Paperfold - Offline PDF Tools

Jackz

About this app

Paperfold is a complete PDF toolkit that runs entirely on your phone. No sign-up, no accounts, no cloud - every file is created and edited right on your device and never leaves it. If your phone is offline, Paperfold still works perfectly. Because it has no internet permission at all, your documents simply cannot be uploaded anywhere.

Whether you need to scan a receipt, merge a few files, sign a contract, or black out sensitive details before sharing, Paperfold does it in a few taps — with a clean, fast, no-clutter design.

EVERYTHING YOU NEED, IN ONE APP

• Images to PDF — Turn photos into a polished PDF. Reorder pages, apply clean-up filters, crop, and choose the exact output size.
• Scan — Use your camera to capture pages and save them as a sharp PDF.
• Sign PDF — Draw or add your signature and place it anywhere on the page.
• Watermark — Add text watermarks with adjustable size, opacity and angle.
• Merge PDF — Combine several PDFs into a single file.
• Split PDF — Break a PDF into separate files or pull out the pages you need.
• Compress PDF — Shrink large files and see the exact size before you save.
• PDF to Images — Save any page as an image.
