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 <; HTML unescape converts entities back into normal characters.
