Is there an API for SUB to SBV 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 SBV 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 SUB files?

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

Can I convert multiple SUB 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 SBV over other formats?

SBV Subtitle offers simple format easily editable in any text editor. It's widely used for YouTube video captioning and simple subtitle creation, making it an excellent choice for most subtitle needs.
