URL Encoder

Percent-encode any text so it is safe inside a URL query string or path segment.

🔒 Your file is processed locally in your browser whenever supported. This tool runs entirely on your device — nothing you type or upload is sent to a server, logged, or stored.

Why use URL Encoder?

Standard encodeURIComponent behaviour
Safe for query values, path segments and form bodies
Handles unicode and multi-byte characters correctly
Encoding runs locally — content is not sent anywhere

How to use URL Encoder

Paste the raw text you need to place in a URL.
Press Execute to produce the percent-encoded string.
Copy the result into your query string or API client.
Use the decoder if you need to reverse an encoded value.

Frequently asked questions

What is the difference between %20 and + for spaces?

+ is traditional for application/x-www-form-urlencoded bodies. %20 works in both query strings and paths. This encoder uses encodeURIComponent (%20), which is the safer general choice.

Which characters must be encoded in a query value?

At minimum: space, #, &, +, =, ?, %, and non-ASCII. encodeURIComponent escapes all of these plus !, ', (, ) and * — all safe to leave encoded.

Can I encode an entire URL?

You can, but you usually should not. Encode only the parameter values, not the scheme, host or path separators. Encoding a whole URL breaks navigation.
