Will my DFXP file be deleted after conversion?

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

What subtitle quality settings should I use?

Default settings are optimized for the best balance of quality and file size. Adjust only if you have specific requirements.

Does this work on my phone or tablet?

Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.

Can I undo a conversion?

Since your original DFXP file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new TTML copy is created.

What if my DFXP file won't convert?

Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.

How many times can I convert DFXP to TTML per day?

There's no daily limit for free users. Convert as many files as you need, as often as you need. PRO users get additional batch processing features.

Can I use this converter for commercial purposes?

Yes. There are no restrictions on how you use your converted files. Convert DFXP to TTML for personal, educational, or commercial projects freely.
