Is it safe to convert my XLS files here?

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

Is there an API for XLS to AZW conversion?

Xonvert is a browser-based tool without a server API, since all processing happens client-side. For automated conversion, you can use Xonvert's PRO features or integrate the underlying open-source libraries directly.

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 AZW 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 XLS files?

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

Can I convert multiple XLS 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.
