PDF Splitter (Advanced)

📖 About this tool

PDF Splitter cuts one PDF into several according to a rule you choose. It is what you need when a 60-page scan has three pages a supplier should see, when a bound contract needs separating into per-chapter files for archiving, or when a stack of scanned invoices has to be submitted three pages at a time. Three cutting modes cover practically every case - every N pages, extract only the pages you list, or cut right after given pages.

Everything happens locally, so files holding customer lists, salaries or contract values never travel to a server. Each part can be downloaded on its own or collected into a single ZIP.

✨ Features

• Every N pages - enter 3 and a 10-page file becomes four parts (3/3/3/1).
• Extract pages - accept notation like "1-3,5,8-10"; consecutive pages merge into one file.
• Split after pages - enter "3,7" to cut after page three and after page seven.
• Auto cleanup - duplicate and out-of-order page numbers are normalised.
• Page count per part - the result list shows how many pages each file holds.
• Single or batch download - grab one part or the whole ZIP.
• Local processing - nothing is uploaded and it works offline.

🚀 How to use

1. Click Choose file or drag a PDF onto the dashed area, or load the 10-page sample.
2. Pick a split mode and fill in its parameter.
3. Press Split; the result list shows every file and its page count.
4. Download parts individually, or take everything with Download all as ZIP.

⚠️ Notes

• Password-protected PDFs cannot be split.
• Page numbers start at 1; anything beyond the last page is ignored.
• Parts keep the original page content, with no re-layout.
• Very large files (hundreds of megabytes) are limited by browser memory and may be slow.
