What is this thing called URL encoding?

Why should you even bother about it? URL encoding is when you change the characters in a URL so they can be read by computers. You should care about URL encoding because it helps you when you are working with websites and you need to put characters in the URL. URL encoding is important for people who make websites and for people who use the internet a lot.

It helps with characters in URLs
It makes sure the website can understand the URL
You need to understand URL encoding if you want to make your website or if you want to work with websites. URL encoding is something that you should know about if you are interested, in how the internet works.

The Rules of Web Addresses

Web addresses, which are the URLs you type into your browser have to follow some rules. These rules are set by the people who make the internet work. The characters you can use in a web address are pretty simple. You can use letters like the ones you find in a book and numbers like the ones you use to count. You can also use a few symbols like a dash, an underscore, a period and a tilde. That is it. If you want to use something like a space or a question mark or an ampersand it has to be changed first. This also goes for accents, like the ones you see in Spanish words and even emojis. All of these things have to be encoded before they can be sent across the web. This means that web addresses or URLs can only have letters, numbers and a few safe symbols, like a dash or a period.

This is what they call URL encoding or sometimes percent-encoding. URL encoding is when we take the characters and turn them into something that starts with a percent sign and then has two special numbers after it. For example:

When you have a space in something it usually gets replaced with %20.
The at sign, which is the symbol @ becomes %40.
When you see a question mark ? it becomes %3F.
The word "café" becomes caf%C3%A9.

Why You Need a URL Encoder & Decoder

When you are using the internet, your browser and the server do some things for you without you noticing. Sometimes you need to do these things yourself. You need to encode or decode URLs manually. This is where our URL tool comes in. Our URL tool helps you with this problem. You will need a URL encoder and decoder in situations, such as:

When you are sending data over the internet
When you are working with web forms
When you are trying to access a web page with characters in the address

Everyday Examples:

✅ Creating clean shareable links
So you want to make a link for a social media post. Let us say you are looking for the hiking trails in Colorado. With our tool "best hiking trails in Colorado" becomes "best%20hiking%20trails%20in%20Colorado" right away.

✅ Working with APIs or web forms
Developers usually send information through websites using URLs. For example they might use something, like this: ?name=John&city=New%20York. If the information they are sending has characters and they do not encode it the request will not work.

✅ Debugging broken links
Sometimes encoded URLs look messy or confusing. Using our URL decoder you can see right away that the link really means "red/blue shirt".

✅ Marketers and UTM tags
Marketers use UTM parameters to track campaigns. If they include values like utm_campaign=spring sale, the space must be encoded as spring%20sale or the analytics will get messy.

✅ Students & teachers learning web basics
Learning about URLs is a part of being good with computers and the internet. Our tool is great for the classroom because it is easy to use and understand.
