Overview

EPUB files are common in publishing and e-books, but they are not natively supported for upload into GoldFynch. If you have documents in EPUB format that need to be reviewed or produced in GoldFynch, converting them to PDF before upload is the most reliable and efficient solution.


Short version: EPUBs are great for Kindles. PDFs are great for eDiscovery.


Why EPUB Files Do Not Upload Cleanly

EPUB files are reflowable documents designed to adjust dynamically based on screen size and reader settings. That flexibility is exactly what makes them problematic for legal review platforms.


Common issues with EPUB files include:

  • No fixed page layout

  • Inconsistent formatting across viewers

  • Limited or nonstandard metadata

  • Difficulty preserving a stable review and production format


GoldFynch relies on a consistent file structure to support review tools, search, and production workflows. EPUB simply does not meet those requirements.


Recommended Solution: Convert EPUB to PDF

Converting your EPUB file to PDF creates a fixed, review-ready document that uploads and processes smoothly in GoldFynch.


Benefits of converting to PDF:

  • Preserves a consistent layout and pagination

  • Fully compatible with GoldFynch review and production tools

  • Searchable text when converted properly

  • Predictable behavior during export and production

This approach avoids processing errors and saves time during review. No surprises. No mystery formatting.


How to Convert an EPUB File to PDF

There are several online conversion tools that you can use to convert EPUB files before uploading.

  • Web-based EPUB to PDF converters - PDF Converter EPUB to PDF - Convert eBooks to PDF 

  • These are best for smaller files. You may run into some formatting issues with larger files


After Conversion: Uploading to GoldFynch

Once converted:

  1. Confirm the PDF opens correctly and displays as expected

  2. Verify the text is searchable if OCR or text extraction is needed

  3. Upload the PDF into your GoldFynch case as you would any other document

From there, the file can be reviewed, searched, tagged, and produced like any standard PDF.
