URL Encoder
Encode special characters for safe URLs
What is URL Encoder?
URL Encoder converts special characters in a string into percent-encoded (%XX) format so they can be safely included in URLs and query parameters.
When to use this tool
- Encoding query parameter values for HTTP requests
- Preparing form data for URL submission
- Encoding file names for URL paths
- Making user input safe for inclusion in URLs
How it works
Each character is checked: if it's an unreserved character (A-Z, a-z, 0-9, -, _, ., ~), it's kept as-is. All other characters are replaced with % followed by their two-digit hexadecimal byte value.
