How it works
- Every page makes one single-page PDF per page. Custom ranges lets you carve out specific chunks (e.g. chapters). Every N pages splits into evenly-sized batches. Split in half divides the document down the middle.
- Each resulting PDF appears as a card below — click any card to download it individually, or use "Download all".
- A short ad plays before your download starts — it helps keep this tool free. Processing itself happens instantly; the ad is just a brief pause before the file downloads.
- All processing happens locally in your browser using pdf-lib — your files are never uploaded anywhere.
Split a PDF into separate files — by page ranges, every N pages, or one file per page — entirely in your browser. Your document is never uploaded, so it stays private.
Frequently asked questions
Is my PDF uploaded to a server?
No. Splitting happens locally in your browser using the PDF engine, so even confidential documents never leave your device.
How can I split the file?
By custom page ranges (for example 1-3 and 7-9), by a fixed chunk size (every N pages), or into one file per page — whichever matches your task.
Is there a file-size or page limit?
There's no fixed server limit because it runs on your device; very large PDFs simply use more of your device's memory, so extremely big files may be slower on low-memory devices.
Will splitting reduce quality?
No — splitting copies the original pages exactly, so text stays selectable and images keep their original resolution.
