Divide & Separate PDF Pages Offline - Split PDF Online
Split PDF files completely in your browser with this small tool. You can quickly split PDFs online without uploading by dividing them into equal-sized chunks, extracting each page to its own file, or specifying specific page ranges (e.g., 1-3,7,10-12). When you only need to safely split PDF pages, this quick, private, and cost-free solution is perfect.
How to Split a PDF with This Tool
Have a long PDF but only need certain pages? This tool lets you extract exactly what you need—right in your browser. No uploads, no sign-ups.
Step-by-Step
1. Drop in your PDF
Drag your file onto the area above, or click to browse. The tool reads it immediately and shows you the page count.
2. Choose how to split
You have three options:
- Page ranges: Type something like
1-5, 10, 15-20to extract specific pages - Equal chunks: Divide the PDF into a set number of equally-sized parts
- Every page: Separate each page into its own individual PDF file
3. Download your files
Download each split PDF individually, or grab all of them at once as a ZIP file. Files get descriptive names so you can tell them apart.
Common Uses
- Extracting chapters: Pull specific sections from a long report or manual
- Sharing specific pages: Send just the pages someone needs instead of the whole document
- Removing unnecessary pages: Strip out cover pages, blank pages, or appendices
- Separating scanned batches: Break apart a multi-document scan into individual files
- Filing requirements: Some systems have page or file size limits—splitting helps you stay within them
Page Range Syntax
The range input is flexible. Here are some examples:
1-5— Pages 1 through 53,7,12— Just pages 3, 7, and 121-3, 10-15, 20— Mix of ranges and individual pages
Privacy
Your PDF stays on your device the entire time. The splitting happens in your browser's memory using JavaScript. Nothing gets uploaded to any server. Close the tab and all traces are gone.
Technical Details
Uses PDF.js (Mozilla's open-source library) to parse the PDF and PDF-lib to create the split output files. Handles documents with embedded fonts, forms, and annotations. Works across all major browsers and functions offline once loaded.
The Operation of the Split PDF Tool
The same efficient core that powers our conversion and merge tools is used for all local processing. The client-side parses the PDF, and the necessary pages are immediately copied into new, lightweight documents using pdf-lib.
Use Cases for Split PDFs
- Choose which pages to extract (for example, only pages 2, 5, and 9).
- Divide each page into a separate PDF.
- Split the PDF into sections of the same size (three files with roughly the same amount of pages, for example).
- Remove the appendices or trim the front matter.
Why Split Client-Side PDFs?
- Privacy: documents never leave your device.
- Speed: immediate output with no upload wait.
- Flexibility: a single user interface with numerous split modes.
- Offline ready: functions after cached assets.
Advice: To save memory, do targeted range splits on very big PDFs rather than exporting each page.
