URL Encoder — Free Online Tool
Percent-encode text so it is safe to use inside URLs and query strings.
About URL Encoder
The URL Encoder percent-encodes text so it can be safely placed inside URLs, query strings, and form submissions. Characters such as spaces, ampersands, and non-ASCII symbols are converted into their %XX equivalents, preventing broken links and malformed requests.
It mirrors the standard encodeURIComponent behavior used across the web, making it reliable for building API calls and share links. Everything is processed locally in your browser, so your input stays private and the result is ready to copy instantly.
How to Use URL Encoder
- Type or paste the text you want to encode into the input box.
- Click 'Encode' to percent-encode the text for use in URLs.
- Review the encoded string in the output box.
- Use 'Copy Result' to copy the encoded URL to your clipboard.

Frequently Asked Questions
What is URL encoding?
URL encoding, also called percent-encoding, replaces characters that are unsafe in URLs with a percent sign followed by hex digits. For example, a space becomes %20, ensuring the URL is transmitted correctly.
When should I encode a URL?
Encode any text that goes into a query parameter, path segment, or form value when it contains spaces, ampersands, slashes, or non-ASCII characters, so the link works reliably across browsers and servers.
What encoding does this tool use?
It uses the standard encodeURIComponent behavior, which escapes characters like spaces, &, ?, =, and #, making the result safe to drop into any part of a query string.
Is my input sent to a server?
No. Encoding runs entirely in your browser, so your text never leaves your device and remains completely private.
