Scan to PDF" to turn MobiPDF into a portable file scanner.

3. Go to More → Combine PDFs. This will merge two or more documents together into a brand new PDF while preserving the original texts and formatting of each file. 

Tap "Combine PDFs" to merge any number of PDFs into one.
