The Last-Mile Solution

Integrated Desktop Editor for 100% Flawless EPUBs

AI OCR handles complex layouts and math formulas, but standard converters leave minor errors behind. ReflowablePDF gives you an in-app desktop editor to fine-tune text and structure before exporting.

Visual Text Proofreading

Directly edit text blocks on the preview canvas to fix OCR typos, missing punctuation, or minor misreadings in seconds.

Noise Cleanup & Exclusion

Click to remove unwanted image noise or misplaced elements. Undo deletions anytime or exclude specific pages from export.

Custom TOC & Hierarchy

Promote or demote chapter headings (H1/H2/H3), search text to insert new table of content nodes, and keep your eBook organized.

Typography & Cover Controls

Select your preferred cover image, toggle Serif or Sans fonts, and fine-tune font size percentage and line height for e-readers.

No complex third-party tools required

Forget exporting broken HTML into Sigil or Calibre. ReflowablePDF combines AI OCR extraction with an instant proofreading workflow so you export publication-ready EPUBs directly.
