How it works

1

Choose direction and mode

Encode percent-encodes text; Decode reverses %XX sequences. Component encodes everything unsafe for a query value. URI keeps reserved URL characters. Form uses + for spaces (x-www-form-urlencoded).

2

Paste and convert

Paste a URL, query fragment, or form value. Live mode updates as you type. Swap moves the result back to input and flips direction.

3

Copy or download

Copy the result or download a text file. Character counts show under each pane.

What is URL percent-encoding?

Percent-encoding (RFC 3986) replaces unsafe characters with % followed by two hex digits. This tool supports component encoding, full-URI encoding, and form encoding with + for spaces. Everything runs in your browser; Easy24 does not receive your input.

  • encodeURI / decodeURI for full URLs
  • Form mode with + for spaces
  • Live mode, swap, and sample
  • Copy and download
  • Unlimited use — no daily cap

Questions

What does URL Encode / Decode do?

It percent-encodes strings for URLs and query parameters, or decodes %XX sequences back to readable text.

Component vs URI mode?

Component (encodeURIComponent) encodes :, /, ?, &, = and more — use it for query values. URI (encodeURI) leaves those reserved characters so a full URL stays structured.

What is Form (+) mode?

application/x-www-form-urlencoded encoding: spaces become + instead of %20. Common in HTML form POST bodies and some query strings.

Why did decode fail?

Malformed sequences like a lone % or incomplete %XX are invalid. Fix the string or paste a valid percent-encoded value.

Is my text sent to a server?

No. Encoding and decoding run entirely in this tab.

Is there a daily limit?

No. This tool has no daily cap.

Do I need an account?

No. Open the page and use it.

Does it work on a phone?

Yes. It runs in the mobile browser.
