- Click on the “Edit” menu.
- Choose “Search” or press “Cmd + F.”
- Select “All PDF Documents” and then choose your PDF folder.
- Type a word or phrase and click “Enter.”
- You’ll find search results in all opened PDFs. Now, you can go through all the displayed documents and find what you’re looking for.

- Insert your search query and click “Enter.”
- Search results will instantly display highlighted text, comments, and sticky notes.
Color coding is a quick way to sort through notes on PDFs when highlighting text using different colors. You can identify comments within a text if you know what color to look for. Let’s show you how:
- Go to “Menu” and click the “Annotations” tab.
- Scroll to locate the search field.

This same method can help you locate bookmarks and outlines within PDF files.

Sharing PDF files will make your information susceptible to danger, so it’s essential to secure PDF documents. Gratefully, there are several ways to protect your files without breaking the bank.
Most PDF editors allow you to password-protect or encrypt your files to control how people access your content. Other security controls to add to PDFs include customized watermarks, limited printing or sharing, and PDF tracking options.
Note that some security options are more advanced than others, and depending on your needs, you can choose the right security to install on PDFs. If you create or combine PDF files to share with friends and colleagues, passwords and encryption keys might be adequate security.
For sensitive file data within business contracts and government legislation, deploy higher security features. Options like electronic signatures, copyright protection, and DRM controls are locked within paid plans on a PDF editor.
How to annotate PDF files
You may ask, how can I annotate a PDF? A PDF annotator tool is useful for adding comments to a PDF file without altering the text. It’s possible to highlight, underline, strikethrough, or add sticky notes, shapes, and text boxes to a PDF.
To make comments like convert PDF to Word on a document or split PDF files into multiple PDF files, you can annotate it on the PDF.
Getting a specialized PDF annotator might be expensive, especially when you can afford a good PDF editor containing tools for annotation. There are two ways to annotate PDF documents with your device. If you don’t want to annotate PDF online, you can choose an offline editor to add comments faster.
- Upload your PDF to the editor.
- Click on the “Comment” tab and select “Annotate.”
- Select any tool on the “Annotation” tab to add comments.
- Save and download the finished document.
The downside of using an online annotation tool is that it may provide limited features compared to a PDF reader. An intuitive PDF editor like Lumin PDF offers many options on the annotation tab so that you can provide helpful feedback without making edits.
Most PDF reader apps let you split PDF file into two parts and add digital signatures as an advanced annotation feature at little or no cost.
