Automated Digital Conversion Pipeline

Our Professional Conversion Workflows

We leverage intelligent automation, structured preprocessing, and expert review environments to convert your publications with pixel-level precision and complete platform compliance.

Proprietary Conversion Engine

Fixed Layout EPUB (PDF-First Advantage)

Traditional Fixed Layout (FXL) EPUB conversion often depends on original source files such as Adobe InDesign packages, font files, and linked assets. In many real-world publishing scenarios, these source files are missing or corrupted, leaving only the final print-ready PDF.

Using intelligent PDF analysis and automated preprocessing, PUB BERRY SOLUTIONS transforms text-based PDFs into standards-compliant Fixed Layout EPUBs while preserving original design, typography, colors, and reading flow—without requiring original font files or InDesign packages.

Source PDF Preparation

Every FXL project begins with automated analysis of the supplied PDF to inspect, crop, split, and prepare it for accurate Fixed Layout conversion.

Key Preprocessing Highlights

  • Automatic detection and removal of print crop & registration marks.
  • Cropping pages precisely to final trim box dimensions.
  • Splitting spread pages into individual pages while maintaining exact aspect ratios.

Structural Operations

  • Automatic EPUB bookmark & Table of Contents generation.
  • Logical page label assignment matching print pagination.
  • Preserving and validating internal document hyperlinks.

Intelligent PDF Separation

Unlike conventional workflows, we separate the source PDF into two optimized operational streams to extract content with absolute accuracy.

Image-Only PDF Stream

The visual layer is extracted by removing all text elements while isolating high-resolution graphics, illustrations, and background layers. This produces page-perfect image assets complying with Apple Books and IDPF standards.

Text-Only PDF Stream

A secondary version retains text data. Our engine extracts embedded fonts, font characteristics, text colors, character positions, exact coordinates, and reading order directly from the raw PDF binary.

Image & Asset Optimization

Our image extraction engine identifies and exports each page image at the optimal resolution while maintaining platform compliance and small file footprints.

High Visual Fidelity

Matching original print resolution while using advanced WebP/PNG compression to minimize eBook download times.

Aspect Ratio Scaling

Accurate page dimension calculations matching print layout ratios and validated across e-readers and tablets.

Automated FXL Generation

Processed assets—including page images, extracted fonts, text coordinates, colors, and structural metadata—are compiled by our engine to build a production-ready Fixed Layout EPUB.

  • Recreates original page layout with precise positioning of every text element.
  • Preserves typographic styles, font properties, baseline alignments, and text flow.
  • Retains exact appearance, margins, and look-and-feel of the printed publication.
