What is URL decoding?

URL decoding converts percent-encoded characters like %20 back into readable text such as spaces.

When should I use encodeURIComponent?

Use encodeURIComponent for query parameter values and individual segments. Use encodeURI for a complete URL that already contains separators.

In application/x-www-form-urlencoded data, plus signs often represent spaces. Enable plus-to-space decoding when working with form query strings.

Decode or encode URL text instantly. This free URL encoder/decoder supports full links, query parameters, and line-by-line processing.

Quick examples:

Paste your string into the input field.
Click Decode URL or Encode URL.
Use the mode selectors if you are processing a full URL versus a parameter value.
Copy the result or generate a share link for teammates.

encodeURIComponent is best for parameter values like q=....
encodeURI is best for whole URLs that already include separators.
If you see malformed sequence errors while decoding, check whether the input is partially encoded.

Can I decode multiple URLs at once?

Yes. Enable Process line by line to transform each line independently.

Does this tool send my data to a server?

No. Encoding and decoding run directly in your browser.

What is the difference between decodeURI and decodeURIComponent?

decodeURIComponent decodes parameter values aggressively. decodeURI is safer for already structured full URLs.
