How to Use the URL Encoder / Decoder

Encode or decode URLs and query parameters in three steps

Enter Your URL or Text

Paste a full URL, a query string, or any text into the Input URL / Text field. You can paste an encoded URL to decode it, or a plain URL with special characters to encode it.

Choose the Right Operation

Use the sidebar buttons: Encode URL encodes the entire URL preserving its structure; Decode URL converts percent-encoded characters back to plain text; Encode Component encodes every special character including /, ?, & �� ideal for query parameter values.

Review and Copy

The result appears in the Result panel below. Check the status message for confirmation. Use Copy Result to copy it, or Swap to exchange input and output for a quick round-trip test.

🎯

Encode URL vs. Encode Component

encodeURI preserves URL structure characters (/ ? & = #). encodeURIComponent encodes everything �� use this for individual query parameter values.

SEO Tracking URLs

When building UTM-tagged URLs for campaign tracking, encode the parameter values to ensure special characters don't break your links.

⚠

Double Encoding

Watch out for double-encoded URLs. If %20 becomes %2520, the URL was encoded twice. Use Decode to normalize it back.

Common Questions

URLs can only contain a limited set of characters from the ASCII character set (RFC 3986). Characters outside this set �� like spaces, non-Latin letters, emojis, and certain punctuation �� must be percent-encoded to safely transmit them. For example, a space becomes %20, and Chinese characters become sequences like %E4%BD%A0.

encodeURI (our Encode URL button) preserves characters that have special meaning in a URL structure: , / ? : @ & = + $ #. It's designed to encode a complete URL. encodeURIComponent (our Encode Component button) encodes these special characters too �� use it for encoding individual query parameter values or path segments.

Yes. Simply copy and paste only the portion you want to encode. For example, if you need to encode only the query parameter value, paste just that value and use Encode Component. The result can then be manually inserted back into your URL.

About URL Encoding

What Is URL Encoding (Percent-Encoding)?

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts characters that are not allowed in a URL into a format that can be transmitted over the Internet. The encoding replaces unsafe ASCII characters with a % followed by two hexadecimal digits representing the character's byte value.

Characters That Always Need Encoding

Space: Encoded as %20 (not +, which is form-encoding).
Non-ASCII characters: UTF-8 encoded and then percent-encoded byte-by-byte. E.g., �� becomes %C3%A9.
Reserved characters in wrong context: #, ?, &, = should be encoded when not used as delimiters.
Unsafe characters: <, >, ", {, }, |, \, ^, ` should always be encoded.

Why Proper URL Encoding Matters for SEO

For SEO professionals, properly encoded URLs ensure that tracking parameters (UTM tags), affiliate links, and redirect URLs work correctly across all browsers and platforms. Broken or double-encoded URLs can result in lost attribution, incorrect analytics data, and poor user experience. Always validate URLs after encoding, especially when working with internationalized domain names or non-Latin characters.
