decodeURIComponentHow to use this URL Encoder & Decoder
Enter your text or URL
Paste plain text into the Encode panel, or a percent-encoded string into the Decode panel. Works with query values, full paths, and Unicode text.
Encode or decode
Use the corresponding button to transform your input. Invalid percent sequences show a clear error instead of garbled output.
Copy or swap
Copy the result, or use Swap to move output back into the input and chain another pass.
Why this URL encoder helps
Accurate percent encoding
Uses browser-native encodeURIComponent and decodeURIComponent for RFC-compliant encoding — no server round trip.
Live preview as you type
Output updates in real time so you can iterate on query strings and path segments without pressing a button between edits.
Error handling for malformed URIs
When a percent-encoded string contains an invalid sequence, the tool shows a readable error instead of broken output.
Swap and chain operations
Move output back to input so you can run multiple encode–decode cycles without switching panels.
