Encode text for safe use in URLs, query strings, parameters, redirects, and API requests.
Use this free URL Encoder to convert unsafe characters into percent-encoded text for URLs, query parameters, redirects, and request values. It is useful when preparing links, encoding spaces and symbols, building tracking URLs, debugging API calls, and making sure special characters are transmitted safely inside web addresses. Paste text or a full URL to encode it instantly in the browser.

Use url encoder when you need a fast browser-based result without extra setup. It works well for quick checks, one-off tasks, and routine formatting or calculation work.
URL Encoder converts readable text into percent-encoded output. URL Decoder does the reverse and turns encoded text back into readable form. If you are starting with raw text, encode it. If you are starting with encoded text, decode it.
URL Encoder is for making text safe inside URLs and query parameters. Base64 Encoder converts text into a different transport format and is not a substitute for normal URL escaping. If the destination expects a URL-safe value, URL encoding is usually the correct choice.
If you need to reverse an encoded result, use URL Decoder. If you want to inspect the structure of a full link, open URL Parser. If your encoded value contains JSON text, you may also want JSON Formatter.

Useful when spaces must be safe inside a URL or parameter value.
Input
name=John & role=admin
Output
name%3DJohn%20%26%20role%3Dadmin
Helpful when building parameter values that contain equals signs, ampersands, or spaces.
Input
https://example.com?a=1&b=2
Output
https%3A%2F%2Fexample.com%3Fa%3D1%26b%3D2
Useful when a URL itself needs to be passed as a parameter value.
Input
https://example.com/login?next=/dashboard
Output
https%3A%2F%2Fexample.com%2Flogin%3Fnext%3D%2Fdashboard
Useful for redirect flows where one URL must be safely embedded inside another.
Input
email=user@example.com?x=1&y=2
Output
email%3Duser%40example.com%3Fx%3D1%26y%3D2
Helpful for debugging how reserved characters are encoded before sending them.
Input
Hello world
Output
%D0%9F%D1%80%D0%B8%D0%B2%D0%B5%D1%82%20%D0%BC%D0%B8%D1%80
Useful when non-English text must be included in a link or parameter safely.
Input
{"name":"John","role":"admin"} Output
%7B%22name%22%3A%22John%22%2C%22role%22%3A%22admin%22%7D
Useful when sending structured text through a query parameter.
Input
line one line two
Output
line%20one%0Aline%20two
Helpful for checking how multiline text is represented after URL encoding.
Fix: Decide whether you need to encode the whole string or just one parameter value before copying the result.
Fix: Use Base64 tools only when the target system specifically expects Base64, not percent-encoded text.
Fix: Decode the value first or confirm whether it has already been encoded before running the tool again.
Fix: Reserved characters may be encoded depending on the context and how the value will be used.
Fix: Trim the input first if exact encoded output matters.
A URL encoder converts unsafe or reserved characters into percent-encoded text so they can be used safely inside URLs and parameters.
Use URL encoding when text contains spaces, symbols, Unicode characters, or reserved characters that must be transmitted safely in a URL.
URL Encoder converts readable text into percent-encoded text, while URL Decoder turns encoded URL text back into readable form.
URL encoding makes text safe for use inside URLs, while Base64 converts text into a different encoded format for data transport or storage.
That depends on the use case. Often only the parameter value should be encoded, but sometimes a full URL must be encoded when it is embedded inside another URL.
The most common reason is double-encoding, where a value that was already encoded gets encoded again.
Yes. URL encoding is useful for making international text safe inside query strings and other URL contexts.
Yes. If JSON text needs to be passed as a query value, it can be URL-encoded.
Spaces are not safe as raw characters in many URL contexts, so they are encoded into their percent-encoded representation.
Use URL Decoder when you want to reverse the encoded result or verify that the encoded value round-trips correctly.
