What does the URL Encoder/Decoder tool do?

The URL Encoder/Decoder tool on PowerSEOTools.online converts normal URLs or text into URL-encoded form and decodes URL-encoded strings back to readable text. It is ideal for query parameters, redirects and web development.

What is the difference between encoding a full URL and a URL component?

When you encode a full URL, reserved characters like : / ? & and = are usually preserved. When you encode a URL component, such as a query parameter value, most special characters are encoded so the value is safe inside a larger URL.

Can this tool handle Unicode and non-English characters?

Yes. The URL Encoder/Decoder uses modern browser APIs to handle UTF-8 characters correctly, so non-English characters, emojis and symbols are safely encoded and decoded.

Are my URLs or data stored when I use this tool?

No. All encoding and decoding is done locally in your browser using JavaScript. Your input is not uploaded, stored or logged on our servers.

When should I use + instead of %20 for spaces?

The + symbol is commonly used for spaces in application/x-www-form-urlencoded data, such as HTML form submissions or some query strings. For general URL encoding, spaces are usually encoded as %20. This tool lets you choose either style.

URL Encoder/Decoder

Encode or decode URLs and query parameters for safe use in web applications. Choose encoding style, handle spaces as %20 or +, and inspect URL structure and size statistics.

Input

Tip: Paste a full URL or a single parameter value. Use Encode for text → URL-safe, and Decode for URL-encoded strings → text.

Free Online URL Encoder/Decoder Tool

The URL Encoder/Decoder from PowerSEOTools.online helps you safely prepare URLs and query parameters for use in web applications, APIs, redirects and tracking links. It converts unsafe characters into URL-encoded form and decodes encoded URLs back into human-readable text.

Why URL Encoding Matters

URLs can only contain certain characters safely. Spaces, non-English characters, emojis and some symbols must be encoded so they do not break links or cause errors. URL encoding replaces unsafe characters with a % followed by two hexadecimal digits (for example, a space becomes %20).
