A course pack arrives as one long PDF. The course runs week by week. Somewhere between those two facts sits a job nobody enjoys: cutting the pack into readings that match the syllabus, naming each part so students can find it, and getting the parts to the right people at the right time. Done by hand — printing, scanning, or copying pages into new files one at a time — it eats an afternoon. Done with a split tool, it is a planning job first and a clicking job second.
Split PDF cuts one PDF into parts by page ranges, into even chunks, or into single pages, and delivers the parts as one ZIP. For weekly readings, ranges are almost always the right mode, because weeks follow chapters and topics, not equal page counts. This post walks through the whole routine on a fictional course pack, from syllabus to zipped handout set.
Start from the syllabus, not from the PDF
The mistake is to open the PDF and start cutting. Open the syllabus first and list what each week actually covers: the topic, the chapter or section, and any pages to skip. A week that covers "Chapter 3, sections 1–3 only" is not the same as a week that covers "Chapter 3." Writing the list down before touching the tool prevents the most common rework: a reading file that includes twenty pages nobody assigned.
Next, translate that list into PDF page numbers. This is where front matter bites. A textbook PDF often has a cover, a contents listing, and a preface before the numbered pages begin, so syllabus page 45 might be PDF page 57. The reliable method is slow but short: open the PDF, find the first page of each week's reading, and write down the number the viewer shows, not the number printed on the page. One pass through the document, noting start pages, is enough.
Also decide what to do with material that belongs to no week: introductions, glossaries, and appendices. A common approach is to split those as their own part — "reference" rather than "week 1" — so they are available all term without being mistaken for assigned reading.
Cut by ranges, then name parts for students
With the ranges mapped, enter one range per week into the range mode. A twelve-week course becomes twelve ranges, plus a reference part if you kept one. Each range becomes its own file, and the set downloads as a ZIP. Resist the urge to split week by week in separate sessions: one session, all ranges, one ZIP, keeps the parts consistent and avoids the version confusion of re-splitting the same source twice.
Naming is where many reading sets fail. A file called "part-3.pdf" tells a student nothing when it sits in a downloads folder next to eleven similar files. Rename the parts as you unzip them, using a pattern that sorts correctly and reads clearly, for example "week-03-photosynthesis.pdf" for a fictional biology course. Two-digit week numbers matter: "week-2" sorts after "week-10" in most file listings, while "week-02" sorts where it belongs. Keep the names short, lowercase, and hyphenated, and avoid spaces, which some older systems still mangle.
Check one part before distributing the rest. Open the first week's file and confirm it starts and ends where the syllabus says it should. If the boundaries are off, they are usually off by the same front-matter offset everywhere, and one correction to the range list fixes the whole set.
Worked example: a fictional 120-page course pack
Take a made-up course, "Introduction to Garden Science," taught by a fictional tutor, Dr. Ana Reyes, at Example College. The pack is 120 PDF pages: front matter on pages 1–6, then four units. The syllabus assigns Unit 1 in weeks 1–3, Unit 2 in weeks 4–6, Unit 3 in weeks 7–9, and Unit 4 in weeks 10–12, with the glossary (pages 111–120) as reference throughout.
Mapping syllabus to PDF pages gives these ranges: reference front matter is skipped for weekly files, Unit 1 spans PDF pages 7–36, Unit 2 pages 37–66, Unit 3 pages 67–90, and Unit 4 pages 91–110. But weekly readings need finer cuts, so within Unit 1 the tutor splits by topic: week 1 pages 7–16 (soil basics), week 2 pages 17–26 (water and drainage), week 3 pages 27–36 (plant nutrition). Repeating that pattern across all four units gives twelve weekly ranges plus one reference range for the glossary, pages 111–120.
After splitting, the ZIP unzips into thirteen files, renamed in order: week-01-soil-basics.pdf through week-12-final-project-prep.pdf, plus reference-glossary.pdf. Each file is small enough to email or upload to a course page on its own, and a student who missed week 4 can be sent exactly one file instead of the whole pack. If the tutor later reorders two weeks, the individual files move without any re-splitting — one advantage of cutting once and distributing parts, rather than re-cutting the source every time the plan changes.
Distribute in a way students can actually follow
However the parts travel — email, a course page, or a shared folder — send them with the syllabus week numbers, not just the files. A short list ("Week 1: soil basics, pages 7–16") lets a student check they have the right file without opening it. If the course page accepts only one upload per week, upload each part in its week; if it accepts a single ZIP, upload the whole set once and point students at the week they need. And keep the original unsplit pack somewhere safe: if a range turns out wrong mid-term, you can re-split from the original rather than trying to repair a part.
Honest limitations
Splitting does not understand content. It cuts where the page numbers say to cut, so a reading that ends mid-sentence because the topic continues onto the next page will still end mid-sentence. Check boundaries against the text, not just the chapter headings. Splitting also does not add page numbers, headers, or a "Week 3" label inside the file — the filename carries that information, so the naming step is not optional. If you need to fix page order or drop a blank page from a part afterwards, Organize PDF handles reordering visually, and Merge PDF can rejoin corrected parts.

FAQs
Should I split a course pack by ranges or by equal chunks?
By ranges. Weeks follow topics and chapters, which are rarely equal in length. Equal chunks would cut mid-topic and give some weeks far more reading than others. Use chunks only when equal size matters more than topic boundaries.
How do I handle front matter when working out page ranges?
Use the page number your PDF viewer shows, which counts from the cover, rather than the number printed on the page. Note the start page of each week's reading in one pass through the document before you split.
What should I name the split files?
Use a pattern like week-02-topic-name.pdf: two-digit week numbers so files sort correctly, a short topic word so the file is recognisable, and hyphens instead of spaces. Keep the pattern identical across all weeks.
Can I re-split later if the syllabus changes?
Yes, provided you kept the original unsplit pack. Re-split from the original with the new ranges rather than trying to cut or join the weekly parts, which risks losing pages at the joins.
