So the question is: How to annotate a PDF in the right way?
Reviewing a PDF can be lengthy and time-consuming. This is why a PDF annotator can be a rather convenient tool to suit all your needs. So what does it really do?
Instead of sending lengthy email explanations, use a PDF annotator. PDF Annotator simply lets you add sticky comments directly to the specific paragraph requiring edits. It saves hours of time and enhances collaboration.
What is a PDF Annotation?
PDF Annotation refers to adding comments within the PDF, so as to pinpoint and locate exactly where edits are required. To annotate a PDF, you can use features like:
- Sticky notes
- Text boxes
- Hand-drawing
- Underlines
- Highlighters
- Strikethroughs, and more.
While PDF annotators offer a variety of features to help you annotate, most of them have these annotation features as a common base to start with.
Therefore, if you’re just starting out with a zero budget, there are many online PDF annotators available for free, one-time use. All you have to do is Google “Online Free PDF annotator” Upload your pdf, Add comments, Click “Download.” Yes, it’s that simple.
However, depending on your needs, you can choose to invest in a PDF annotator that brings more to the table, with wider options and flexibility.
What are the Benefits of PDF Annotation?
PDF Annotation is far more suitable alternative against lengthy emails—to seek feedback and make edits on your PDFs.
Below are the exact benefits of PDF annotation:
- Get rid of multiple file versions: Since all your feedback is marked directly within the PDF, you don’t have to juggle multiple file versions. Manage feedback and resolve comments all in one place, without having to track/locate the correct file where edits are required.
- Set reminders, notifications, deadlines on priority: Reviewers can simply open your PDF, add comments, or answer questions, while you sit back and get notified right away. You’re in full control of what’s going on.
- Review online and send PDFs around: Annotate PDFs on your browser, mobile phone, or any other device, without having to sign in. Collect comments from multiple reviewers through a single share link.
