What is Obooko?

Obooko is a free reading platform that gives you instant access to thousands of legal eBooks you can read online or download as PDF, EPUB, or Kindle files. After 15 years and 11 million downloads, the platform has been rebuilt from the ground up to offer a modern, distraction-free reading experience. With over 4,000 titles across 30 genres — from indie authors to NYT bestsellers — Obooko is ad-supported like YouTube, meaning readers never pay and authors still earn. No subscriptions, no proprietary formats, and no lock-in.

Who it's for

• Avid readers on a budget — anyone who wants unlimited access to quality books without paying a cent or signing up for yet another subscription.
• Device-hopping book lovers — readers who switch between phone, tablet, and desktop and want their reading position synced automatically across every screen.
• Format-flexible downloaders — people who prefer to own their books in open formats like PDF, EPUB, or Kindle, and want to keep them forever without DRM restrictions.

Key features

Instant browser-based reading

Open any book in the Obooko Reader directly from your browser — no app installation required. Your reading position is saved automatically and synced across all your devices when you're signed in.

Free downloads in three formats

Every title is available as PDF, EPUB, and Kindle. PDF preserves fixed layouts, EPUB reflows text to fit any screen, and Kindle files work seamlessly on Amazon devices. You keep the files forever.

Legal library with editorial curation

All 4,000+ titles are legally licensed for global distribution. The library spans romance, thrillers, YA, fantasy, non-fiction, classics, and more, with editor-curated selections and weekly additions.

Author-friendly publishing platform

Authors can upload their books for free, retain all rights, and reach hundreds of thousands of readers. The platform handles distribution in all three formats and provides detailed author pages with reader ratings.

What stands out

Obooko gives you thousands of free, legal books you can actually keep — no subscriptions, no DRM, no catch.

Most free book sites either lock you into a proprietary app, limit downloads, or operate in a legal grey area. Obooko sidesteps all of that. Every title is fully licensed, you can download and keep any book in the format you choose, and the ad-supported model means the platform stays free without forcing you into a subscription. The rebuilt reader with cross-device sync and dark mode makes it feel like a premium service — at zero cost.

Worth checking out if…

You love reading but hate paying per book or managing multiple subscriptions. Obooko is especially appealing if you want to build a personal library of DRM-free eBooks you can read on any device, or if you're an author looking to reach a large audience without giving up your rights.
