Text Cleaner
Paste text and clean it up with four toggleable cleaning operations: collapse multiple spaces into one, convert smart (curly) quotes to straight quotes, strip non-ASCII characters, and remove control characters. All four are enabled by default — toggle any off to keep that aspect of the text unchanged.
Smart-to-straight quote conversion handles both single and double curly quotes, which is essential when pasting from Word, Google Docs, or macOS which silently replace straight quotes. Non-ASCII removal strips accented characters, symbols, and other non-ASCII codepoints. Control character removal strips invisible characters like null bytes, backspaces, and form feeds that can cause issues in code and data files.
Everything runs in your browser — your text is never sent anywhere.

Frequently asked questions
What are 'smart quotes'?▼
Smart quotes (also called curly quotes or typographer's quotes) are the left- and right-facing quotation marks like “ ” and ‘ ’, as opposed to the straight neutral marks " and '. Word processors and macOS auto-convert straight quotes to smart quotes, which can break code, CSV files, and data processing.
Will removing non-ASCII characters strip accented letters?▼
Yes — characters like é, ñ, ü, and ç are outside the ASCII range and will be removed when that option is enabled. If you need to keep accented characters, toggle that option off.
What are control characters?▼
Control characters are invisible characters in the 0x00–0x1F and 0x7F–0x9F ranges — null bytes, backspaces, escape sequences, form feeds, and similar. They occasionally appear in text copied from terminals, binary files, or corrupted data and can cause subtle bugs.
