How it works

Complete the job in three clear steps

  1. Choose a DRM-free MOBI or AZW3 ebook from this device.
  2. Let the pinned browser parser read its metadata and chapter structure locally.
  3. Review the result and download the generated text, HTML, EPUB, report, or cover file.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Practical details

Lucaden uses the MIT-licensed foliate-js parser at an immutable GitHub commit for legacy MOBI and KF8/AZW3 input. TinyWow is credited only as a feature-parity reference; its application code is not copied.

Questions

About this tool

Does Lucaden upload my Kindle ebook?

No. Parsing, extraction, sanitization, and packaging run in temporary browser memory.

Can it open an Amazon purchase protected by DRM?

No. Lucaden does not remove or bypass DRM. Use only unencrypted ebooks you own or are authorized to process.

What should I verify after conversion?

Plain text intentionally removes images, links, tables, typography, and page layout. Section boundaries may differ from printed chapters.
