URL Encoder & Decoder guide

Percent-encoding replaces characters that have special meanings in URLs with UTF-8 byte sequences written as percent escapes.

Your input is processed in the current browser tab and is not sent to the application server.

Why use this tool?

Inspect or transform developer data without installing another utility.
Copy a clean result directly into code, a terminal, an API client, or documentation.
Keep routine developer work in one fast, consistent interface.

Common use cases

Encoding a query parameter value
Inspecting an encoded redirect or callback URL
Preparing safe path segments and form values for testing

How to use it

1
Select encoding or decoding.
2
Choose whether the input is one component or a complete URL.
3
Paste the value and inspect the result.
4
Copy the transformed output.

URL component

Component mode encodes separators such as ampersands, equals signs, slashes, and question marks because they may be data rather than URL structure.

Complete URL

Complete URL mode preserves structural separators while encoding spaces and other unsafe characters.

Decoding errors

A percent sign must be followed by two hexadecimal digits, and byte sequences must form valid encoded text.

Practical tips for better results

Encode parameter values individually before joining a query string.
Avoid double encoding an already encoded value.
Use URLSearchParams in application code when constructing real request URLs.

Frequently asked questions

Does the URL Encoder & Decoder upload my data?

No. The transformation runs locally in your browser. Avoid pasting secrets into any tool you do not control, and clear the fields when using a shared device.

Can I use the result in production?

You can copy or download the result, but review it in the context of your application and run the project-specific tests or validation required by your workflow.
