How to Edit Existing PDF Files in Linux Using Master PDF Editor

Portable Document Format (PDF) is one of the most commonly used formats for exchanging documents, especially on the Web. While its USP is that it maintains the consistency of a document, the uneditable nature of PDF documents is a disadvantage when compared to other easily-editable file formats like DOC and TXT.

In this article we will discuss how we can create as well as easily edit existing PDF documents on Linux using Master PDF editor. Please note that all instructions as well as examples used in this article are tested on Ubuntu 14.04.

Depending on the Linux distribution you are using, you can download the editor’s installation file from its official website (it’s worth mentioning that the tool is also available for Windows and Mac, yet the Linux-based version is free for non-commercial use).

For example, in my case I downloaded the .deb file and installed it using the Ubuntu Software Centre that comes pre-installed with Ubuntu. Once done, you can open the Master PDF editor from Dash (see below).

Open the Master PDF editor from Dash.

In this section, we will discuss a few examples of how to create as well as edit PDF files using the Master PDF Editor tool.

Create a new PDF file

Once you’ve opened the editor, go to “File -> New” to create a new PDF file:

Go to File->New to create a new PDF file.

This will create an empty PDF file.

Note: While you can easily create PDFs using Master PDF Editor, it’s worth mentioning that the tool, as its name suggests, is primarily aimed at editing PDF files. This means you can continue creating PDFs using other well-known software that you are used to (e.g. Libreoffice Writer), and edit them using Master PDF Editor.

Add text

To add text to a PDF file, first open it in the Master PDF Editor. In my case, I opened the same file that I created in the previous step. Once done, head to “Insert -> Text” to add some text. For example, I added the following text to the PDF:

Head to Insert->Text to add some text.

You can also adjust the properties of the edit from the options present at the right hand side of the window.

In addition to text, the editor lets you add images as well – just go to “Insert -> Image” in case you want to add one. Just like text, you can also adjust the properties of images.

Add radio buttons and checkboxes

You can also use the Master PDF Editor to add radio buttons as well as checkboxes to PDF files. To do so, head to the “Insert -> Radio button” and “Insert -> Check box” options, respectively. For example, I added both to the PDF I had created:

Add radio buttons as well as check boxes.

Similarly, you can perform these and many more edit actions, including adding combo box, list box, buttons, signature, and more, on any existing PDF file.

Note: we’ve already discussed how to create PDFs with fillable forms in LibreOffice. It’s worth mentioning that you can do the same using Master PDF Editor, too – the Edit Box, Check Box, Radio Box, and more, options present in the “Insert” menu will help you achieve that.

You can also use the Master PDF Editor for editing existing files. For example, here is a PDF file that I opened in the editor by heading to “File -> Open.”

Now, suppose the requirement is to highlight the text “port number.” To do that, first select the option “Comments -> Highlight Text”

Select the option 'Comments -> Highlight Text.'

and then use the cursor to select the text you need to highlight.

Use the cursor to select the text you need to highlight.

As you can observe, the text got highlighted. Similarly, to underline text, first select “Comments -> Underline Text”

To underline text, select 'Comments -> Underline Text.'

and then use the cursor to select the text you want to underline.

Use to the cursor to select the text you want to underline.

As you can see, the column headers “Applications” and “Port numbers” were successfully underlined.

You can also use the Master PDF Editor to add text to an existing PDF file, something which you can do by first selecting the “Insert -> Text” option

Use the Master PDF Editor to add text to an existing PDF file.

and then clicking at the point in the PDF where you want to add text. For example, I added the text “(We’ll talk about this later)” just after the highlighted text.

Aside from these, the editor provides a bag full of options that you can use while editing an existing PDF file.
