Alternatives To Make Changes In A PDF File

You can make changes to your document using FormatPDF’s online tool above. However, there are other ways to get the job done, and you may wish to explore some of these methods. Whether you’re using a PC or smartphone, or different operating systems such as Mac, iOS, Android, Windows or Linux, we’ve highlighted other options you can explore.

Options To Make Changes In PDF File On Your PC

Different operating systems throw up different options. The built-in programs included with both Mac and Windows offer some degree of editing, or for more extensive options, you can use a paid program to complete your task. Here are some of the options available to users of Window, Mac and Linux computers.


Windows users have a number of options available. Firstly, they can use the in-built default Windows PDF viewing and editing program. However, bear in mind that this program will only provide basic functions.

Secondly, and for more comprehensive editing, you can use Adobe Acrobat to make changes. However, Adobe Acrobat is a paid program, so there is a charge attached to using this option.

Alter your document in Adobe Acrobat by following the steps below:

  1. Open your file in Adobe Acrobat.
  2. Next go to “Tools” > “Edit PDF”. You will find options such as editing text, updating fonts or adding new text, as well as resizing images, annotating and adding a watermark.
  3. Don’t forget to click the “Save” button once you’re happy with the changes.


Mac users can use the built-in default program to make their changes. The PDF and image viewer, Preview, enables basic editing functions.

Similar to Windows users, Mac users can also use Adobe Acrobat for Mac, which will open up more comprehensive editing options. You can follow the steps above to make changes using a Mac.


Linux users can use the popular program GIMP to edit their documents. However, the program will only allow you to make changes one page at a time. Plus, you can only save your file in GIMP format, so you will need to revert back to PDF after you’ve finished using the program.

Options To Make Changes In PDF File On Your Smartphone

You can use FormatPDF on any device, including a mobile. However, there are other third-party apps that you can download to aid you with editing tasks. Whether using Android or iPhone, head to the device’s app store and you’ll usually find something to help with your task.


Head to the App Store and search “PDF editor” or similar and you can choose from one of the apps that come up. Download the app and then open your document to start making edits. There should be a toolbar within the app that will present different editing options. Choose the tool you’d like to use and get to work! Don’t forget to download your altered document after you’ve finished making changes.


The Adobe Acrobat Reader app is open to Android users, and enables you to comment, add a signature and fill out forms. With the Adobe Acrobat Reader app, basic editing is free.

However, if you want access to more extensive editing options such as altering text and organizing pages, you will need to pay to access features. Simply download the app, sign into your account and open the file you want to change. Tap the blue pencil to reveal different editing functions. Download or save your file when you’re finished.
