Will my STP file be deleted after conversion?

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

What cad 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.

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

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

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.

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.
