Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
URL Encoder / Decoder only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
Frequently Asked Questions
- When do I need URL encoding?
- Whenever text goes into a query string, path segment or form value. Characters like spaces, & and ? have special meaning in URLs and must be encoded.
- What is the difference between + and %20?
- Both represent a space. %20 is correct in any part of a URL, while + only means space inside a query string.
