Frequently Asked Questions

Can I convert back to the original format?

Yes, for data content. Format-specific metadata may not survive a round-trip conversion.

Is my input collected for analytics?

No — client-side tools don't transmit your input. Standard page-view analytics may run, but your data is never included.

Does this work offline?

After the initial page load, yes — all processing is local. You need connectivity to load the page itself.

Is my data saved after I close the tab?

No. Client-side tools don't persist input. Once you close or navigate away, your data is gone.
