Frequently Asked Questions
Is my text sent to a server?

Does this work on mobile?
Yes, the tool works in any modern browser, including on phones and tablets.
Can I undo the result?
The transformation doesn't modify your original input - it's still there in the input box, so you can edit it or start over at any time.
Can I save the result?
Yes, use the Download button to save the result as a plain text file, or Copy to paste it directly wherever you need it.
