Limitations
.EPUB — Limitations
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.
.PAGES — Limitations
- Apple-only — Windows and Linux users cannot open .pages files.
- Binary IWA format is opaque — no third-party tooling.
- Track changes and collaboration features lag Word and Google Docs.
- DOCX round-trips lose some Apple-specific styling.
- Macro support is minimal (no VBA equivalent).
Frequently Asked Questions
EPUB (Electronic Publication) is the open standard eBook format maintained by the W3C. It supports reflowable text that adapts to screen size, embedded fonts, images, and interactive content, making it the most widely supported eBook format globally.
PAGES (Apple Pages) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.
EPUB files open in Apple Books, Google Play Books, Calibre (free), Kobo eReaders, and Adobe Digital Editions. Note that Amazon Kindle does not natively support EPUB, so conversion to MOBI or AZW3 is needed.
Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most PAGES files with reasonable fidelity. If your installed software does not support PAGES, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.
Use EPUB for reading on phones and eReaders since it reflows text to fit any screen. Use PDF for documents with fixed layouts like textbooks with precise formatting, scanned pages, or documents intended for printing.
Upload the PAGES to KaijuConverter and pick DOCX, PDF, ODT, RTF, HTML, Markdown, or plain text. Our pipeline runs LibreOffice headlessly plus pandoc for text formats — the same engines behind professional document pipelines. Styles, tables, images, and hyperlinks survive the conversion intact.
