How to write to PDF from PC

Do you have a device equipped with Windows , macOS or Linux ? Whatever operating system you use, below you will find the main solutions that I recommend you consider for writing to PDF from PC .

Microsoft Word (Windows/macOS)

Do you have a subscription to the Microsoft 365 suite or do you have a classic copy of the Office suite ? In this case you will be happy to know that it is possible to write on PDF files using Microsoft Word , the word processing program par excellence included in the collection.

Are you asking me how to do it? Give me a minute and I’ll explain it to you in detail. First, open Microsoft Word and import the PDF you want to edit into it, using the File > Open menu .

Once this is done, click on OK within the warning that appears (about the possibility that the original layout will not be maintained), to convert the PDF document into an editable document within the program.

If you downloaded the PDF file from the Internet, it is possible that Microsoft Word, after converting it, enables the so-called Protected View , i.e. a mode that only allows the user to view the file, and not modify it, for security reasons.
To disable this protection, all you have to do is locate yourself on the yellow bar at the top of the document, click on Enable editing and immediately after on OK . Now, all you have to do is write and make changes in the file, as you wish, as if you were working on a Word file.

Once finished, choose whether to export the document as a Word or PDF file by selecting Save As from the File menu . On Windows there is also the File > Export menu which allows you to create a PDF/XPS document by pressing a specific option.

LibreOffice (Windows/macOS/Linux)

LibreOffice (Windows/macOS/Linux)

Don’t have Microsoft 365 installed on your computer or don’t have the slightest intention of signing up for a subscription to use it? Then don’t worry because, even in this case, I have the right solution for you. Have you ever heard of LibreOffice ? No? Then let me tell you about it in detail.

LibreOffice is a free, open-source productivity suite that contains word processor, spreadsheet, presentation, and database programs. In short, in short, it is an excellent alternative to Microsoft 365, as well as a more than complete solution. The good news doesn’t end there: in fact, it is compatible with all the main operating systems, such as Windows, macOS and Linux, and allows you to write to PDF for free .

How do you say? Can’t wait to start using this office suite? Then don’t waste any more time: visit the service’s website and follow the instructions I have given you in this article to download and install LibreOffice on your PC.

At this point, after having downloaded and installed the suite, regardless of the operating system used, you can start editing your PDF file by opening LibreOffice , clicking on Open file , in the window that opens, in the left sidebar, and selecting the document to edit.

Once this is done, you can modify the document as you wish by adding, removing, highlighting portions of text, inserting images and so on using Draw , the program for creating printable documents included in LibreOffice.

After completing the changes, you simply need to go to the File menu at the top right, select the Export as item , click on Export directly to PDF and choose the location and name to assign to the file. Finally, click Save to save it.

Adobe Acrobat Reader (Windows/macOS)

If you are willing to evaluate another program to achieve your goal, I cannot help but recommend Adobe Acrobat Reader . How do you say? Haven’t you ever heard of it? Really strange! This is the famous Adobe program for viewing and editing, albeit limited in this version, PDF format files of which Adobe, among other things, is the inventor.

To start using this software, visit the Adobe website and, depending on the operating system you are using, follow the instructions I have given you in this guide .

After downloading and installing the program, whether your operating system is Windows or macOS, all you have to do is open it, select the Menu item , at the top left, and click on Open , to choose the document to open.

Once this is done, you can use the tools at your disposal by clicking, in the tools menu located at the top right, on the speech bubble icon with the + symbol to add a comment, on the highlighter icon to highlight text, on the of the line to make a freehand drawing, on the dotted square icon to add text, fill in a box and add check marks, and on the pen icon to add a signature or add initials.

After completing the customization of your document, all you have to do is go to the Menu section , at the top left, click on Save as , choose the destination of the file and click on Save .

In case you need, for example, to modify part of the text present in the document, if possible, to add an image or so on, it is good that you know that it is necessary to subscribe to the Pro version of Adobe at the cost of 18.29 euros/month . However, it is possible to take advantage of a 7-day trial period during which you can use all the advanced features of the program for free. For more information, I recommend you read the article I wrote about how to download Adobe Pro .
