Why URL Encoding?

URLs can only contain a limited set of ASCII characters. Special characters like spaces, ampersands, and non-ASCII characters must be percent-encoded to be safely included in URLs and query strings.

  • Safely pass parameters in URL query strings.
  • Handle international characters in URLs.
  • Debug encoded URLs from logs or analytics.
  • Build API requests with special characters.

Component vs Full URI

Component Mode

Uses encodeURIComponent which encodes all special characters including :, /, ?, and &. Best for encoding individual query parameter values.

Full URI Mode

Uses encodeURI which preserves URL-safe characters like :, /, ?, and &. Best for encoding a complete URL while keeping its structure intact.
