Question 1

Will the PDF look exactly like my e-reader renders the book?

Accepted Answer

No — and that is the honest answer. This tool REFLOWS the book onto fresh pages: chapter order, headings, bold/italic, lists, quotes, code blocks and tables are faithfully repainted as clean vector text, but CSS styling (fonts, colours, drop caps, columns) is approximated, and fixed-layout EPUBs (comics, picture books) render as ordinary reflowable text. What you get is a readable, printable, fully selectable document.

Question 2

Can it open DRM-protected EPUBs?

Accepted Answer

No — and it says so instead of failing mysteriously. Any book carrying META-INF/encryption.xml (Adobe DRM, and also packages with obfuscated fonts) is rejected with a clear message; decrypting protected books is not something this on-device tool does. Copy your own DRM-free EPUBs and they convert fine.

Question 3

Does it work with Hindi books?

Accepted Answer

Yes. Any Devanagari character switches the whole PDF to the embedded Noto Sans Devanagari subset, so हिंदी chapters, headings, lists and table cells render and stay selectable — and the Hindi table of contents (विषय-सूची) comes out in Hindi too. Latin-only books use the built-in Helvetica instead — nothing is embedded and the files stay tiny. One honest limit: the Noto face ships Regular only, so bold Hindi text renders at the same weight (headings still stand out through size).

Question 4

Where is my book processed, and what are the limits?

Accepted Answer

Entirely in this browser — a Web Worker thread unzips the package, follows the OPF spine and paints the PDF; nothing is uploaded, no sign-up, no watermark. One DRM-free .epub at a time, up to 20 MB. Chapter images that are PNG/JPG zip members are embedded at their spot (up to 50); remote http(s) images, other formats and inline images print as alt text, and every skip is counted honestly. Spine items that are not XHTML (covers, CSS, fonts) are skipped with honest accounting, and very large books are capped at 500 chapters / 60,000 blocks — the summary tells you when that happened.
