FAQ

Is this online text converter private?

Yes. The conversions run locally in your browser, and the tool JavaScript does not send your text to a server.

What does “Collapse whitespace” do?

It reduces runs of spaces/tabs (and optionally other whitespace) to a single space; with “Keep line breaks” enabled, it cleans each line without merging lines.

Why does URL decode sometimes fail?

URL decode fails when the input contains invalid percent-encoding (for example, “%ZZ”). Fix the encoding or decode a smaller portion.

Does Base64 encode/decode support Unicode?

Yes. The Base64 tools treat text as UTF-8 so non-ASCII characters can be encoded and restored correctly.

How do I remove duplicate lines from a list?

Choose “Unique lines (keep order)”, paste your list (one item per line), and convert.

Can I convert Windows line endings to Unix (LF)?

Yes. Use “Convert line endings to LF” to normalize CRLF/CR into LF.

What’s the difference between HTML escape and HTML unescape?

HTML escape turns characters like < into entities like &lt;; HTML unescape converts entities back into normal characters.
