Why can't I upload my epub/ebook file?

Learn how to troubleshoot error when uploading EPUB files to Logically.app. Includes tips for large files and format verification.

Updated over 2 weeks ago

EPUB (Electronic Publication) is a popular e-book file format. While Logically.app aims to support a wide range of file types, there are some limitations and best practices to keep in mind when uploading EPUB files. This article will guide you through the process and offer solutions for common issues.

Important Notes

  • Not all EPUB files may be compatible with Logically.app, especially if they have non-standard structures or content.

  • Large EPUB files (over 100MB) may face upload restrictions.

  • If you continue to face issues, reach out to our support with specific details about your file and the problem you're encountering.

Troubleshooting EPUB Uploads

If you encounter issues uploading your EPUB file, try the following steps:

1. Verify File Format

Ensure your file is a genuine EPUB file. Some e-books might appear as EPUB files but are actually folders or other formats. To check:

  • On Windows, try changing the file extension from .epub to .zip and see if you can open it as an archive.

  • On Mac, right-click the file and select "Show Package Contents" to see if it reveals a folder structure.

2. Compress and Rename

If your EPUB file is actually a folder (which can happen on some systems), try this workaround:

  1. Compress the folder into a ZIP file.

  2. Rename the resulting .zip file to end with .epub instead.

  3. Try uploading this modified file.

3. Convert to PDF

If all else fails, consider converting your EPUB to PDF format, which is widely supported by Logically.app:

  1. Use an online converter or software like Calibre to convert your EPUB to PDF.

  2. Upload the resulting PDF file.
