PDF Interleaver – Merge, Split, Rearrange & Secure PDF Files
The all-in-one PDF toolkit for Android. Merge, interleave, split, compress, rearrange, clean, password-protect and unlock PDF files — all 100% offline, with zero cloud uploads and zero ads.
WHY PDF INTERLEAVER?
Most PDF apps either require an internet connection, lock features behind a subscription, or bombard you with ads. PDF Interleaver does none of that. Every operation runs locally on your device, keeping your documents completely private.
🔀 SMART PDF INTERLEAVING — Our Signature Feature
Built for the task no other Android app does well: merging duplex-scanned documents by alternating their pages.
✓ Alternate pages from two PDFs — odd pages from one, even pages from the other
✓ Reverse order support — fix backwards scans in one tap
✓ Unequal page length support — seamlessly handles documents of different sizes
✓ Live page preview — see exactly how the result will look before saving
✓ Perfect for duplex scanner users, lawyers, accountants, and anyone who scans double-sided documents.
📄 POWERFUL PDF & IMAGE MERGE
✓Combine multiple PDFs and images into a single file with full control:
✓Merge unlimited PDF, JPG, and PNG files in any order
✓Drag-and-drop reordering for precise arrangement
✓Mix PDFs and images in one operation
✓No file count limits
✂️ SPLIT PDF — THREE FLEXIBLE MODES
✓ Break large PDFs into exactly the pieces you need:
✓Split by page range — define custom ranges and optionally merge them into one output file
✓Split at fixed intervals — split every N pages automatically
✓Extract all pages — save every page as its own separate PDF file
🔄 REARRANGE PDF PAGES
✓ Full drag-and-drop page management with a visual grid:
✓Drag pages to any position
✓ Rotate individual pages (90° / 180° / 270°)
✓ Delete unwanted pages
✓ Duplicate pages
✓ Undo any action — rotate, delete, duplicate, or move
🧹 REMOVE BLANK PAGES — CLEAN PAGES
✓Automatically detect and remove empty or near-blank pages from scanned documents
✓ Helps you save paper, avoid unnecessary prints.
✓AI-powered blank page detection using brightness analysis
✓Preview detected blank pages before confirming removal
✓Works on large multi-page scans in seconds
⚡ PDF COMPRESSION

✓Three compression levels: Low (best quality), Medium (balanced), High (smallest size)
✓ Fast, on-device processing
✓ No quality surprises — choose exactly what you need
🔒 PASSWORD PROTECT PDF
