Three useful modesEncode a URL component, preserve full-URL delimiters, or use form/query-value encoding where spaces become +.
Unicode awareJavaScript URI encoding converts Unicode text to standards-compatible UTF-8 percent escapes and reports malformed input clearly.

URL component

Use this for individual query values, path segments, or other data that should escape reserved URL punctuation.

Full URL

Encode unsafe characters while preserving URL structure such as the scheme, slashes, query separators, fragment marker, and assignment characters.

Form / query value

Use application/x-www-form-urlencoded style text where spaces are represented as + and literal plus signs are safely escaped.

Base64 Encoder / Decoder Encode UTF-8 text to Base64 or decode Base64 back to text directly in your browser, including Base64URL support. URL / Slug Generator Generate clean readable URL slugs from titles or text with configurable separators and browser-local normalization.
