URL Encoder/Decoder
Safely encode query values or decode URL-encoded strings locally.
Paste data here. It stays in your browser.
Copy-ready result appears here.
How it works
- Runs encodeURIComponent.
- Attempts decodeURIComponent.
- Returns both views.
Common use cases
- Prepare query parameters.
- Debug callback URLs.
- Decode tracking links.
Code example
encodeURIComponent('hello world')Encode query values
Special characters such as spaces, ampersands, slashes, and equal signs can change URL meaning unless they are encoded correctly.
Decode carefully
Decoded URLs can reveal redirect destinations or tracking parameters. Review them before sharing.
FAQ
Is my input uploaded?
No. This MVP runs tool logic in your browser and does not send tool input to a server.
Can I use this on mobile?
Yes. Pages are mobile-first and designed for quick copy, paste, and share workflows.
Does the tool store history?
No. The MVP does not store tool input history or create user accounts.
Should I verify important output?
Yes. These tools are designed for productivity, but production changes and financial decisions should be independently verified.
Can the tool run after the page loads?
Yes. The interactive logic runs in the browser once the static page and JavaScript island are loaded.
What input format should I use?
Use the examples on the page as a starting point, then replace them with your own local input.
