Smart quote converter

Convert between straight " quotes and curly “ typographic quotes ” — apostrophes handled by context.

Text stays in this browser — nothing is sent anywhere.

Straight→curly uses opening/closing context heuristics (apostrophes inside words like don't stay as the closing form, which is correct for English). Curly→straight is exact. Converted code or measurements ('5", 3') may come out curly — check code snippets by eye.

How to use

  1. Paste the text.
  2. Choose straight→curly or curly→straight.
  3. Copy the converted text.
