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 KEY over other formats?

Keynote Presentation offers stunning animations and presentation design on Apple devices. It's widely used for Apple users for presentations, pitches and visual storytelling, making it an excellent choice for most document needs.

Will my MBX file be deleted after conversion?

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

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

What if my MBX 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.
