Chapter splits
Every 20 pages, every 50 pages — useful for large books.
What it actually does
02
BY RANGE
Custom page ranges
Type "1-5, 6-10, 11-end". Each range becomes a PDF.
04
LOSSLESS
Vectors and fonts kept
OCR text remains searchable. Nothing rasterized.
How it works
- Open morph.cool/split-pdf in any modern browser.
- Drop the PDF. Pick a split mode: per-page, by range, or every N pages.
- Hit Split. pdf-lib runs locally and rebuilds the page ranges into new PDFs.
- Download the ZIP (or single PDF if only one piece). Files land in your downloads folder.
- The original is untouched. Nothing was uploaded.

Why people leave the upload-first PDF tools
Morph splits PDFs in your browser — pdf-lib parses, our code reassembles, the output writes locally.
Frequently asked
How does the split work?
pdf-lib parses the PDF in your browser. We rebuild the chosen page ranges into new PDF documents, preserving fonts, vectors, and metadata. Output is a ZIP of split files when there's more than one.
Three split modes — which?
Per page (every page becomes its own PDF), by range (e.g. 1-5, 6-10, 11-end), and every N pages (chapter splits, e.g. every 20 pages).
Does the file upload?
No. The whole pipeline runs in your browser tab. The PDF, the parsing, and the output all stay local. Sensitive PDFs (legal, medical, payroll) stay sensitive.
What about page count limits?
There is no Morph cap. Practical limit is your device's RAM — most laptops handle 1,000-page PDFs comfortably.
Is the visual quality preserved?
Yes — split is lossless. Vectors stay vectors, fonts stay embedded, OCR text remains searchable. We are not rasterizing.
Encrypted PDFs?
Password-protected PDFs need to be unlocked first (you provide the password) before splitting. The password never transmits.
