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 FB2 over other formats?

FictionBook offers clean XML structure, rich semantic markup for fiction. It's widely used for Russian ebook market, fan translations and libre ebook distribution, making it an excellent choice for most ebook needs.

Will my NUMBERS file be deleted after conversion?

No. Your original NUMBERS file is never modified or deleted. Xonvert creates a separate FB2 copy — your source file remains untouched.

What document 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 NUMBERS file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new FB2 copy is created.

What if my NUMBERS 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.
