URL Encoder

Percent-encode text for URLs and query strings instantly.

The URL Encoder percent-encodes any text so it can travel safely inside a URL or query string. Characters like spaces, &, =, ? and # all have structural meaning in URLs; encoding turns them into safe %XX sequences, preventing broken links and malformed parameters.

The encoding is Unicode-safe: emoji, accented characters and non-Latin scripts are encoded as UTF-8 percent sequences, which is exactly what servers expect. Type a search phrase, a value with spaces and symbols, or a full parameter value, and the encoded form appears instantly.

Percent-encoding runs locally in your browser. Decoding works in reverse on the URL Decoder page — the pair covers every 'why is my link breaking' debugging session.

How to use the URL Encoder

  1. Type or paste the text you want to put into a URL.
  2. Read the percent-encoded result instantly.
  3. Copy the encoded value into your query string or link.
  4. Notice how spaces become %20 and & becomes %26.
  5. Use the decoder page to reverse the process when needed.

Frequently asked questions

Why do I need to encode URLs at all?

URLs reserve certain characters as syntax: / separates paths, ? starts the query, & separates parameters, # starts the fragment. A value containing any of these must be encoded or the URL will be parsed incorrectly — breaking your links or parameters.

What does %20 mean?

It is the percent-encoding of a space (hex 20). Encoding converts each special byte to % followed by its two hex digits, so 'hello world' becomes 'hello%20world'.

Is this the same as HTML encoding?

No. URL encoding uses %XX sequences for URL contexts; HTML encoding uses entities like & for markup. Using the wrong one produces double-encoded or broken output — this tool handles the URL flavor.
