How to open an EPUB on Android
Once you have an EPUB app installed:
- From the Files app: tap the .epub file — Android will offer to open it with your installed EPUB reader
- From Chrome/browser: tap a .epub download link — it saves to Downloads; tap the notification to open
- From Gmail/email: tap the EPUB attachment → tap the share icon → choose your EPUB reader
- AirDrop equivalent: use Nearby Share or send via Bluetooth/WhatsApp/Telegram
How to read a PDF on Android with adjustable fonts
PDFs on Android have fixed fonts — you zoom in but the text doesn't reflow to your screen width. Converting to EPUB first gives you adjustable text that wraps to any size:
- Open Chrome and go to toolkit.bot/pdf2epub
- Tap Upload PDF and select your file from Downloads or Files
- Wait 15–60 seconds for conversion
- Tap the download link — the EPUB saves to Downloads
- Tap the notification to open in Moon+ Reader, Google Play Books, or your chosen app
Convert your PDF to EPUB — open it in Moon+ Reader or Google Play Books on Android.
