Why Split PDFs on Android?

Android users often need to extract specific pages from large documents—whether it's pulling a single receipt from a bank statement, isolating a signature page from a contract, or breaking a massive PDF into email-friendly chunks. Traditional solutions either require downloading apps that request excessive permissions or uploading your sensitive documents to cloud servers.

Secure Mobile Processing

DocuStitch provides a zero-install, zero-upload solution that runs entirely in your Android browser using WebAssembly technology.

Step 1: Open the Tool in Chrome/Firefox

Navigate to DocuStitch on your Android device using Chrome, Firefox, or any modern browser. The WebAssembly engine loads automatically when you access the Split PDF tool.

  • No app installation required: Works directly in your browser
  • No permissions needed: Only accesses files you explicitly select
  • Works offline: Once loaded, you can disconnect and still split PDFs

Step 2: Select Your PDF

Tap the upload area to open your device's file picker. Select the PDF you want to split from Downloads, Documents, or cloud storage (Google Drive, OneDrive, etc.). The file is loaded directly into your browser's memory—it never touches our servers.

Privacy Verification

Test our privacy claim: Enable Airplane Mode after the page loads. The splitting will still work because all processing happens locally on your device.

Step 3: Choose Pages to Extract

Once your PDF is loaded, you can specify which pages to keep. Use simple syntax like:

  • 1-5 — First five pages
  • 3,7,12 — Specific pages only
  • 1-3,8-10 — Multiple ranges

Step 4: Download Your Split PDF

After processing (usually under 2 seconds), tap the download button. The new PDF is saved directly to your Downloads folder. The original file remains untouched—we create a fresh, optimized copy with only your selected pages.

Common Use Cases

  • Banking: Extract a single month from a multi-month statement
  • Contracts: Pull out just the signature page for sharing
  • Insurance: Split a claims packet into individual documents
  • Academic: Extract chapters from large textbooks or papers
