Take Notes on PDF: Fortunately, nowadays it is increasingly possible to study on PDF: among professors who publish their lecture notes online, digitized notes, books, and papers that can be purchased digitally, the PDF format is increasingly common to replace the dear, old paper, both on school desks and in the classrooms of the university.
How to Take Notes on PDF
In particular, those who own an Android tablet or an iPad will find it particularly convenient to study from PDF on these devices. However, many users wonder: is it possible to underline on PDF? And take notes? The answer is yes, but there are some distinctions to make, which we deal with immediately.
Image PDF vs. Text PDF
The first thing to understand is that, even if there is some text in the PDF, it is not said that the document is actually composed of text: it could only be an image that contains writings. This occurs especially in the case of documents that have been scanned in PDF, for example in the event that a classmate has printed notes that have subsequently been scanned: in this case, it is as if it were a photo of the notes and not of a document typed on the computer.
For this reason, in PDFs composed of images, it is still possible to take notes but it is not possible to underline.

If you have an iOS or Android device, the first thing to do to study on PDF is to download Adobe Acrobat Reader.
At this point, the PDFs that you transfer to your device will be opened with Adobe Acrobat: to emphasize and take notes on PDF on iPad, iPhone or Android, what we are interested in is the second button, with the ballon and the pencil.
After clicking on it, we will find several buttons at the bottom, which are shown below:
- the ballon to add a note
- the highlighter to highlight text
- the crossed out character to cut text
- the underlined character to underline text
- the normal font to add text
- the pencil to draw on the PDF
- the tip of the fountain pen to add the signature
Keep in mind that, as we mentioned, you can add notes and draw on any PDF, but you can only underline or highlight if the PDF is composed of text.
