What Gets Stripped

  • ✓Hidden control characters (zero-width spaces, etc.)
  • ✓Weird Unicode formatting characters
  • ✓Excessive whitespace and tabs
  • ✓HTML tags and entities
  • ✓PDF extraction artifacts
  • ✓Copy-paste formatting residue

How to Clean Messy Text

  1. Paste messy text - From PDF, Word, Slack, email, or web
  2. Select cleaning level - Light (basic), Medium (remove formatting), Nuclear (plain ASCII)
  3. Choose output format - Plain text or Markdown
  4. Copy cleaned text - Ready for documentation, code, or terminal

The Hidden Characters Problem

Rich text contains invisible Unicode: PDFs and Word docs embed formatting as control characters, zero-width spaces (U+200B), non-breaking spaces ( ), and smart quotes (“”). When pasted into code or terminals, these break parsing. This tool uses regex patterns: /[​-‍]/g to strip them.

Line break chaos: Different systems use different line endings - Windows (), Unix (), old Mac (). PDFs often insert hard line breaks mid-sentence for layout. This tool normalizes line endings and removes orphaned breaks while preserving paragraph structure.

Pro tip: Use 'Medium' cleaning for most tasks - it removes formatting but preserves structure. Use 'Nuclear' when pasting into strict environments (cron jobs, config files, shell scripts) where any hidden character breaks execution. For Markdown conversion, works great for copying web articles into documentation.
