About URL Encoder / Decoder

Encode special characters in URLs for safe transmission and decode percent-encoded strings back to readable text. Supports full URL encoding, query parameter encoding, and component-level encoding.

Frequently Asked Questions

URL encoding replaces unsafe ASCII characters with a % followed by two hexadecimal digits. For example, a space becomes %20 or +.

Use encodeURIComponent for individual query parameter values — it encodes all special characters. Use encodeURI for a full URL — it preserves characters like / and : that have meaning in URLs.

No. All encoding and decoding happens locally in your browser. Nothing is sent to any server.

Currently the tool processes one URL or string at a time for clarity. Paste the next one to decode it instantly.
