About PDF Tools.

Contracts, bank statements, medical records and identity documents are exactly the files that should not be uploaded to an unknown server. PDF Tools is a complete PDF toolkit that runs entirely on the phone, so they never have to be.

It merges, splits and compresses documents, converts between PDFs and images, organises and signs pages, fills forms, scans with the camera and manages passwords. There is no upload, no account and no sign-up.

Every result is saved to a PDF Tools folder in Documents, and a History tab records what was run and what it produced.

Who it is for.

  • Sensitive paperwork

    Handling contracts, statements and records without sending them to a web service.

  • Forms and signatures

    Filling in a form and signing it on the phone.

  • Scanning on the go

    Turning paper into a PDF with the camera and pulling out its text.

  • Sharing large files

    Compressing scans and image-heavy documents before sending them.

What it does.

  • Merge and split

    Combine PDFs in the order you choose, or extract a page range, specific pages or every page.

  • Compress

    Shrink large scans and image-heavy files, with a size preview before committing.

  • PDF and images

    Convert a PDF to images, or images to a PDF.

  • Organise pages

    Reorder, rotate, delete and extract pages, and add page numbers.

  • Sign and mark up

    Draw, type or import a signature and place it on the page; fill forms, add a watermark or flatten a document.

  • Scan and OCR

    Scan to PDF with the camera, pull selectable text out of a scan, extract text and convert HTML to PDF.

  • Security

    Add or remove a password, unlock a protected PDF and edit document metadata.

  • Image tools

    Compress, resize and convert images, and inspect image metadata.

  • History

    Results are saved to Documents/PDF Tools, and the History tab keeps a record of each operation.
