About this app

Merge PDFs and photos into one PDF. Every page sits on one board, so you see the result before you save.
Use it to merge PDF files into one, turn photos into a PDF on Android, or scan paper documents.
Free saves up to 3 pages per PDF. Plus saves any number of pages and makes files smaller.
No ads. No watermark, even on free saves.
Your files are handled on your device and never uploaded.

HOW IT WORKS
• Add photos, PDFs or a paper document you scan with the camera
• Every page appears on one board, photos and PDF pages side by side
• Touch and hold a page, then drag it into place
• Tap pages to rotate, duplicate, remove or save them back as photos
• Add a blank page wherever you need one
• Undo as many steps as you like, or reset to the start

PAPER AND SIZE
• Keep each page's own size, or fit everything to A4 or Letter
• Choose no margin, a thin one or a wide one
• Pick original, medium or small file size. Only photos get smaller; PDF pages stay sharp

PASSWORDS
• Open a password-protected PDF by entering its password
• Lock the PDF you save with a password of your own

PLUS
• Save any number of pages in one PDF
• Make files smaller
• 1 year $9.99 or lifetime $24.99

The subscription renews automatically until you cancel it. Manage or cancel it in Google Play.
