01 / Overview

What does a smart quotes converter do?

A smart quotes converter changes curly quotation marks into plain straight quotes, or turns straight quotes into typographic opening and closing marks. Paste text, choose the direction and copy the live result. The conversion runs in your browser, so drafts, code and document excerpts are not uploaded.

Who it's for

  • Developers removing curly marks that can break JSON, code strings, command examples or exact text comparisons.
  • Editors and publishers typesetting straight keyboard quotes before a draft moves into a CMS or page layout.
  • Writers standardizing apostrophes and quotation marks after combining text from Word, email, notes and web pages.
  • Data teams cleaning pasted CSV fields and exports while leaving the rest of each value untouched.

Curly quotes look polished in articles, books and marketing copy, while straight ASCII quotes are safer in source code, JSON, CSV and plain-text systems. This converter handles both jobs without changing your words, spacing or line breaks. Choose all quotes or limit the pass to double or single marks when a document mixes styles on purpose.

The straight-to-smart mode uses nearby letters, spaces and punctuation to choose opening and closing marks. Apostrophes inside contractions and possessives become closing single marks, while common shortened forms such as '90s receive an apostrophe instead of an opening quote.

FAQ

Is my text uploaded anywhere?

No. Quote conversion happens locally with JavaScript in your browser. The pasted text is not sent to a server, so you can use the tool for unpublished drafts, internal notes, code samples and other text you would rather keep on your device.

Is the smart quotes converter free?

Yes. The converter is free to use without an account, download or usage limit. Paste your text, select a direction and copy the result. There is no paid conversion step and no sign-up gate.

How much text can I convert at once?

There is no fixed character limit. Conversion is a lightweight pass through the text and works well for long articles or document excerpts. The practical limit depends on your browser memory and how much text remains comfortable to review in one editor.

What is the difference between smart quotes and straight quotes?

Smart quotes are directional Unicode characters with distinct opening and closing forms. Straight quotes are the plain ASCII characters available on a keyboard. Smart quotes suit polished prose, while straight quotes are often required by programming languages, JSON, CSV and older plain-text systems.

Can it convert straight quotes to curly quotes?

Yes. Select Straight to smart and the tool uses surrounding spaces, letters and punctuation to choose opening or closing curly marks. It also recognizes apostrophes inside contractions, possessives and common shortened forms such as '90s.

Will smart quotes break JSON or code?

They can. JSON and most programming languages require straight ASCII quotation marks as string delimiters. A curly mark that looks similar can cause a parser or compiler error. Convert code-like text to straight quotes, then review the result before running it.

Does it change apostrophes inside words?

Yes, when single quotes are included. Smart-to-straight mode changes curly apostrophes to ASCII apostrophes. Straight-to-smart mode changes marks inside words into typographic apostrophes, so contractions such as don't and possessives such as Sam's keep their meaning.

Does it change foot and inch marks?

Dedicated Unicode prime and double-prime symbols are preserved. The converter also keeps an unpaired straight mark after a number when it looks like a measurement. If a document uses quotation marks as approximate measurement symbols inside dialogue, review that uncommon case manually.
