Special Notes

EPUB Files

Image-Based Comics Only

Password Protection

ComicVerse does not support password-protected or encrypted archives. Remove password protection before importing.

Common Issues

:::details File won't import

"Unsupported format" error

  • Verify file extension is one of the supported types
  • Check that the file isn't corrupted
  • Make sure archive contains image files, not documents

"Password protected" error

  • Remove password protection using archive software on your computer
  • Re-compress the files without a password

:::

:::details Pages appear out of order

Images inside archives should be named sequentially:

  • Good: 001.jpg, 002.jpg, 003.jpg
  • Bad: 1.jpg, 02.jpg, 003.jpg

If pages are out of order, extract and re-compress with properly numbered files.

:::

:::details Large files are slow

For files over 200MB:

  • Consider using OPDS servers to stream instead of importing locally
  • Or convert to CB7 format for better compression
