URL Encoder

Encode URLs and strings to percent-encoded format. Ensure special characters are safely transmitted in web addresses and query parameters.

About URL Encoder

URL encoding (percent-encoding) converts characters into a format that can be transmitted over the internet. Special characters, spaces, and non-ASCII characters are replaced with a percent sign followed by hexadecimal values. This tool encodes both full URLs and individual components, helping you construct valid web addresses and API requests.

How to Use URL Encoder

  1. Paste the text or URL you need to encode.
  2. Choose between 'Encode Full URL' or 'Encode Component' mode.
  3. Click 'Encode' to generate the percent-encoded result.
  4. Copy the encoded output for use in your application.

Frequently Asked Questions

What is the difference between encodeURI and encodeURIComponent?

encodeURI is meant for full URLs and preserves characters with meaning in URLs (like ? and &). encodeURIComponent is for query parameters and encodes almost all special characters.

Should I encode spaces as %20 or +?

In URLs, spaces are typically encoded as %20. The plus sign (+) is used in application/x-www-form-urlencoded data such as HTML form submissions.

Does this handle Unicode characters?

Yes. Non-ASCII characters are encoded using UTF-8 percent-encoding, which is the modern web standard.
