Frequently asked questions
- What is the difference between LF and CRLF line endings?
- LF (\n) is used on Unix, macOS and Linux, while CRLF (\r\n) is used on Windows. Mixed endings can cause noisy diffs, so normalising them is useful.
- How is this different from the basic Text Cleaner?
- The basic Text Cleaner covers everyday tidy-ups: trim lines, collapse spaces and remove blank lines. This advanced version adds developer options like tabs and spaces conversion, line-ending normalisation and indentation removal.
- Is my text uploaded anywhere?
- No. Cleaning happens entirely in your browser, so your text never leaves your device.
