字符串与文本 — About These Tools

Text utilities transform and analyze strings: change case, count words and characters, remove duplicates, sort lines, escape and unescape. Paste your text, apply a transform, copy the result — the text never leaves your device.

常见问题

Is my text uploaded anywhere?

No. All transforms run in your browser with JavaScript. Your text never leaves your device, which makes these tools safe for confidential drafts.

Is there a length limit?

The practical limit is your device’s memory — texts of several megabytes transform instantly. Very large inputs may slow older browsers.

Do the tools preserve Unicode and emoji?

Yes. Transforms operate on Unicode code points, so emoji, CJK characters, and accented letters round-trip correctly.
