About URL Encoder

Overview

The URL Encoder changes your text into a URL-safe format. URL encoding, or percent-encoding, turns characters into a format that can be sent over the Internet. It replaces unsafe characters with a "%" and two hexadecimal numbers. This is a good tool for web developers and anyone who needs to pass data in a URL.

FAQ

Why do I need to encode a URL?

You need to encode a URL to make sure it can be sent and read correctly over the internet. URLs can only have a certain set of characters. Any special characters, like spaces or ampersands, must be encoded so they do not break the URL.

What is the difference between `encodeURI` and `encodeURIComponent`?

`encodeURI()` is for a whole URL and does not encode special characters like `&` or `?`. `encodeURIComponent()` is for a part of a URL, like a search query, and does encode these special characters. Most of the time, you should use `encodeURIComponent`.

Does this tool handle international characters?

Yes, the tool handles international characters by first encoding them in UTF-8 and then percent-encoding them. This is the standard way to put non-ASCII characters in a URL.
