URL Encode
Encode text and special characters for safe use in URLs. URL encoding (percent encoding) converts special characters to their percent-encoded equivalents. Essential for creating valid URLs, query parameters, and handling special characters in web development.
When to use this tool
You need to safely include user input in URLs or query parameters.
You are building request URLs with special characters.
Examples
Encode a query value
Input
status=needs review & priority=high
Output
status%3Dneeds%20review%20%26%20priority%3Dhigh
Encode only the parameter value when building URLs.
Developer use cases
Encode search queries before appending to URLs.
Prepare payloads for GET requests or redirect links.
Common mistakes to avoid
Encoding an entire URL when you only need to encode a query value.
Double-encoding values (e.g., encoding % into %25 twice).
Format and behavior notes
Space becomes %20; special characters are percent-encoded.
Use URL decoding to reverse the process.
