PDF converter

An offline PDF converter for Android

Most converters ask you to upload your document to a website. PDF Reader does the conversion on your phone: the Word engine, the text-recognition models and the image pipeline are all built into the app.

Image to PDF and PDF to image

Image to PDF takes photos from your gallery or camera and makes each one a page, in the order you arrange them. Choose A4, Letter or Fit image, and whether each photo is contained or stretched to the page.

PDF to image renders pages as PNG or JPEG. Pick the resolution (higher is sharper and larger) and JPEG quality, and export every page or just a range such as 1-3, 5.

PDF to text with OCR

PDF to text reads the words out of a PDF — including scanned pages — with text recognition that runs on your phone. Read every page or name the pages you want, then copy the text, share it or save it as a .txt file.

Choose the language of the text: English and Latin-script languages (Spanish, French, German, Portuguese, Indonesian and more) or Hindi and Marathi (Devanagari, with English words on the same page). Gujarati, Tamil, Telugu and Arabic text can't be recognized yet.

Make scanned PDFs searchable

Make searchable recognizes the text on scanned pages and adds it invisibly, so the PDF can be searched, selected and copied while the pages look exactly the same. Pages that already have text are skipped, so nothing is added twice, and your original is not modified.

Step by step

How to convert a file

  1. Open the Tools tab and pick the conversion — for example Word to PDF or PDF to image.
  2. Choose the file (or photos) and any options, such as page size or resolution.
  3. Start the conversion. The work happens on the device, so it runs without a connection.
  4. Open or share the result from the success sheet. Converted files are saved in the PDFReader folder.

Good to know

Before you start

  • No upload, no account

    Files never leave your phone to be converted, and there is nothing to sign up for.

  • About saving results

    When some tools finish, the app may ask you to watch a short video before the new file is saved. If you are offline or no video is available, the file is saved anyway — and your original is never changed.

  • Share straight in

    Share a Word file or photos from another app to PDF Reader to start Word to PDF or Image to PDF with the file attached.
