Learn how to edit a PDF on your iPhone from anywhere.

Whether you’re out and about, at the office or at home, it’s a cinch to make edits to PDF documents.

Your work life can be filled with PDFs from other contributors that require review and comments on your part. Your school life can also involve essays and other PDF documents that need tweaking to get just right.

From an essay for a school friend to a project with a work colleague, if you have a document to review you need the ability to annotate a PDF on iPhone with additions, deletions, changes, and comments. You can write freehand directly on a PDF, insert comments, and make more complicated edits and annotations.

You don’t need a desktop computer, special software, or even an app to make it happen.

No matter where you are, you can make that happen right on your iPhone with Adobe Acrobat online services.

Here’s how to edit PDFs on an iPhone.

Open Adobe Acrobat services in a browser and navigate to the edit PDF tool.

You will be prompted to sign in using a Google, Apple, or Adobe account.

Choose your PDF file on your iPhone.

• Start by tapping “Select a file,” which will allow you to navigate to the document you need, whether it’s saved on your phone or in the cloud.
• Choose your file and sign in.

Use tools to highlight, underline, or strike through text.

• Notice the vertical toolbar along the left side of the viewer. Click on an icon to view and select its functions from a dropdown menu. Whichever icon is currently highlighted is the function that will be applied to the next click of your mouse. The first icon is a typical mouse pointer or a hand icon that lets you click and hold to drag the entire image for easier viewing.
• You can also add text to the document, write comments, or place a sticky note. You can even draw on a PDF on iPhone to make freehand markups.

Download the PDF file to your iPhone.

• When you’ve finished editing, you can download the file or share it with others. To share, either get a link or send an email by choosing the option from the “Share” menu.
