Project Gutenberg on iPhone

Project Gutenberg is a free public-domain ebook library. On iPhone, you can read in the browser, download an EPUB, or use a reading app that supports imports.

Use EPUB as the default download format for reading apps. Use leaf if you want built-in Gutenberg discovery, vertical-swipe reading, notes, journals, highlights, share cards, themes, and optional Pro sync. Use Apple Books for a simple built-in import path.

What Project Gutenberg is good for

Project Gutenberg is best for free public-domain books: classics, older nonfiction, poetry, essays, and obscure works that may not be easy to find in modern ebook stores. Its official site offers books that can be read online or downloaded in formats such as EPUB, Kindle-compatible files, plain text, and HTML.

Public-domain status depends on where you live. Project Gutenberg focuses on free ebooks, but readers outside the United States should check local copyright rules before downloading.

Download a Project Gutenberg EPUB on iPhone

Open Project Gutenberg in Safari.
Search for the title or author you want to read.
Open the book page and look for the download options.
Choose an EPUB option when you want the file to adapt to iPhone reading settings.
Use the iOS share or open sheet to open the file in your preferred reading app.
If you use leaf, you can also discover Project Gutenberg books from Explore instead of starting in Safari.

Which format should you choose?

EPUB is usually the best default for iPhone reading apps because it adapts to screen size, font settings, and reader controls. HTML is useful for quick browser reading, plain text is useful for simple text access, and PDF is best reserved for fixed-layout or special cases.

Where leaf fits

leaf is a good fit when you want Project Gutenberg discovery inside a dedicated reading app rather than a browser-only workflow. Its Explore tab can help readers find public-domain classics, and the reader supports EPUB, PDF, and Markdown imports.

It is also designed around vertical-swipe reading on iPhone. For longer classics, leaf adds reading journals, highlights, notes, passage and completion share cards, themes, fonts, custom fonts with leaf Pro, optional leaf Pro sync, and iCloud Book Vault.
