About This Tool
Percent-encode a string for safe use in URLs. Encodes reserved characters (?, &, =, #, /, etc.) and non-ASCII characters to their percent-encoded equivalents.
Follows RFC 3986. Unreserved characters (A-Z, a-z, 0-9, -, _, ., ~) are not encoded.
Why Use This Tool
- URL Construction — Encode query parameter values before constructing URLs programmatically.
- Form Data — Encode form field values for application/x-www-form-urlencoded submissions.
Frequently Asked Questions
Are spaces encoded as + or %20?
Spaces are encoded as %20 (RFC 3986). Use form encoding mode for + encoding.
Are slashes encoded?
Yes — all reserved characters including / are encoded. Use this for encoding individual components, not full URLs.
