Purpose: Percent-encode text for use in URLs and query strings, or decode an encoded URL back to readable text.
URL Encoder
The URL Encoder percent-encodes text so it is safe to use in URLs and query strings, and decodes encoded URLs back to readable text.
Why URLs need encoding
URLs can only contain a limited set of characters. Spaces, ampersands, question marks, and non-English letters must be percent-encoded so they don't break the address - a space becomes %20, an ampersand becomes %26. This matters whenever you build a link with parameters or pass data in a query string.
Encode components correctly
The tool encodes the way encodeURIComponent does, which is right for individual query values, and decodes any percent-encoded string back to plain text. It is essential for developers building API calls, tracking links, and search URLs. Processing happens locally.
Frequently Asked Questions
What is URL encoding?
It replaces characters that are unsafe in a URL with percent-encoded equivalents, such as %20 for a space, so links work correctly.
When do I need to URL-encode text?
Whenever you place user text, search terms, or special characters into a query string or link parameter.
What is the difference between encoding a whole URL and a component?
Encoding a component (like a single query value) escapes more characters, including & and =, which must stay literal in the overall URL structure.
Can it decode an encoded URL?
Yes. Paste a percent-encoded string and it returns the readable original text.
