What Is Smart Quotes Converter?

The Smart Quotes Converter transforms straight quotation marks into typographically correct curly (smart) quotes, or converts smart quotes back to straight quotes. In the to-smart direction, it also converts three consecutive periods into an ellipsis character (…) and double hyphens into an em dash (—). Smart quotes are the standard in professional publishing, while straight quotes are needed for code and plain-text formats. The tool correctly pairs opening and closing quotation marks for both double and single quotes.

Technical Guide

The converter uses regex pattern matching to identify quote characters and their context. For straight-to-smart conversion, it first handles quoted strings (matching pairs), then uses lookbehind assertions to determine whether a remaining quote should be an opening or closing mark based on its position relative to whitespace or line boundaries. Double quotes become U+201C (left double quotation mark) and U+201D (right double quotation mark). Single quotes become U+2018 (left single quotation mark) and U+2019 (right single quotation mark). The reverse direction maps all Unicode quotation mark variants back to ASCII straight quotes. Additional typography conversions include triple periods to ellipsis (U+2026) and double hyphens to em dash (U+2014).

Frequently Asked Questions

QWhat are smart quotes?
Smart (curly) quotes are typographically correct quotation marks that curve toward the quoted text: “ ” for double and ‘ ’ for single quotes.
QWhy would I want straight quotes?
Straight quotes are required in programming languages, and some plain-text systems do not support Unicode smart quotes.
QDoes it handle apostrophes?
Yes, apostrophes within words are converted to right single quotation marks (’) in smart mode.
QWhat other characters are converted?
In smart mode, ... becomes … (ellipsis) and -- becomes — (em dash). In straight mode, these are reversed.
