How to Encode and Decode URLs Without Breaking Them
Choose the right URL context
URL component
Use this for one value, such as a query value, path segment, redirect URL, or fragment value.
Full URL
Use this when you want the URL to stay readable and keep separators like slash, question mark, ampersand, and hash.
Form/query value
Use this when the text comes from form-encoded data and plus signs should be treated as spaces.
Common mistakes
Encoding a full URL as one value
Component encoding escapes URL separators. That is useful inside one query value, but it can make a whole URL harder to read or use.
Missing a second decode
Some redirect values and logs are encoded more than once. If the output still has patterns like %20, try recursive decode.
Forgetting plus-as-space rules
A plus sign means space in form-encoded query text, but not in every URL context. Switch modes before trusting the output.
Tips
Inspect query values
After decoding a full URL, check the parsed query section to see each key and value separately.
Use line mode for lists
Line mode keeps a list of separate URLs or values in the same shape while each line is converted.
Remove secrets before sharing
The tool runs in your browser, but copied URLs can still expose tokens, passwords, and private IDs.
