Online Text Cleaner for empty lines, edge trimming, and trailing whitespace

• Remove all empty lines

  Deletes every blank line in the text. Useful when you want to compact log output, reformat pasted content, or strip unnecessary vertical space.

• Collapse consecutive empty lines

  Replaces multiple blank lines with a single one. Keeps paragraph separation intact while removing excessive spacing.

• Trim leading and trailing empty lines

  Removes empty lines only at the beginning and end of the text. Interior spacing stays exactly as written.

• Per-line trimming

  Strips leading and trailing whitespace from every line before the empty-line mode is applied. Helps normalize irregular indentation.

• Trailing space removal

  Removes spaces and tabs at the end of each line. Useful before committing code or preparing text for strict formatters.

• Instant preview

  Input and output stay side by side, and the result refreshes as soon as the mode or options change.

1. 1

   Paste your text into the input area.

2. 2

   Choose a cleaning mode: remove all empty lines, collapse consecutive ones, or trim only the edges.

3. 3

   Toggle additional options if you need per-line trimming, trailing space removal, or line ending preservation.

4. 4

   Compare input and output to confirm paragraph spacing, indentation, and trailing whitespace are correct.

5. 5

   Copy the result to your clipboard or download it as a .txt file.

• Use Remove All when you want the most compact output, such as after pasting from a rich text source with many blank lines.
• Use Collapse when you need to reduce spacing while keeping paragraph structure visible.
• Use Trim Edges when the excess whitespace is only at the top or bottom of the text, such as after copying from a code block with leading blank lines.
• Turn on Trim Each Line if the lines have inconsistent indentation or leading/trailing spaces that you want to normalize.
• Turn on Remove Trailing Spaces if you are preparing text for a linter, a code review, or a system that rejects trailing whitespace.

After cleaning the source text, use Text Replace when you still need to rewrite repeated terms, field names, or fixed patterns. If variable names, headings, or list labels need consistent casing, continue with Case Converter ; before publishing or submitting the result, Text Counter helps check character and byte limits. For line-based lists, logs, config entries, dedupe, and sorting, Line Tools is the better follow-up tool. If the cleaned text is a JSON payload, open JSON Formatter next to validate and inspect the structure; if it is table-like data, CSV Tools can preview columns and export a cleaner result.

• Use Collapse mode instead of Remove All when the original paragraph structure matters and you only want to reduce excessive spacing.
• Turn on Trim Each Line if the input has irregular indentation that would interfere with the empty-line detection.
• Enable Preserve Line Endings if the output will be used in a system that requires a specific line break style, such as Windows \r\n.
• Lines containing only spaces or tabs are treated as empty. If you need to keep whitespace-only lines, disable the per-line whitespace detection.
• Download the result as .txt after processing to keep the cleaned version without relying on copy-paste.

• Very large texts (over 10,000 lines) may cause brief rendering pauses while the result is regenerated.
• Lines containing only whitespace characters such as spaces and tabs are considered empty. There is no option to treat them as non-empty in the current version.
• The Preserve Line Endings option detects whether the input uses \n or \r\n globally. Mixed line ending styles in the same text are normalized to the detected style.
• This tool does not modify the visible content of non-empty lines beyond the optional per-line trimming.
• All processing happens locally in the browser. Nothing is uploaded to a server.
