Frequently asked questions
- Is my eBook uploaded anywhere?
- No — the EPUB (a ZIP of XHTML files) is unzipped and rendered entirely in your browser.
- Are DRM-protected EPUBs supported?
- No, DRM-protected books can't be opened by any browser-based tool; only DRM-free EPUB files work.
- Can I bookmark my place?
- Your chapter position is kept only for the current tab/session — reload and start from the table of contents again.
- Is content sandboxed for safety?
- Yes, each chapter renders inside a sandboxed iframe so embedded scripts or styles in the EPUB can't affect the rest of the site.
- Does it work offline?
- Yes, once loaded once, install the site as a PWA to keep reading offline.
