Split PDF

Split PDF into multiple files by page ranges, extract single pages or divide evenly.

Use Cases

Typical scenarios for Split PDF — see if it fits before you start

Manual by chapter & team

A 200-page manual must be split into 1-20, 21-50 etc. for different teams. Split PDF accepts ranges like `1-20,21-50,51-200` with preview, auto-names by range and triggers downloads one by one, handling hundreds of pages locally with no upload — for manufacturing and training distribution.

Key pages for approval

Legal only needs signature, amount and annex pages from a 50-page contract. Split PDF extracts `3,12,28-30` with range validation (out-of-range ignored), preserves fonts/vectors, and produces a lean file for the approval chain — for high-frequency contract flows.

Single-page for renaming & print

100 applications scanned into one PDF must be split into single pages for `name-id` renaming. Split PDF splits into N files in one click, supports drag order and page preview, chaining to rename/print — for academic and HR batch jobs.

How to Use

  1. Upload — Click or drag PDF/images to the dashed zone. Multi-file and large files (<100MB per batch recommended) are read locally only.
  2. Configure & process — Set pages, angle, password or quality, then hit “Calculate / Process”. Split PDF runs via WebAssembly and pdf-lib in your browser — no server queue.
  3. Preview & download — Check pages, size and thumbnails on the right, then download. Batch jobs download one by one; tweak and re-run if needed.

Tips & Notes

  • Page syntax: Use 1,3,5-7 or 1-10,15; empty means all. Out-of-range pages are ignored.
  • Privacy & size: Everything runs locally — no server upload. For large files, process in batches of 50–100 pages.
  • Fidelity: Fonts and vectors are preserved where possible. For scanned PDFs, run OCR/searchable PDF first, then convert.

FAQ

How to split by chapter or department?

Split PDF supports ranges like “1-20,21-50,51-200” with preview, ideal for 200-page manuals per chapter. After splitting, files are auto-named by range and downloaded one by one, handling hundreds of pages locally with no upload — for manufacturing and training distribution. Preview total pages first to avoid missing pages.

Extract only a few pages for approval?

Enter “3,12,28-30” etc., out-of-range is ignored, extracted pages keep fonts/vectors and can be forwarded. Ideal for legal needing only signature and amount pages, check thumbnails before extracting to avoid wrong pages.

Split to single pages for batch rename?

Choose “split to N files”, then batch rename and print with drag sort and preview. Suitable for 100 applications merged into one PDF needing “name-id” rename, check filenames and order before distribution.
