Frequently Asked Questions

Common questions about the free online smart quote converter.

Smart or curly quotes are typographic marks that lean in the direction of the text, opening at the start of a quotation and closing at the end.
A quote is treated as opening at the start of the text, after whitespace or after a bracket, and as closing in every other position.
In curly mode, a mark between two letters becomes a curly apostrophe, so contractions and possessives such as don't and it's look right.
Yes. Choose Curly to straight and every curly single or double mark, including German and French pairs, becomes a plain straight quote.
It flips the direction of the quotes already in your text, which is handy when text pasted from another source points the wrong way.
Be careful with code. Straight quotes matter in programming languages, so keep them straight or convert the document back before you run it.
No. All quote conversion happens locally in your browser, so your text never leaves your device.
