Is Xonvert open source?

Xonvert uses open-source conversion libraries (FFmpeg, libvips, etc.) compiled to WebAssembly. The conversion engine is transparent and trustworthy.

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 CBZ to MOBI 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 MOBI over CBZ?

Mobipocket eBook offers legacy Kindle device backward compatibility, while Comic Book ZIP is known for simple image archive format for reading sequential art. 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.
