How to reflow a PDF on iPhone and iPad

Apple Books and Files show a PDF as a tiny printed page, so a two-column paper means pinch, zoom, drag, repeat. Reflowed, the text fits your screen in one column and you just scroll. Here's how.

Four steps

  1. Join the beta. PDFreflow for iPhone and iPad is in open beta on Apple's TestFlight. Install TestFlight from the App Store, then tap the App Store button below; it opens the beta.
  2. Open your PDF, whichever way is handiest:
    • tap Import in the app,
    • or, in Files, Mail or Safari, tap Share and pick PDFreflow.
  3. Read. It opens already reflowed. Scroll down; nothing to zoom.
  4. Make it yours. Font, text size, margins, colours and dark mode live in Settings.

What to expect

It's not perfect on every layout yet. If a page reads wrong, long-press the text and send feedback from the app. I read every report.

What it costs

The first 30 pages of every document are free. During the open beta, one tap unlocks the rest of a book, also free.
