Frequently Asked Questions

What is URL encoding and why is it needed?

URL encoding (also called percent-encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and non-ASCII characters are converted to percent signs followed by hexadecimal codes (e.g., space becomes %20). This ensures URLs work correctly across all browsers and systems.

When should I encode URLs vs decode them?

Encode URLs when you need to include special characters in query parameters, form data, or API requests. Decode URLs when you receive encoded data and need to read it in human-readable format, or when debugging web applications and analyzing URL parameters.

Is this tool safe to use with sensitive data?

Yes! All encoding and decoding happens entirely in your browser using JavaScript. No data is sent to our servers or stored anywhere. Your URLs and text remain completely private and secure on your device.

What characters are typically encoded in URLs?

Common characters that get encoded include: spaces (%20), ampersands (%26), question marks (%3F), hash symbols (%23), plus signs (%2B), equals signs (%3D), and non-ASCII characters like accented letters. Reserved characters used in URL structure are encoded when they appear in data rather than as delimiters.

Can I use this tool for form data and API parameters?

Absolutely! This tool is perfect for encoding form data, API parameters, query strings, and any text that will be included in URLs. It's commonly used by web developers for testing APIs, debugging web applications, and preparing data for HTTP requests.
