When should I use encodeURIComponent vs encodeURI?

Use `encodeURIComponent` when encoding a query parameter value (like `q=hello world & more`). Use `encodeURI` when encoding an entire URL without breaking `:`, `/`, and `?`.

About URL Encoder

Convert query strings and URLs into standard percent-encoded format. Choose between encodeURI (preserving URL structure) and encodeURIComponent (for query parameter values).

Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our URL Encoder operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.
