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 IGS file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new STP 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.

Yes. There are no restrictions on how you use your converted files. Convert IGS to STP for personal, educational, or commercial projects freely.

Yes! Xonvert supports reverse conversion too. Visit the STP to IGS converter page to convert back.

Transparency is a concept specific to image formats. For cad files, all content data is preserved during conversion.
