About this tool

What is 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.

Frequently asked questions

Questions about URL Encoder

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.
