Frequently asked questions

What happens to the data I paste in?
It's processed in your browser and never uploaded. Refreshing the page clears it.
Can I use this on sensitive or private data?
Because nothing leaves your browser, these tools are a reasonable choice for sensitive data — though we'd still recommend not pasting real secrets like production passwords into any web page.
