PDF Editing Tips for Students: Annotate, Highlight, and Organize Study Materials

Between assigned readings, lecture slide decks, and scanned handouts, most of a semester's material shows up as PDFs. A few small habits make the difference between a folder of dead-weight files and study materials you'll actually use when it matters.

Highlight and annotate directly in the reading

Rather than printing a reading to mark it up by hand, highlight key passages and add margin notes directly in the PDF. It's faster than printing, keeps everything in one searchable file instead of a stack of paper, and means your notes travel with the document if you switch devices.

Merge related readings into one file per topic

If a week's readings come as several separate PDFs, merge them into one file per topic or per week. It's much easier to study from one organized document than to hunt through a folder of a dozen similarly-named files right before an exam.

OCR your scanned notes and handouts

Handouts photographed or scanned from a professor's printed materials are often just images — not searchable. Running OCR on them turns your scanned notes into real, searchable text, so you can actually find that one concept you remember reading but can't remember where.

Reorganize slide decks exported as PDF

When lecture slides are shared as a PDF, reordering and deleting pages lets you strip out filler slides and rearrange content into the order that actually makes sense for review, rather than the order it was presented in.

Sign and submit forms without printing

Permission forms, waivers, and administrative paperwork that ask for a signature don't require printing and scanning — sign directly in the PDF and submit it digitally, which is faster and looks cleaner than a photographed signature on a printed page.
