When should I encode a URL?

Encode query parameter values that may contain special characters like spaces, &, =, or non-ASCII text. For example, a search query "hello world" should be encoded as "hello%20world" before being appended to a URL.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL and leaves characters like /, ?, &, = intact. encodeURIComponent encodes a component (like a query value) and encodes those characters too. Use encodeURIComponent for individual parameter values.

Can it decode multiple URLs at once?

The tool processes the entire input as a single string. If you have multiple URLs, decode each one separately or use a line-by-line approach by pasting each on its own line.

URL Encoder & Decoder

The URL Encoder converts characters that are not allowed in URLs (spaces, &, =, ?, #, non-ASCII characters) into their percent-encoded equivalents using encodeURIComponent. The URL Decoder reverses this. Supports both component encoding (for query parameter values) and full URL encoding.

Text to URL-Encode

Encode query parameters before appending to URLs, or decode percent-encoded URLs from server logs and analytics exports.
