Lowercase Converter

The Lowercase Converter quietly turns any text into small letters the moment you paste it. It is the fastest fix for a paragraph typed with Caps Lock stuck on, and a reliable way to normalize email addresses, URLs, tags and usernames that must match exactly. What you paste is what gets converted — nothing is sent anywhere.

How to use Lowercase Converter

  1. Type or paste your text into the box.
  2. The lowercase version appears in the result box immediately.
  3. Copy the result or download it as a .txt file.

Supported behavior

  • Every letter A–Z becomes a–z, including accented letters such as É → é.
  • Numbers, punctuation and line breaks are untouched.
  • The German ß and similar special letters follow your browser's Unicode rules.

Best for

  • Repairing text typed with Caps Lock on.
  • Normalizing email addresses and URLs before saving them.
  • Standardizing tags, usernames and file names.

Limits

  • Lowercasing is destructive: sentence capitals and proper nouns are lost and cannot be restored automatically.
  • Some languages have special casing rules (for example Turkish i) that follow your browser's default Unicode mapping, not locale-specific rules.

Privacy notes

  • Processing happens entirely in your browser, so nothing you paste here is sent anywhere.
  • The tool keeps no history of what you convert.

Does it change numbers or punctuation?

No. Only letters change; everything else is copied through exactly.

Is there a character limit?

There is no set limit — the practical ceiling is your device's memory, and ordinary documents convert instantly.
