Exams are coming up and your course material is spread across dozens of files: the slides from every lecture, a course reader, exercises, past exam questions. With one PDF per subject you can study with less hassle: everything is in the right order, easy to search, and you can print it in one go.
How to make one PDF per subject
- Gather your files in one folder, and if you like, put a number at the start of each name (01-introduction, 02-…) so the order is right straight away.
- Open Merge PDF and choose all the PDFs for that subject at once.
- Put them in the right order by dragging them in the list.
- Click Merge and download your course as a single file.
Make it easier to find your way
- Cut unneeded pages with Delete pages: title slides, blank pages or a table of contents that’s repeated in every file. Just type the numbers, for example 1, 5-7.
- Keep only what you need with Extract pages, for example only the chapters you need to know for the exam.
- Add page numbers with Add page numbers. Then you can simply refer to “p. 143” in your summary or your study group.
- Some pages sideways or upside down? Straighten them with Rotate PDF.
Slides in PowerPoint?
You can merge PowerPoint files with each other, but not together with PDFs: all files must be the same type. If you have a mix, save the presentations as PDF first (in your presentation app, choose PDF under Save As or Export), then merge everything.
Want several slides on one sheet? Pages per sheet puts 2, 4, 6 or 9 pages on one sheet, or 3 slides with lines for notes.
Everything happens in your browser: your files aren't uploaded. Once you’ve opened the site online, most tools also work without internet, handy in the library or on the train.
Frequently asked questions
How many files or pages can I merge?
There’s no fixed limit. It depends on your device’s memory: a course of a few hundred pages usually works fine on an ordinary laptop. If a file is too large for your device, the tool warns you beforehand.
Can I still search the merged course?
Yes. The text stays selectable and searchable, so with Ctrl+F (Mac: ⌘+F) you can find a term anywhere in the course. For scanned pages that only works if the scan contains recognized text (OCR); you can add it with OCR PDF.
Can I merge my summaries in Word too?
Yes, you can merge Word files into one Word document. If you want them in one file together with your PDFs, save them as PDF first.
