Batch Split PDFs

Batch Split PDFs is a Windows desktop app by 3thousand30 for splitting a PDF into individual pages or fixed-size chunks — saved as separate files in an output folder.

Get it on Microsoft Store

Select a PDF. Choose pages per file. Split. Done.

How it works

Select a PDF — pick the PDF file you want to split
Choose pages per file — set to 1 to get one file per page, or N to group every N pages into one file
Choose an output folder — split files are saved here, named after the source PDF
Split — the app processes the PDF page by page and writes the output files

All processing happens locally on your machine. Your files are not uploaded anywhere.

Key features

Page-by-page split — extract every page as its own PDF
Chunk split — group every N pages into one file (e.g. split a 100-page PDF into 10-page sections)
Auto naming — output files are named document_001.pdf, document_002.pdf, and so on
Live preview — see the exact number of output files before you split
Skip existing — optionally skip chunks that already exist in the output folder
Local processing — no uploads, no account required, works offline
