URL Encoder
Encode URLs and parameters
What Is a URL Encoder?
A URL encoder converts special characters, spaces, and non-ASCII text into percent-encoded format safe for use in URLs. Spaces become %20, special characters become %XX, and non-ASCII characters become multi-byte sequences. Tooliva's free online URL encoder makes any text URL-safe instantly in your browser.

Frequently Asked Questions
Q: When do I need URL encoding?
Anytime you include spaces, special characters, or non-ASCII text in a URL. Common cases include query parameters, form submissions, and redirect URLs.
Q: What is the difference between encoding a component and a full URL?
Component encoding encodes only special characters. Full URL encoding also encodes reserved URL characters like /, ?, and &. Use component encoding for individual parameters.

Yes. Use the URL Decoder to convert percent-encoded URLs back to readable text.
Q: Is the encoding private?
Yes. All encoding happens in your browser. Your text never leaves your device.
