Frequently Asked Questions
What is URL encoding?
URL encoding (also called percent-encoding) replaces special characters in URLs with percent signs followed by their hexadecimal values. For example, a space becomes %20 and an ampersand becomes %26. This ensures URLs are valid and properly interpreted by web servers.
What's the difference between encodeURI and encodeURIComponent?
encodeURI encodes a complete URI, preserving characters that are valid in URLs (like /, ?, #, &). encodeURIComponent encodes individual URI components more aggressively, encoding characters like & and = that have special meaning in query strings. Use encodeURIComponent for encoding individual parameter values.
When should I URL encode data?
You should URL encode data whenever you're building query parameters, form data for POST requests, or including user-generated content in URLs. Common cases include search queries, API parameters, and redirect URLs.
