How to Split a PDF Online — Step by Step
Upload your PDF
Drag and drop your PDF file onto the upload area, or click to browse. The file is loaded entirely in your browser — not uploaded anywhere.
Choose a split mode
Select Range, Pages, or Size mode. Use Custom ranges to define exactly which pages go where, or Fixed to auto-split every N pages. Pages mode lets you pick specific page numbers.
Configure your ranges
In Range (Custom) mode, set from/to page numbers for each range. Click '+ Add Range' for more. In Fixed mode, enter the number of pages per chunk.
Split and download
Click 'Split PDF'. The output files appear immediately. Download each file individually or click 'Download All as ZIP' to get everything at once.
Custom Page Ranges
Define exactly which pages go into each output file. Create up to 10 custom ranges — for example, pages 1–5 in one PDF and pages 6–12 in another.
Fixed Interval Splitting
Automatically split a PDF into equal chunks. Choose 'every N pages' and the tool creates all the files at once — ideal for splitting reports, invoices, or books into chapters.
100% Private & Client-Side
All PDF processing uses the pdf-lib library running entirely in your browser. Your document is never uploaded, sent to a server, or accessible to any third party.
Common Use Cases
Extract Specific Chapters
Pull chapters from a large book or report PDF. Define a custom range for each chapter and get separate, properly sized PDF files for each section.
Invoice & Document Processing
Split multi-page batch PDFs generated by accounting or ERP systems into individual one-page invoices or statements — each as its own file ready for distribution.
Presentation Splitting
Divide a large slide deck or presentation PDF into sections by topic. Share only the relevant section with each audience without exposing the full document.
Academic & Research
Split scanned papers, thesis documents, or research compilations by chapter or section. Extract specific pages for citation, annotation, or sharing with collaborators.
