Best PDF Tools for Students: Merge, Annotate, Compress, Cite
Students most often need to merge scanned readings into one file, compress large lecture-slide PDFs for upload portals with size limits, annotate and highlight source material, and occasionally convert a PDF back to an editable format for citations or quotes. All four are covered by the Merge PDF, Compress PDF, Edit PDF, and PDF to Word tools — free, with no account and no watermark.

Combining scanned readings and handouts
Course readings often arrive as separate scanned PDFs per chapter or article. Use Merge PDF to combine them into one file per course or unit — much easier to search and annotate than a dozen separate files.
Getting under an upload portal's size limit
Many university submission portals (Canvas, Turnitin, Blackboard) cap file size well below what a scanned assignment or slide deck can reach. Compress PDF with a target size matching your portal's stated limit solves this reliably.
Annotating and highlighting readings
Edit PDF & Add Signature covers adding text notes and marks directly on a source PDF — useful for annotating readings without printing them.
Pulling a quote or citation into a paper
When you need exact, copyable text from a source PDF for a citation and the source has no selectable text layer (a scanned book chapter, for example), run OCR PDF first, then copy the text you need directly.
