eBook conversion where structure is the product
We convert manuscripts into semantically rich, validated, and accessible eBooks that reflow predictably, validate strictly, and are ready for distribution at scale.
Everything you need for Advanced eBook Conversion, without the gaps
We handle the whole chain so you do not have to stitch vendors — and we show our work at each step so you can trust it.
XML/HTML5 conversion
Semantic markup — not just styled — with valid, well-formed output and meaningful hierarchy for navigation and accessibility.
DTD / Schema & CSS
Production to your DTD or ours, with CSS architectures that degrade gracefully across readers and apps.
MathType & math
MathType, LaTeX, or MathML with accessible alternatives, rendering consistently in fixed and reflowable contexts.
Fixed-layout & reflowable
Children's, comics-style, or standard reflowable builds — templated for series consistency.
Metadata & distribution pack
ONIX, manifest, and retailer validation so uploads pass first time.
QA & acceptance
EpubCheck, Ace by DAISY, and manual device matrix testing before delivery.
A team that has done this before — and learned where it breaks
We keep the parts that consistently improve outcomes and remove the theatre that only looks good in a pitch deck.
Validate early, not at the end
We run linting and validation continuously, catching structural drift when it is cheapest to fix.
Math without magic
Equations are accessible and searchable, not images of math.
One source, many outputs
Single structured source produces EPUB, Kindle, and web reader variants without rebuild.
Four steps, no black boxes
Map & sample
We map your house DTD/schema, convert a sample, and agree on CSS and math policy.
Convert & style
Batch conversion with automated enrichment and human spot-checks.
Math & media
Math and media are handled in dedicated passes and validated independently.
Validate & deliver
EpubCheck and Ace reports fixed, device matrix tested, distribution pack delivered.
XML/HTML5
Clean, semantic XML or HTML5 where every heading, list, figure, and aside has the right tag and class. We produce valid, well-formed files with consistent IDs for linking and cross-references, so navigation and accessibility tools behave predictably. Transformation pipelines are documented, so later corrections regenerate cleanly rather than accumulating manual fixes.
DTD / CSS
We work to your DTD, ONIX, or schema — or propose one if you need it — and build CSS as a maintainable system, not a one-off. Selectors are scoped, media queries are conservative for older readers, and print and digital share tokens where possible. Result: series books look like a series, and a mid-project style tweak does not require touching hundreds of files.
MathType
Math authored in MathType or LaTeX is converted to accessible MathML plus fallback images where readers require, with alt-text and linearization for screen readers. We test rendering in Apple Books, Kobo, Thorium, and Kindle pipelines, handling font fallbacks and line-break behaviour so equations reflow without clipping. Operator and variable styling follows your house notation guide.
