The PDF gathers all these elements and compresses it to a smaller whole. This allows for a smaller file size while retaining all the formatting and layout.

How to Open and Access PDF Files

To access PDF files, you can use a web browser to open and view its contents. You can do this when you right-click a PDF file and click on Open With. From there, select your browser and it will open the file as if it was a page.

The best method is to use a Reader app, such as the official Adobe’s Acrobat Reader. Opening a PDF this way gives you more options and functions.

You can also open PDF files directly through your browser.

How to Create and Edit PDFs

In editing PDFs, you need a program that lets you access those functions. Acrobat DC has a premium paid function that enables those features. Other programs like PDF-XChange Editor also provide such options.
