What Programs Allow You to Edit PDF Files on Mobile?

Perhaps you want to explore other options that allow you to edit PDF files on mobile without using our online tool? That’s fine. There is a plethora of software you can use to modify your files. Some are more user-friendly than others, but they all work fine.

Conversely, we’ll point out that an online editor is a shortcut to editing PDF files. So, we advise you only use the tools we’ll mention below if you don’t have any online options or if you’re more familiar with a particular tool compatible with your device.

How to Edit PDF File for free from Your Computer

Your computer can utilize the power and features that multiple software offer. And this remains true regardless of the operating system you’re using. So, whether you prefer Windows to Linux or macOS to either of them, you’ll still be able to edit your documents. Please have a read of them below.

Windows 10 and earlier versions of Windows

Microsoft Windows is one of the most versatile operating systems. Software like Foxit PDF Editor or PDF Element edit these files well.

These tools have a PDF edit button on their top toolbars, but you’ll have to pay a fee to access all their features and remove watermarks on the edited PDF files. So, be mindful of that before using them.


Mac computers and macOS are not as popular as Windows. But they still have an impressive library of tools for this specific task. A few notable ones are Acrobat Reader for Mac, Sejda PDF Desktop Pro, and Foxit PDF.

These efficient tools allow you to edit the PDF file right from the first interface when you load it into them, but they’re not free. So, you must pay if you want to scale the premium wall to access all their PDF editing features.


Linux is even less popular than Windows or macOS, so there are fewer applications for you, but LibreOffice Draw is a good one. But mind you, using this tool entails downloading and installing the entire LibreOffice Suite. And remember that the installation method for Linux distributions differs. So, how you install on Debian-based distros will vary from how you install on Arch-based distros.

All this makes editing PDF files on Linux more complex and, perhaps, inconvenient, so it’s an option you should choose only when necessary.

How to Edit PDF File from Mobile or Tablet

We already pointed out how you can edit PDF files on mobile, but know that you can do the same on tabs. However, some mobile devices might not be compatible with browser-based online PDF editing tools. Thus, you might have to install third-party apps to get the job done.


When it comes to Android, you have many apps to choose from. However, we recommend you give Xodo PDF Reader and Editor a try. We like it because you can even convert images to PDF. In addition, it automatically syncs with Dropbox and Google Drive to keep your edited PDF files safe.

iPhone (iOS) or iPad

The AppStore offers many apps to modify this file format, but they differ in functionality, size, and user-friendliness. PDFpen is the tool we recommend for editing files on iOS because it’s lightweight and offers multiple features. It’s not free, but it can do what you want.

So, this is where we’ll end. Editing PDF files online doesn’t have to be a long and arduous affair. Our online tool is quick and efficient at editing PDF files, so you don’t need third-party solutions. As long as you have a good or stable internet connection, you’re good to go!
