Are you having trouble figuring out how to fill PDF forms? You aren't alone. This isn't just a common question -- it's an important micro-skill that every computer user should learn.

While there are many ways to do this, and many of those ways are easy, one of the simplest and most convenient ways is to fill PDF forms using nothing more than Google Drive. Since Google Drive is free for all, anyone can use this method, and since Google Drive is accessible on the web, you can do this from anywhere.

All You Need Is a Google Drive Add-On

Editing PDF documents is not a native feature of Google Drive. But what it cannot do itself, can be outsourced to Google Drive Add-Ons, which extend the utility of the cloud platform. So let's turn to an essential Google Drive add-on called DocHub that can help you sign, edit, and share PDFs from the cloud.

Drag and drop the PDF form into your Google Drive to upload it. Open the PDF form.

With your PDF form displayed, click the Open with option on top of the document. DocHub isn't installed yet so click on the Connect more apps link that takes you to the Web Store.

Search for DocHub. When the result comes up, hit the blue Connect button to install it to Google Drive.

Now, go back to your open PDF document again and this time select DocHub from the Open with menu.

When you open DocHub for the first time, it asks for permission to access your Drive. Allow it and DocHub opens the document within its own interface and converts all form fields into editable fields.

If necessary, use the DocHub toolbar to modify the PDF document. For instance, use the text tool to enter text anywhere in the document. On mouseover, you can see what each tool does. It is self-explanatory. An automatic grid line also helps with the visual alignment of any extra annotation you do on the document.

DocHub also has an option to insert your custom signature. Save it on DocHub and use it on all documents that require a signature. You can sign it from your phone, draw on your screen, and even use a pre-existing signature image.

The DocHub hamburger menu on the right has all the options to save, send, or share your filled PDF form. For instance, you can download it to Google Drive again and share or send it from there.

DocHub has free and paid plans. The free plan allows you to edit unlimited documents by sign five of them per month.

You Can Do Everything With PDFs on the Web

PDF is a universal document format and Acrobat isn't the only player in town. There are several tools online that can do everything with PDF documents. And if you love working in the cloud, then Google Drive can do a lot with the PDFs you store in it.
