Free Online Text Cleaner & Find and Replace — Strip Empty Lines & Spaces

Clean Text, Collapse Extra Spaces & Find/Replace Fast. Batch find & replace, strip empty lines, normalize whitespace, and sanitize text instantly.

What is Text Cleaner and what does it do?

The Text Cleaner & Whitespace Normalizer is a comprehensive text formatting tool that strips unwanted formatting, normalizes irregular spacing, and purifies text copied from PDFs, websites, and emails.

With configurable cleanup rules for trailing spaces, redundant empty lines, non-breaking spaces, and smart quotes, it eliminates formatting artifacts in seconds without sending your drafts to remote servers.

  • Remove trailing whitespace, collapse multiple consecutive spaces into single spaces, and strip leading spaces.
  • Remove blank lines, collapse consecutive empty lines, or trim all whitespace across the entire document.
  • Convert smart/curly quotes (“ ” ‘ ’) and em-dashes into standardized ASCII quotes and hyphens.
  • Strip HTML/XML tags and non-printable control characters from copied clipboard text.
  • Instant before-and-after statistics comparing character count, word count, line count, and saved bytes.

How does Text Cleaner work?

The text is processed through a sequential pipeline of regular expressions corresponding to the enabled cleaning rules.

String transformations occur in memory, stripping matched control characters, normalizing whitespace sequences, and returning clean text with zero network overhead.

100% private: all processing happens locally in your browser using client-side WebAssembly, HTML5 Canvas, and modern Web APIs. Your files are never uploaded to any server.
