Tip: use the ↑ ↓ arrows to arrange files in submission order — cover page first, then the essay body, then the bibliography.
It is 11 PM and a history essay is due at midnight. Your pieces are scattered: the title page as a Word export (title.pdf), three phone-scanned pages of handwritten notes converted to notes.pdf, the bibliography from your reference manager (sources.pdf), and a feedback slip from the draft stage (feedback.pdf).
| Step | What you do | Result |
|---|---|---|
| 1 | Select all four PDFs in the drop zone | File list shows 4 files |
| 2 | Arrow title.pdf to position 1, feedback.pdf last | Order: title → notes → sources → feedback |
| 3 | Press Merge | One 12-page assignment-merged.pdf, ~2.1 MB |
| 4 | Upload to your portal before the deadline | Submitted at 11:04 PM ✅ |
If the portal rejects the file for size, run it through Compress PDF to Target Size and pick the exact size your portal allows.

| Screenshotting pages together | Yes | Yes | No, but quality loss |
Server-upload tools keep a copy of your coursework on someone else's machine. This page never receives your files at all — the privacy strip above is not a slogan, it is the architecture.
Yes — unlimited merges, every feature, forever. No trial, no daily cap, no watermark, no account. Student workflows often mean merging 10–20 files a night before a deadline, and this tool does not meter any of it.
No. Merging happens 100% in your browser with the open-source pdf-lib library. Your essays, scans and IDs never leave your device — which also makes it safe for coursework containing personal details.
Follow your brief: cover page first, then the essay or report body, then the bibliography, then appendices. Use the up/down arrows next to each file to set that order before merging — the final PDF follows your list exactly.
Yes, with one extra step: turn the photos into PDFs first with the free JPG to PDF tool on this site, then merge those PDFs here. Photos from a phone scanner work fine — just keep the same orientation for all shots.
Merging itself barely changes the file size. If your submission is too big, run the result through the Compress PDF to Target Size tool and pick the size your portal asks for. Always check the portal's own stated limit — it varies by university and course.
As many as your device can handle — there is no artificial limit. Most students merge 2 to 20 files; very large jobs just use a bit more of your device's memory.
Yes. Every page keeps its original size, orientation and content. A4 essay pages and letter-size scans can live in the same merged file with no conversion.
Merging is performed locally by the open-source pdf-lib library (v1.17.1); no file content is transmitted. Portal size limits vary by university — always follow the limit stated on your own course or application portal. Researched by PDFBuddyFree Team · Last updated October 23, 2026.
