Frequently asked questions

Is URL Encoder & Decoder free?

Yes. ToolNest provides URL Encoder & Decoder as a free browser-based utility.

Does URL Encoder & Decoder require an account?

No account is required. Open the tool and use it directly in your browser.

When should I use encodeURI instead of encodeURIComponent in URL Encoder & Decoder?

Use encodeURI when you are encoding a complete URL and want characters such as colon, slash, question mark, ampersand, and equals to keep their URL meaning. Use encodeURIComponent for a query parameter, path segment, form value, or any single component that must not leak separators.

Why does URL Encoder & Decoder have form plus encoding?

HTML form URL encoding commonly represents spaces as plus signs. The form plus mode encodes text like encodeURIComponent, then converts %20 spaces to + so values are easier to compare with application/x-www-form-urlencoded query strings.

Can URL Encoder & Decoder process multiple URLs or query parameters at once?

Yes. Switch batch mode to process each line, and every line will produce encodeURI, encodeURIComponent, form plus encode, and decode results with a copyable report.

How do I use URL Encoder & Decoder?

Open the URL Encoder & Decoder page, enter or paste your values, use the visible controls, and copy the result from the first working area. It is grouped with Encoding & Parsing for quick browsing.
