Frequently Asked Questions

Common questions about this tool

encodeURIComponent encodes all special characters including /, ?, &, = (for query parameter values). encodeURI leaves these intact (for full URLs). Use Component for values, URI for complete URLs.

URLs can only contain certain characters. Spaces, non-ASCII characters, and reserved symbols (&, =, ?) must be encoded to prevent breaking the URL structure or causing security issues.
