URL Encoder & Decoder

Encode and decode URL text with multiple encoding modes. Standard mode (encodeURIComponent) encodes all special characters except alphanumerics and - _ . ! ~ * ' ( ).

Includes character encoding reference showing common character conversions (space → %20, # → %23, & → %26, etc.). Real-time encoding as you type with character count display. Decode encoded URLs back to readable text with one click. Copy encoded text or paste from clipboard. Perfect for URL parameters, query strings, API requests, and form data encoding.
