URL Encoder/Decoder
About this Tool
Ensure your URLs are always safe and valid. Our URL Encoder/Decoder makes it easy to convert strings with special characters (like spaces, `&`, or `?`) into a format that can be safely transmitted over the web. It's an essential tool for developers building APIs, marketers creating campaign links, or anyone who needs to handle complex URLs.
URL encoding, also known as percent-encoding, replaces unsafe characters with a `%` followed by their two-digit hex code. This prevents browsers and servers from misinterpreting your URLs. Our tool uses the standard `encodeURIComponent` function for maximum safety and compatibility.
- Paste your string or URL into the input box.
- Click 'Encode' to convert it into a URL-safe format.
- To reverse the process, paste an encoded string and click 'Decode'.
- Building a search query with user-generated input.
- Creating a link with special characters in the parameters.
- Debugging a malformed URL from a server log.
- Safe & Reliable: Uses the standard `encodeURIComponent()` function.
- Handles All Special Characters: Correctly encodes spaces, symbols, and more.
- Instant Results: Real-time encoding and decoding.
- Simple Interface: Clean, fast, and easy to use.
Following the RFC 3986 standard, URL encoding ensures that data in a URL is correctly interpreted. Reserved characters (like `?` and `&`) have special meanings, so they and other non-standard characters must be encoded to be treated as literal data.
What's the difference between this and `encodeURI`?
`encodeURIComponent` is safer because it encodes more characters. It's best for encoding individual URL parameters, while `encodeURI` is for encoding a full URL.
How are spaces handled?
Spaces are typically converted to `%20` or `+`, depending on the context. Our tool uses `%20` for broad compatibility.
Is it safe for full URLs?
It's safest to encode only the components of a URL, not the entire thing, as that can break the `http://` part.
All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
