Will my HDR file be deleted after conversion?

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

What image quality settings should I use?

For photos, use the High quality preset. For web graphics, Medium offers a good size-quality balance. The default preset works well for most use cases.

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 HDR file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new MPEG copy is created.
