Images Inside Archives
Comic archives can contain pages in JPG/JPEG, PNG, GIF, and WebP. BMP and TIFF pages are additionally supported in CBR and CBT archives.
Recommendations
CBZ is the safest all-round choice. It's the fastest to open and universally compatible. CB7 gives the smallest files if storage is tight, at a small cost in opening speed. PDF works well for official digital releases.
Special Notes
EPUB Files
ComicVerse supports image-based comic EPUBs. Text-centric ebooks aren't supported. For novels, use a dedicated ebook reader.
Password Protection
Password-protected or encrypted archives can't be opened. Remove the password on a computer and re-compress before importing.
Common Issues
File won't import
- Verify the extension is one of the supported types above
- Check the file opens correctly on a computer (it may be corrupted)
- Make sure the archive contains image files, not documents
- Remove password protection if present
Pages appear out of order
Pages inside archives are read in filename order, so they should be numbered with equal digits.
- Good:
001.jpg,002.jpg,003.jpg - Bad:
1.jpg,02.jpg,003.jpg
Extract and re-compress with padded numbering to fix the order.
Very large files are slow
For huge files (200 MB and up), consider streaming from an OPDS server instead of importing, or convert to CB7 for better compression.
