Ebooks-Gratuit (EBG) is a free ebook search engine that helps readers discover public-domain digital books. Visitors can search a catalogue of more than 10,000 titles by book name, author, or ISBN, with results available for PDF and EPUB downloads. Rather than presenting itself as the source of every book, EBG aggregates search results from several established platforms: OpenLibrary, Google Books, Project Gutenberg, and the Internet Archive. This gives users a convenient starting point for finding books across multiple sources in one place.

The website features popular, recent, and random search suggestions to help users explore topics and titles, alongside a blog and FAQ. Its interface is available in English, French, Spanish, German, Italian, and Portuguese. Ebooks-Gratuit also provides information about its data sources, privacy practices, and terms of service, as well as a contact option. Book content is supplied by third parties, so availability and download details may depend on the source. Overall, EBG is designed to make searching for free digital books straightforward and accessible.
