What is URL Encoder & Decoder Online?

URL encoding (percent-encoding) converts characters that are unsafe or have special meaning in URLs into a `%XX` format. Spaces become `%20` or `+`, ampersands (`&`) become `%26`, and so on. This is essential when embedding arbitrary values in query strings to prevent parsing ambiguity.

How to Use URL Encoder & Decoder Online

  1. Paste the string you want to encode or decode.
  2. The result is computed instantly.
  3. Use "Encode" for strings going into URLs, "Decode" to read received URL values.

Example

URL-encoded string

Input

hello world & more

Output

hello%20world%20%26%20more

Frequently Asked Questions

What characters need to be URL encoded?

Reserved characters like &, =, +, #, ?, / and space must be encoded when used as data in URLs. Letters, digits, -, _, ., and ~ are safe and do not need encoding.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL, leaving / and : untouched. encodeURIComponent encodes everything — use it for individual query parameter values.
