URL Decoder

Decode URL-encoded text with multiple decoding modes. Auto-detect mode handles both %20 and + as spaces. Form data mode specifically converts + to spaces for application/x-www-form-urlencoded format. Standard mode only decodes percent-encoded sequences. Real-time decoding as you type with character count display. Includes reference guide showing common URL encodings (%20→space, %21→!, %23→#, %26→&, %2F→/, %3F→?, %3D→=, %40→@). Copy decoded text or paste from clipboard. Perfect for debugging URL parameters, reading encoded query strings, and understanding API responses. Works entirely in browser for privacy and speed.
