How it works

Upload a PDF, choose how to split it — every N pages, or custom page ranges you define — and PDFly cuts it into separate files entirely in your browser. All the resulting PDFs are bundled into a single ZIP for download.

Good to know

Your file is processed entirely on your device — it's never uploaded to a server.
Custom ranges use 1-based page numbers, e.g. 1-3, 4-6, 7.
Works with any standard PDF, including scanned documents.
