What is URL encoding and why is it important?

URL encoding converts special characters to a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and non-ASCII characters are converted to %XX format to prevent misinterpretation by web servers and browsers.

When should I use URL encoding?

Use URL encoding when sending data through URLs, query parameters, form submissions, or API calls. It's essential for web development, especially when dealing with user input that may contain special characters.

What's the difference between encodeURI() and encodeURIComponent()?

encodeURI() is used for encoding entire URLs, while encodeURIComponent() is used for encoding individual components like query parameters. This tool uses encodeURIComponent() for maximum safety.

Can this tool handle Unicode characters?

Yes, the tool properly handles Unicode characters by converting them to their UTF-8 byte sequences and then percent-encoding them, ensuring compatibility across different systems and browsers.

Is URL decoding always safe?

URL decoding is generally safe for displaying data, but always validate and sanitize decoded content before using it in security-sensitive operations to prevent injection attacks.

What characters get encoded?

Characters that get encoded include spaces, special symbols (!@#$%^&*()), non-ASCII characters, and reserved characters used in URLs. Each character is converted to %XX format where XX is the hexadecimal representation.

How it works: URL encoding (percent-encoding) converts characters that are not allowed in URLs into a % followed by two hexadecimal digits. For example, a space becomes %20, and & becomes %26. Uses encodeURIComponent() which encodes all characters except A–Z, a–z, 0–9, -, _, ., !, ~, *, ', (, ).
