Frequently Asked Questions
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 HTML over other formats?▼
HTML Document offers universal web standard rendered by every browser on every device. It's widely used for web pages, web applications, email templates and online documents, making it an excellent choice for most document needs.
Will my PSB file be deleted after conversion?▼
No. Your original PSB file is never modified or deleted. Xonvert creates a separate HTML 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 PSB file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new HTML copy is created.
What if my PSB 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.
