URL tool

URL encode/decode

Encode text into URL-safe percent encoding, or decode percent-encoded values back to readable text. Choose component-value or full-URL mode. Processing stays in your browser.

Input

Source text

Text or URL to process

Treat + as space (query values)

Output

Converted result

Encoded or decoded text

Usage examples

Encode a query value before pasting it into a link, decode a tracking URL to inspect its parameters, or convert Korean and other non-ASCII text into percent encoding.

Readable errors

Malformed input leaves the output blank and names the exact broken percent sequence, such as %E0, including where it appears.

Limitations

Component mode processes one value at a time. Full-URL mode preserves URL structure characters and never decodes them. Each run performs exactly one encode or decode pass — never two.

Privacy

Encoding and decoding happen in the browser. Text and URLs are not sent to a server by this page.
