EPUB Production Tools
Cleaning, reflow, fixed-layout, and language tagging
InDesign EPUB Cleaner
Transform an InDesign-exported EPUB into a clean,
EAA-compliant EPUB 3 (or EPUB 2). Splits content into
chapters, removes InDesign noise, adds accessibility
metadata.
Reflow EPUB Cleaner
Defragments reflowable EPUBs by merging consecutive
<span> elements that share the same
attributes. Preserves HTML entities — ideal for
foreign-language text.
Fixed EPUB Cleaner
Consolidates absolutely-positioned text fragments in
PDF-origin EPUBs back into coherent text. Optional PDF
reference for best word-spacing results.
PDF Annotation → EPUB Tagger
Reads yellow highlights +
lang-XX comments
from an annotated PDF, then wraps the matching EPUB
phrases with proper xml:lang attributes.
