How to Find Free Ebooks Legally: Project Gutenberg and Beyond

Thousands of classic books are free and legal to download, but finding the right book in the right format for your device is confusing. Formats, devices, and sources all use different names. This guide shows you how to find free ebooks legally, which format fits your device, and how to search across the largest free collection.

Why so many ebooks are free and legal

Books enter the public domain when their copyright expires, which varies by country but often happens decades after the author’s death. Project Gutenberg, the largest free ebook collection, offers tens of thousands of public domain books, from Jane Austen to Charles Dickens to Sherlock Holmes. These books are free because nobody owns the copyright any more, not because they are pirated. Downloading them is legal, and sharing them is legal too.

Pick the right format for your device

EPUB. The standard format for most readers and apps, including Apple Books and most Android readers. Text reflows to fit your screen.
MOBI or AZW3. The older Kindle formats. Newer Kindles also accept EPUB sent through Amazon’s Send to Kindle service.
PDF. Works everywhere, but text does not reflow, so it is hard to read on a small phone screen.
Plain text. Works on any device, but has no formatting, chapters, or cover.

When in doubt, download EPUB for a phone or tablet, and use Send to Kindle for a Kindle. The format matters more than the source: the same book in the wrong format is frustrating to read.

Find a book in four steps

Search by title or author. Use the free ebook finder below, which searches the Project Gutenberg collection.
Check the edition. Some books have several editions. Pick the one with a clear description and a recent update.
Pick your format. Choose EPUB for most devices, or the Kindle format for a Kindle.
Send it to your device. Download directly on your phone or tablet, or email it to your Kindle address.

Beyond Project Gutenberg

Other legal sources include your local library’s ebook app, which lends current books for free with a library card, and university collections that publish public domain works. Open Library lends scanned books, and many authors offer free short stories on their own sites. Stick to these legal sources: pirate ebook sites often carry malware, poor scans, and broken formatting, and they harm authors who still depend on sales.

Build a reading habit with free books

Start with one classic you have always meant to read, not ten books at once. A short book finished beats a long book abandoned. Use your reader app’s progress and bookmark features, and keep a simple list of books you want next. Free books remove the cost barrier, but the habit still needs a regular reading time, even ten minutes a day.

Search free ebooks with the tool

The free ebook finder below searches Project Gutenberg by title or author. Type a book or writer you want, pick the format for your device, and download it. Classic literature, free and legal, in under a minute.

Free ebooks for children and students

Free ebooks are excellent for children and students, because classic children’s books are widely in the public domain. Alice in Wonderland, The Jungle Book, and the works of Beatrix Potter are all free and legal. For students, public domain texts include Shakespeare, Jane Austen, and many history and science classics that appear on reading lists. Check whether your school or library recommends a particular edition, since older editions sometimes use outdated language or lack notes. A free ebook on a phone or tablet also means a student can carry a whole reading list in one device, which is lighter than a bag of paperbacks and far cheaper than buying every title new.
