Remove blank lines. Remove empty or whitespace-only lines from text in your browser while preserving the content and indentation of every nonblank line. Paste text into the input box to remove blank lines immediately.

By default, the tool treats lines containing only spaces or tabs as blank. It preserves the text, leading spaces, and trailing spaces on every nonblank line, which is useful when cleaning code, logs, copied spreadsheet values, or draft documents.

Turn off Trim spaces and tabs from blank lines if you want to remove only completely empty lines and keep whitespace-only lines. Processing happens locally in your browser.

For other cleanup tasks, use Duplicate line remover, Find and replace, or Text statistics.

How to use this online tool

Remove blank lines is designed for fast browser workflows when you need to format, validate, convert, decode, encode, generate, or inspect data without opening a heavy desktop app. Start with the input field or visible options, review the result, then copy or download the output for the next step.

Private processing in your browser

Remove blank lines keeps the normal processing step local in your browser. That is useful for code snippets, tokens, documents, configuration values, text samples, and other material that should not be sent to a remote service unless you explicitly choose to share it.

When this tool is useful

Use Remove blank lines for repeatable developer tasks, technical documentation, QA checks, quick conversions, debugging, content cleanup, and internal team workflows. The page focuses on clear inputs, immediate feedback, and output that is easy to reuse in code, reports, tickets, emails, or notes.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
