PDF is useful because it keeps the structure of a document consistent across different devices and operating systems. This becomes particularly important when a file needs to be shared with someone who may not have the same software used to create the original document. Converting documents to PDF can also make them easier to archive, print, or send as attachments. For straightforward PDF-related tasks, tools such as https://gurupdf.com can be another option to consider. It is still worth checking the final document after conversion, especially when the original contains tables, images, unusual fonts, or complex formatting that may not transfer exactly as expected.
