URL Encoder/Decoder - Online URL Encoding Tool

All processing happens in your browser. Your data is never sent to our servers.

URLs and query strings break easily when they contain spaces, emoji, or reserved characters like &, =, ?, and #—especially when you copy/paste between tools.

Encode or decode URLs and query strings instantly. Handle special characters safely in URLs.

Why you may need this tool

URLs and query strings must safely represent characters that are not allowed in plain form, such as spaces, non - ASCII letters, and reserved symbols. When you inspect logs or debugging screens, you may see percent - encoded values that are hard to read. When you build links, leaving characters unencoded can lead to broken requests or unexpected parsing. Encoding and decoding helps you move between “human - readable” values and “URL - safe” values with fewer errors.

How to use

Paste a full URL or a parameter value, then encode or decode to confirm what is actually being sent.

  1. Paste your URL or text in the input area
  2. Click 'Encode' to convert special characters to URL - safe format
  3. Or click 'Decode' to convert encoded URLs back to readable text
  4. Copy the result

Examples

Reading percent - encoded values from logs
Debug logs often show parameters like `%EA%...`. Decoding reveals the real keyword or parameter so you can reproduce the request accurately.
Building redirect or tracking URLs safely
When a parameter itself contains a URL or special characters, encoding is required. Encoding the inner value helps prevent truncation and parsing errors in different environments.

Benefits & differentiators

You can validate link parameters and reproduce issues more reliably by working with the exact encoded value. This is useful for redirects, UTM parameters, and search queries. It also reduces the risk of double - encoding or partial encoding, which often causes bugs where parameters look correct but decode incorrectly on the server side.

Who this is for

Recommended if you: - debug query strings and redirects - handle non - ASCII characters or reserved symbols in URLs - build tracking links and need stable parameters - investigate “works in one place, breaks in another” link issues

FAQ

What is URL encoding?
URL encoding (percent - encoding) converts special characters to a format that can be safely transmitted in URLs. For example, spaces become %20.
When should I use URL encoding?
Use URL encoding when you need to include special characters in URLs, query parameters, form data, or API requests.
Is my data sent to your servers?
No. All encoding and decoding happens locally in your browser. Your data stays completely private.
Does this handle international characters?
Yes, we fully support UTF - 8 encoding, which includes Korean, Japanese, Chinese, emoji, and all international characters.
What characters get encoded?
Characters like spaces, &, =, ?, #, and non - ASCII characters get encoded. Letters, numbers, and some punctuation remain unchanged.
