A Complete Guide to using URL Encoder / Decoder
Encode or decode URL components for safe transmission in web requests.
What exactly is the URL Encoder / Decoder?
The URL Encoder/Decoder converts text to percent-encoded format (for safe use in URLs) and decodes percent-encoded strings back to readable text. URL encoding is critical whenever you need to include special characters, spaces, or non-ASCII characters in web addresses and query parameters.
The tool uses JavaScript's encodeURIComponent() for encoding, which is the gold standard for encoding individual URL components. It handles all special characters including spaces (%20), ampersands (%26), and Unicode characters.
How to Use This Tool
Encode or decode URLs instantly:
- Select 'Encode' or 'Decode' mode.

- Click the button to see the result.
- Copy the output for use in your code or browser.
Common Developer Use Cases
URL encoding is foundational to web development:
- Query Parameters: Encode values before appending them to URL query strings to prevent breaking the URL structure.
- API Requests: Ensure special characters in request parameters are properly escaped.
- Form Data: Encode form values for application/x-www-form-urlencoded content type submissions.
- Debugging: Decode URLs to inspect human-readable query parameter values.
