Why the page is in a frame
A book’s chapters are markup written by whoever made the file, and this site treats that as untrusted. Each section is assembled into its own document and shown in an iframe with no script permission and no access to this page. Scripts and event handlers are stripped before that, and the page’s security policy blocks any connection to another host — so a book cannot phone home about being read, even if it were written to try.
What to look for
- Does the contents list reach every chapter, and land in the right place?
- Do the images appear, and stay inside the page at phone width?
- Is the first section the cover, a title page, or chapter one?
- For a right-to-left book, does the direction look correct?
Questions
- Which formats can it open?
- EPUB, MOBI, AZW3 and CBZ files, and folders of page images. Protected books are recognised and refused.
- Do I need to install anything?
- No. The book opens in this browser tab. Nothing is uploaded and nothing is installed.
- Is it safe to open a book from an unknown source?
- Book markup is treated as untrusted: scripts and event handlers are removed, and each section is shown in a sandboxed frame that cannot run code or reach this page.
- Can I move between chapters with the keyboard?
- Yes. While focus is on the reader’s controls or its contents list, the left and right arrow keys move to the previous and next section.
