EPUB — Intentionally Invalid (bad OCF mimetype)

EPUB 2.0.1 - Converter Twin (NCX + guide)

A plain EPUB 2.0.1 build of a two-chapter book: NCX navigation, an OPF guide with cover and text references, and the meta name="cover" convention. One third of a conversion set that also ships as EPUB 3 and FB2.

EPUB 2.0.1 - Cover by meta name="cover" Only (no guide, no cover page)

The cover convention that predates every standard way of doing it: a bare meta name="cover" pointing at a manifest id, with no guide reference, no cover XHTML page and nothing in the spine. For testing cover extraction against the messiest of the three EPUB 2 conventions.

EPUB 2.0.1 - NCX pageList with pageTargets

An EPUB 2.0.1 that records print pagination the older way: an NCX pageList of pageTarget elements pointing at anchors in the text. The EPUB 2 counterpart of the EPUB 3 page-list nav, and what a converter has to translate between.

EPUB 2.0.1 — E-book (NCX navigation)

A valid EPUB 2.0.1 e-book navigated by an NCX table of contents and an OPF <guide>, with a cover — the older EPUB edition. Paired with an identical EPUB 3 twin for testing EPUB2↔EPUB3 conversion.

EPUB 3 - Converter Twin (nav document + NCX fallback)

The EPUB 3 build of the same two chapters: an XHTML navigation document with an NCX kept for older readers, and the cover declared as a manifest property. The middle member of the EPUB2 / EPUB3 / FB2 conversion set.

EPUB 3 - Embedded Font, Adobe Obfuscated

The same book obfuscated the other way: Adobe's scheme XORs the first 1024 bytes with the sixteen raw bytes of the identifier UUID. Two schemes, two byte counts, two algorithm URIs - the pair that catches a reader which implements only one and assumes the other.

Use case: Conversion testing· Conversion set

EPUB 3 - Embedded Font, IDPF Obfuscated

The same book with its embedded font obfuscated by the IDPF algorithm: the first 1040 bytes are XORed with the SHA-1 of the whitespace-stripped unique identifier, and META-INF/encryption.xml declares it. Paired with the plain-embedding twin so a de-obfuscator can be checked byte for byte.

Use case: Conversion testing· Paired fixture

EPUB 3 - Embedded Font, Intentionally Invalid (obfuscation not declared)

An intentionally invalid EPUB whose embedded font is IDPF-obfuscated while META-INF/encryption.xml is missing, so nothing in the container says the bytes were scrambled. Intentionally invalid and clearly labelled - this is the real-world failure where a book silently renders in a substitute face.

EPUB 3 - Embedded Font, Not Obfuscated

An EPUB 3 that embeds a TrueType face through @font-face with no obfuscation and no META-INF/encryption.xml. The control member of the obfuscation set: extract the font and it is a working TTF.

EPUB 3 - Fixed Layout (pre-paginated, 600x800)

A fixed-layout EPUB 3: rendition:layout is pre-paginated, every page declares a 600x800 viewport, and all content is absolutely positioned. Paired with a reflowable twin carrying the same words, so you can see which of the two a reader is actually honouring.

EPUB 3 - Fixed Layout with Landscape Spread

A fixed-layout EPUB 3 that asks for synthetic spreads in landscape and pins each page to a side with rendition:page-spread-left and rendition:page-spread-right. For testing two-up spread rendering and the side assignment readers get wrong first.

Use case: Conversion testing· Conversion set

EPUB 3 - Fixed Layout with Portrait Orientation Lock

A fixed-layout EPUB 3 that requests a portrait orientation lock and suppresses spreads entirely. For testing whether a reader applies rendition:orientation, ignores it, or rotates the content anyway on a landscape device.

File: EPUB · Fixed Layout
Use case: Conversion testing· Conversion set

EPUB 3 - Fixed Layout, Intentionally Invalid (no viewport meta)

An intentionally invalid fixed-layout EPUB: rendition:layout says pre-paginated but no content document declares a viewport meta, so the canvas size is undefined. Intentionally invalid and clearly labelled - for testing validators and the fallback a reader picks when it has no dimensions to scale to.
