When do I need URL encoding?
URL encoding is necessary when URLs contain special characters, spaces, or non-ASCII characters. It's required for query parameters, form data submission, and when passing URLs as parameters to other URLs.
What's the difference between encoding spaces as + vs %20?
Both are valid: %20 is the standard percent-encoding for spaces, while + is a shorthand specifically for form data (application/x-www-form-urlencoded). Use + for form submissions and %20 for general URL encoding.
Is my data secure when using this tool?
Yes, absolutely. All encoding and decoding happens entirely in your browser using JavaScript. Your URLs and data never leave your device or get sent to any server.
Can I encode entire URLs or just parameters?
You can encode both. Use "Full Component Encoding" for entire URLs, or disable it to encode only the query parameters and values while preserving the URL structure.
How does query parameter sorting work?
The tool can alphabetically sort query parameters in URLs, which is useful for creating canonical URLs, comparing URLs, or organizing parameters for better readability.
