PDF Splitter — Extract Pages, Split by Range or by File Size, 100% Local

Real-world use cases

• Pull one page out of a 60-page signed contract bundle

  Legal sent you `master-agreement-2026.pdf`, 62 pages of signatures, exhibits, and schedules. The client only needs page 38 — the indemnity rider — so they can send it to their insurer. Drop the PDF in, switch to "By page range", type `38`, hit split. You get `master-agreement-2026-p38.pdf` downloaded straight to your machine in under a second. No uploading the whole signed contract to a random web tool, no scanning-printing-scanning to "extract" the page, no asking legal to re-export. The page comes out byte-for-byte identical to what was signed, just standing alone.

• Split a scanned book into one PDF per chapter for Kindle

  You scanned an 800-page out-of-print reference book on the office Canon (350 MB output). You want one PDF per chapter so it shows up as separate items in your Kindle library and you can read chapter 7 without scrolling past six chapters of introduction. Open the table of contents, note the page ranges (`1-22, 23-58, 59-94, ...`), paste them comma-separated into "By page range", hit split. The tool emits a zip of 18 chapter PDFs, each named with its page range, ready to side-load to a reader app. The 350 MB file never leaves your laptop, which matters because your IT policy bans uploading scanned company-owned material to consumer cloud tools.

• Extract just the tax-deductible pages from a year of receipts

  Your accountant asked for "only the business-meal receipts" from a 240-page year-end expense bundle. You've already tagged the pages mentally (`4-7, 19, 28-31, 44, 67-70, 89, 102-105, ...`). Type the whole comma-separated range into the tool — it tolerates wide ranges, missing pages, single-page picks, all mixed. One click, one zip back with each range as its own labelled PDF. You forward the zip to your accountant; they import each chunk into their bookkeeping system as a separate document with a clean page-range filename, no manual splitting on their end.

• Carve a 40-page board report into per-recipient packets

  The quarterly board pack has a finance section (pages 1-12) the CFO presents, an ops section (13-25) the COO presents, a product section (26-34) you present, and an appendix (35-40) shared with everyone. Instead of mailing the whole 40-page PDF to four people who only care about their own twelve pages, run three splits: `1-12,35-40` for the CFO, `13-25,35-40` for the COO, `26-34,35-40` for yourself. Three zips, each with two PDFs (their section + the shared appendix). Less to scroll past in the meeting, less risk of someone pre-reading a section they shouldn't.

• Archive an e-signed contract one page at a time for the records system

  Your document management system (SharePoint / Notion / Confluence) is set up to store one PDF per contract page for fine-grained access control — finance can see the payment terms page, legal sees the indemnity page, sales sees only the cover. Drop the 24-page e-signed contract in, switch to "One PDF per page", hit split. You get a zip of 24 single-page PDFs, named `contract-p1.pdf` through `contract-p24.pdf`, ready to bulk-import into the records system with their page numbers preserved in the filename. One drag, one zip, instead of opening Acrobat 24 times.

Common pitfalls

• Mixing 1-indexed and 0-indexed page numbers. The tool follows Acrobat convention — page 1 is the cover. If you write `0-3` thinking it means "first four pages", the `0` is silently dropped and you get pages 1-3 instead. Trying to "skip page 1" should be written `2-`; writing `1-` includes page 1.

• Splitting a password-protected PDF, then discovering the chunks still won't open elsewhere. The tool reads PDFs with `ignoreEncryption` so it can parse owner-locked files, but if the document uses true user-password encryption the output PDFs inherit the unreadable state. Decrypt with `qpdf --password=…` first, then split.

• Trusting filename order alone to reassemble the original. Output names like `report-p1-3.pdf` and `report-p10-12.pdf` sort lexically as `p1-3` before `p10-12` only if your file manager does natural sort. Many systems put `p10-12` before `p2-4`. Either zero-pad your source ranges (`p001-003`) or use the PDF Merger tool which re-orders by intent, not filename.
