URL Encoder / Decoder

Percent-encode URL parameters or decode encoded links back to readable text.

About the URL Encoder / Decoder

The URL Encoder and Decoder converts text to and from the percent-encoded format that web addresses require. When a URL contains spaces, ampersands, or other special characters, they must be encoded so browsers and servers interpret them correctly. This tool lets you encode a query parameter for safe inclusion in a link, or decode a messy encoded URL into something you can actually read.

The conversion runs entirely client-side, so any links or parameters you process, including those with private query values, are never uploaded. There is no signup and no fee. It is a quick companion for developers building API requests, debugging redirects, and inspecting tracking links that have been encoded beyond recognition.

Frequently asked questions

Why do URLs need encoding?
Characters like spaces, ampersands, and slashes have special meaning in URLs, so they are percent-encoded to be transmitted safely without breaking the link.
Can I decode a link someone sent me?
Yes. Paste the encoded URL and choose decode to convert the percent-encoded characters back into readable text.
Does it encode the whole URL or just parameters?
You can encode any text, whether it is a single parameter value or a longer string, depending on what you paste in.
Is my URL data kept private?
Yes. The tool runs in your browser, so the URLs and parameters you process are never sent to a server.
