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 DFXP over ASS?

DFXP Subtitle offers used by Netflix and other streaming services, while ASS Subtitle is known for advanced styling: fonts, colors, positioning, karaoke and animation. 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 ASS files here?

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

Is there an API for ASS to DFXP 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.
