Reflowable Typography

HTML Structure to Reflowable MOBI Architecture

Webpages are written in HTML with cascading stylesheets, while MOBI is a compiled Palm Database binary format. ScanPDF utilizes Calibre's ebook-convert pipeline to translate semantic HTML markup into reflowable PalmDOC chapters optimized for e-ink reading hardware.

1

Heading & Hierarchy Translation

Converts <h1> through <h6> headers into structured chapter dividers, generating navigational bookmarks for e-reader tables of contents.

2

Inline Styling & Lists

Preserves bold, italic, underline, bulleted lists, and ordered sequences while stripping extraneous website sidebars and web boilerplate.

3

Image Asset Embedding

Extracts embedded base64 and local image references, packing them directly into the MOBI record stream to prevent broken 404 links.

Legacy MOBI Characteristics & Hardware Compatibility

Legacy Kindle Sideloading

MOBI is a legacy format created by Mobipocket. It is ideal for direct USB transfer to older Kindle generations (Kindle Keyboard, DX, 4th gen) and legacy readers.

Send-to-Kindle Note

Amazon has phased out MOBI for wireless 'Send to Kindle' delivery. For modern Kindles via cloud delivery, consider our HTML to EPUB or HTML to AZW3 tools.

Zero Persistent Storage

All files execute in request-scoped temporary directories. Neither source documents nor generated MOBI binaries remain on disk after delivery.
