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 it 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.
