A popular software that you can use to edit and write PDF files with all the necessary functions similar to a word document is Adobe Acrobat Reader. While Adobe Acrobat Reader is primarily known as a PDF reader, the software also includes a wide range of editing capabilities.

To download Adobe Acrobat Reader for free, you can follow these steps:

1. Open your preferred web browser and visit the official Adobe Acrobat Reader download page.
2. Ensure that the "Optional offers" are unchecked to avoid installing any additional software during the installation process.
3. Click on the "Download Acrobat Reader" button to start the download.
4. Wait for the software to finish downloading and then locate the downloaded file on your computer.
5. Double-click on the downloaded file to run the installer.

Once installed, you can use Adobe Acrobat Reader to open and view PDF files. To edit and write in PDF files using Acrobat Reader, you'll need to subscribe to the paid Adobe Acrobat DC plan, which provides advanced editing functionalities. However, please note that the free version of Adobe Acrobat Reader offers limited editing capabilities such as adding comments, highlighting text, and filling out forms.
