1. Compress before submitting
Most university submission portals cap upload sizes at 5–20 MB. A scanned assignment with photos can easily exceed that. The fix: compress your PDF before uploading. A 40 MB submission becomes 3 MB with no visible quality loss on screen.
Compress PDF →2. Merge multiple documents into one
Your dissertation might have a title page from one file, your chapters in another, and appendices in a third. Merge them into a single submission-ready PDF before uploading — far more professional than three separate attachments.
Merge PDFs →3. Make handwritten notes searchable
After lectures, many students photograph their notes or scan them. Those image-based PDFs are unsearchable. Run OCR to convert the images to real text — then you can Ctrl+F your way through an entire semester of notes before an exam.
Run OCR Free →4. Annotate PDF readings digitally
Printing 200-page journal PDFs wastes paper and money. Annotate digitally instead — highlight key passages, add text notes in margins, draw connections between ideas. All searchable, all saveable, all free.
Annotate PDF →5. Convert between formats
Professors send Word docs. Colleagues share PDFs. Online journals output PDFs. Your submission requires DOCX. The ability to convert in both directions — PDF to Word for editing, Word to PDF for submitting — is a basic student superpower.
PDF to Word →6. Scan handwritten work to PDF
Some courses require handwritten problem sets or lab reports submitted digitally. Use your phone camera and the YumPDF scanner (or JPG to PDF tool) to photograph each page and package them into a clean PDF submission.
JPG to PDF →7. Protect thesis drafts
Sharing a thesis draft with your supervisor via email is fine — but sharing it through a cloud link that anyone with the URL can access is risky. Password-protect draft documents before sharing outside controlled systems.
Protect PDF →8. Extract specific pages from reading lists
A 400-page textbook PDF and you only need chapter 6? Split the file and extract just those pages. Your device handles it faster, and sharing 15 pages with a study group is much cleaner than the whole textbook.
Split PDF →9. Add page numbers to long documents
A 50-page research report without page numbers is frustrating to discuss. "Look at the section about methodology" isn't helpful. Add page numbers before sharing any document longer than five pages.
Add Page Numbers →10. Watermark draft work
Circulating a draft paper for peer feedback? Mark it DRAFT so reviewers don't cite or quote the not-yet-final version. It's a five-second step that prevents potentially embarrassing citations of incomplete work.
