Can I use Xonvert offline?

Yes! Once the converter page has loaded, it works without an internet connection. All conversion logic runs locally in your browser.

Does CB7 to CBZ conversion work on slow internet?

Yes — and even with no internet at all. Once the page loads, conversion is entirely offline. Speed depends on your device's CPU, not your internet connection.

How is Xonvert different from other online converters?

Most online converters upload your files to their servers. Xonvert processes everything locally in your browser — your files never leave your device. It's faster, more private, and works offline.

Is there a file size limit?

There is no strict file size limit. However, very large files (over 500MB) may be limited by your device's available memory.

What are the advantages of CBZ over CB7?

Comic Book ZIP offers simple image archive format for reading sequential art, while CB7 Comic Book is known for best compression ratio of all comic book archive formats. The best choice depends on your specific needs — compatibility, quality, or file size.

How does Xonvert compare to desktop software?

Xonvert offers comparable quality to desktop converters with the convenience of browser-based access. No installation, no updates, instant availability.

Is it safe to convert my CB7 files here?

Absolutely. Your files never leave your device — all processing happens in your browser using WebAssembly technology.
