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.
