What Is PDF Splitting?
PDF splitting is an online tool that divides a single PDF file into multiple files. Extract only the pages you need from a large PDF, separate chapters into individual files, or share specific pages with others — it makes PDF management and distribution more efficient.
sakutto.ai's PDF splitter processes everything in your browser — your PDF data is never sent to any server. You can safely split confidential documents and files containing personal information.
Supports page range specification and single-page splitting. Preview page thumbnails before splitting to accurately select the pages you need. Perfect for extracting sections from a report or assembling specific pages for an application. Free, no sign-up required.

- Choose a split mode: by page range, by fixed page count, or extract specific pages

Why PDF Splitter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your PDF files to any server — everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere — processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk — no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes PDF files in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No PDF files remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your PDF files externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your PDF files are made. This can also serve as documentation for your IT security team.
Frequently Asked Questions
Is my file sent to a server?
No. All processing happens entirely in your browser. Your PDF is never uploaded to any external server, so you can safely use this tool with confidential documents.
Does splitting affect PDF quality?
No. Splitting copies pages as-is, so text, images, and fonts remain identical to the original file.
What split methods are available?
Three modes are supported: (1) Split by page range (e.g., pages 1–3, 4–6), (2) Split by fixed page count (e.g., every 2 pages), and (3) Extract specific pages.
Can I download all split files at once?
Yes. When splitting produces multiple files, you can download them individually or use the "Download ZIP" button to get them all in one archive.
Can I split password-protected PDFs?
Password-protected PDFs are not currently supported. Please remove the password before using this tool.
