What is URL Encoding/Decoding?
URL encoding, also known as percent encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. URL encoding is used when placing text in a query string to convert characters that are not allowed in URLs to a format that is acceptable. For example, spaces are not allowed in URLs, so they are replaced with %20 or + in URL encoding.
Features of Our URL Encoder/Decoder
Our browser-based URL encoder/decoder offers several useful features:
- Bidirectional Conversion - Encode URLs to make them safe for transmission and decode encoded URLs back to their original form
- Component Encoding - Option to use encodeURIComponent for stricter encoding of URL components
- Special Character Handling - Properly handle spaces, international characters, and symbols in URLs
- Copy Functionality - Easily copy the encoded or decoded URL to your clipboard
- URL Parsing - View the different components of a URL (protocol, domain, path, query parameters)
How to Use the URL Encoder/Decoder
Using our URL encoder/decoder is straightforward:
- Enter or paste your URL or text in the input field
- Select the operation (Encode or Decode)
- Choose the encoding method if encoding (URI or URI Component)
- Click the "Encode" or "Decode" button
- The result will appear in the output field
- Click the "Copy" button to copy the result to your clipboard
Benefits of Using Our URL Encoder/Decoder
There are several advantages to using our online URL encoder/decoder:
- Privacy-Focused - All processing happens in your browser; no data is sent to our servers
- Accurate Conversion - Properly handle all special characters and encoding rules
- Time-Saving - Quickly encode or decode URLs without manual conversion
- Free to Use - No registration or payment required
- Works Offline - Once loaded, the tool can work without an internet connection
Common Use Cases for URL Encoding/Decoding
URL encoding/decoding is essential in many scenarios:
- Web Development - Create properly formatted URLs for links and form submissions
- API Integration - Ensure parameters are correctly encoded for API requests
- Data Transmission - Safely transmit data containing special characters in URLs
- Debugging - Decode encoded URLs to understand their components
- Internationalization - Handle non-ASCII characters in URLs
URL Encoding Rules
URL encoding follows specific rules:
- Alphanumeric characters (A-Z, a-z, 0-9) and certain special characters (-_.~) remain unchanged
- Spaces can be encoded as %20 or + (plus sign)
- All other characters are encoded as %XX, where XX is the hexadecimal ASCII value of the character
- Reserved characters like ?, &, =, /, :, and # must be encoded when used in certain parts of a URL
- International characters are first converted to their UTF-8 bytes and then each byte is percent-encoded
Difference Between encodeURI and encodeURIComponent
There are two main JavaScript functions for URL encoding, each with a specific purpose:
- encodeURI - Used to encode a complete URL. It doesn't encode characters that are part of the URL syntax, like /, ?, :, @, &, =, +, $, and #.
- encodeURIComponent - Used to encode a component of a URL, such as a query parameter. It encodes all characters that could interfere with URL parsing, including /, ?, :, @, &, =, +, $, and #.
Technical Details
Our URL encoder/decoder uses JavaScript's built-in encodeURI, encodeURIComponent, decodeURI, and decodeURIComponent functions to ensure accurate and standards-compliant encoding and decoding. The tool handles edge cases and provides options for different encoding needs.
Privacy and Security
We take your privacy seriously. This URL encoder/decoder processes all data locally in your browser. Your URLs and text are never sent to our servers or stored anywhere. You can even use this tool offline once the page has loaded.
Conclusion
Our URL encoder/decoder is an essential tool for web developers, API integrators, and anyone who works with URLs. By providing easy conversion between regular text and URL-encoded format, it helps ensure that your URLs are properly formatted for safe transmission over the internet.
