How to use
- Encode query values for safe URLs or decode copied links to inspect parameters, redirects, tracking tags, and API requests.
- Paste or type only sample data that is safe to inspect.
- Review the result before copying it into code, docs, or tickets.
How it works
URL encoding replaces reserved characters with percent-encoded sequences so values can travel safely inside a URL.
Examples
- Encode a search query before adding it to a test URL.
- Decode UTM parameters from a copied campaign link.
- Inspect an API callback URL before debugging.
FAQ
Why do spaces become percent codes?
Spaces are reserved in URLs and need encoding.
Can decoding change a link?
It only shows readable characters; copy carefully.
Should I paste private links?
Avoid links containing secrets or personal data.
What is double encoding?
It happens when already encoded text is encoded again.
Link inspection workflow
URL encoding is useful when query values contain spaces, symbols, non-English text, or reserved characters that would otherwise change the meaning of a link. Decode copied URLs when you need to inspect UTM tags, redirect targets, callback parameters, or API request examples. Be careful when copying decoded output back into another tool, because readable characters may need to be encoded again before the URL is safe to send. Avoid pasting private invitation links, signed URLs, or tokens.
Common mistakes
Many link bugs come from encoding the same value twice or decoding a value before putting it back into a URL. Compare the original link with the decoded view, then change only the parameter you are testing. This keeps redirect URLs, campaign tags, and callback values easier to review without accidentally changing unrelated parts of the address.
Security and limits
Check the final URL in the target app because some systems encode parameters automatically.
