About this app

Transform your PDF books into EPUB 3.3 files ready for more comfortable and adaptable reading.

TruePub reconstructs the editorial content directly on your device and verifies the integrity of the result before approving it. Your documents are never sent to external servers: the conversion works offline.

Key features:

• PDF to EPUB 3.3 conversion
• Local processing, with greater privacy, and offline functionality
• Optional language dictionaries: Portuguese and English are already included; other languages ​​can be downloaded whenever you want
• Preservation of compatible chapters, texts, and images
• Automatic content integrity audit
• Library of converted and approved books
• Interface in Portuguese and other languages
• No ads and no charge in this first version

The converter has been validated with real books of different sizes, structures, and page counts. When a file does not meet the quality criteria, TruePub informs you of the pending issue instead of presenting a result as approved.

Some scanned, protected, corrupted, or extremely complex PDFs may require additional processing. The final quality also depends on the structure of the original file.

Internet: conversion works offline. You can download public language dictionaries. The Google ML Kit, used in OCR, may send technical device and app data, installation identifiers, and performance metrics to Google for usage diagnosis and analysis via HTTPS. The content of your documents is not sent. See our privacy policy.

Dictionaries: FrequencyWords (Hermit Dave), CC BY-SA 4.0 license.

TruePub — your books, free to read.
