Add Line Numbers

Add or remove line numbers from any text

Line numbers are indispensable when reviewing code, sharing log snippets, or documenting step-by-step instructions. Adding line numbers makes it easy to reference specific lines in conversations or bug reports. The remove mode strips existing numbering — useful when you copy numbered content from a document or terminal and need the raw text back for further processing.
