Paste a URL, query value, or form field to encode reserved characters, decode percent escapes, handle plus-as-space input, and copy the browser-generated result.

Inputs are processed in the browser for this static MVP. Avoid pasting secrets into any online tool unless you understand the environment.

FAQ

Is URL encoding the same as encryption?

No. URL encoding makes text safe for URLs and form fields; it does not hide, encrypt, or protect the content from readers.

What happens if encoded text is invalid?

The decoder shows an error instead of guessing the intended output. This helps you catch broken percent escapes before pasting them into a link.

Which encode mode should I choose?

Use component mode for one query value, full URL mode when the link separators should stay readable, and form mode when spaces need to become plus signs.

Does the tool upload URLs?

No. The encode and decode actions run in the browser, so pasted examples and draft links do not need to leave the page.
