URL Encoder / Decoder
Safely encode and decode URLs and URI components instantly using a fast browser-based tool.
Features
- URL Encoding: Safely encode text strings or complete URLs so they can be transmitted over the internet without data loss or corruption.
- URL Decoding: Reverse the URL encoding process to read the original text or URL.
- Component vs Full URI: Support for both standard full URI encoding and component-level encoding.
- Browser-Based Processing: Your data never leaves your device. This tool runs 100% locally.
- Developer Friendly: Includes 1-click copy and download functionality, perfect for integrating with your workflows.
How it works
URL encoding (also known as Percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Certain characters, such as spaces or special symbols, must be encoded to be safely transmitted.
Simply select your desired operation using the tabs above. Type or paste your input into the left panel, and the URL Encoder/Decoder will automatically generate the corresponding output in the right panel. Use the toggle to switch between Full URI encoding (encodeURI) and Component encoding (encodeURIComponent).
Frequently Asked Questions
Everything you need to know about DevToolkit.
What is URL Encoding used for?
URL encoding replaces unsafe ASCII characters with a `%` followed by two hexadecimal digits. It is required when passing data via URL query strings or form submissions to ensure data isn't misinterpreted by the web server.
What is the difference between Full URI and URI Component encoding?
Full URI encoding (encodeURI) assumes the string is a complete URI and doesn't encode reserved characters that have special meaning in a URI (like : / ? @). URI Component encoding (encodeURIComponent) encodes all these reserved characters, making it suitable for encoding individual query string parameters.
Is this URL Encoder safe for sensitive data?
Yes! Like all our tools, this URL Encoder processes everything locally in your browser using JavaScript's native encoding functions. Your data is never sent to a server.
