17 tools. No ads. No subscription. No account required.

🔀 INTERLEAVE PDFS — OUR SIGNATURE FEATURE

The only Android app built specifically for alternating-page merging. Perfect for duplex scanner users: scan the front pages, scan the back pages, then merge them into the correct reading order automatically.

✓ Mix pages from two PDFs in sequence — odd from one, even from the other
✓ Reverse order support — fix backwards scans in one tap
✓ Works with PDFs of unequal page lengths
✓ Live preview before saving

📄 MERGE PDFS & IMAGES

Combine multiple PDF, JPG, and PNG files into a single document in any order. Drag and drop to rearrange before saving. No file count limits.

✂️ SPLIT PDF — THREE MODES

Break any PDF into exactly the pieces you need:
✓ By custom page ranges — optionally merge all ranges into one output file
✓ Every N pages automatically
✓ Extract every page as its own separate PDF

🔄 REARRANGE PAGES

Full drag-and-drop page management using a visual thumbnail grid. Rotate individual pages (90°, 180°, or 270°), delete or duplicate them, then drag to any position. Every action is undoable — rotate, delete, duplicate, or move.

🧹 REMOVE BLANK PAGES

Automatically detect and remove empty or near-blank pages from scanned documents. Preview every flagged page before confirming removal — nothing is deleted without your approval.

🖼️ CLEAN SCAN

Remove yellowed and discoloured backgrounds from scanned PDFs — ideal for ink-saving reprints of old documents, photocopied papers, or faded receipts. Smart Auto mode adjusts whitening dynamically per page. Manual mode gives you direct brightness and contrast control. A live before/after preview shows the exact result before you save.

✍️ REMOVE ANNOTATIONS

Strip comments, sticky notes, arrows, highlights, and markup objects added by PDF editors — including Mac Preview, Adobe Acrobat, and others. Share clean copies without exposing internal feedback or review markups.

⚡ COMPRESS PDF

Reduce file size for email or storage. Three levels: Low (preserves image quality), Medium (balanced), High (smallest possible size). You choose the trade-off.

🔒 PROTECT & UNLOCK PDF

Add 128-bit password encryption to any PDF in seconds. Or remove protection from documents you own — without needing a separate tool.

📷 SCAN DOCUMENTS & BUILD PDFS

✓ Scan physical pages directly with your camera (ML Kit-powered)
✓ Convert JPEG, PNG, or WebP images into a PDF — configure layout, page size, orientation, margins, and compression
✓ Export individual PDF pages as high-quality JPG images

🔢 MORE PDF TOOLS

✓ Page Numbers — choose position, format, font size, and colour, with live preview
✓ Watermark — text or image, with opacity, rotation, and position control
✓ Flatten PDF — rasterise all content, or form fields only
