URL Encoder / Decoder

What is URL Encoding?

URL encoding (percent-encoding) replaces unsafe characters with a "%" followed by their hexadecimal representation. This ensures URLs are transmitted correctly over the internet, as URLs can only contain ASCII characters.

When to Use URL Encoding

• Query parameters with spaces or special characters
• File names with non-ASCII characters
• Form data submitted via GET method
• API requests with special characters

Encode vs encodeURIComponent

encodeURI encodes a full URI, preserving characters like :, /, ?, #, &. encodeURIComponent encodes everything except letters, digits, and - _ . ~, making it suitable for encoding individual query parameter values.
