Are my files uploaded to a server?

No. Zero files are transmitted anywhere. Xonvert processes everything using client-side JavaScript and WebAssembly. Your files stay on your machine.

Can I preview the FB2 output before downloading?

Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.

Can I convert password-protected CBZ files?

Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.

Can I convert multiple CBZ files at once?

Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.

What's the maximum number of files I can convert at once?

Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.

Why choose FB2 over other formats?

FictionBook offers clean XML structure, rich semantic markup for fiction. It's widely used for Russian ebook market, fan translations and libre ebook distribution, making it an excellent choice for most ebook needs.

Will my CBZ file be deleted after conversion?

No. Your original CBZ file is never modified or deleted. Xonvert creates a separate FB2 copy — your source file remains untouched.
