The Internet has become an integral part of human life in today's era. We visit websites every day, shop online, use social media and get information through various applications. The most basic thing in this whole process is the URL (Uniform Resource Locator), which is called a web address in common language. But sometimes we need to create or share such links. Which include spaces, special characters or non-English characters like Urdu. In such a case, URL Encoder helps us.

In this article, we will see in detail what is URL Encoder, how it works, what is its importance and where it is used in practical life.

What is the URL?

A URL is actually a web address that provides access to a specific web page or resource. For example:

https://www.example.com/articles/seo-guide

This is a simple URL that includes the domain name and the path to the web page. But if the same address contains spaces or special characters, it becomes difficult for the browser to understand it. This is where URL Encoding is needed.

What is URL Encoding?

URL Encoding is the process of converting special characters, spaces, or non-English characters into a format that the web can understand. In this process, each special character is replaced with a specific code, which is usually called percent encoding.

For example:

Space is converted to %20.

The & symbol is converted to %26.

The ? symbol is converted to %3F.

So if your original link is:

https://www.example.com/search?query=seo tips

The URL Encoder will convert it to this format:

https://www.example.com/search?query=seo%20tips

Now the link is understandable to the browser and will work correctly.

Why is URL Encoder necessary?

Special characters often cause problems when sharing data over the Internet. If they are not encoded:

The browser may misread the link and the link may break due to spaces or symbols.

The server may misunderstand the data because the query parameters are not clear.

Security issues can arise because hackers can add malicious code to the link without encoding.

The user experience is affected because the user's trust is reduced if the link does not open correctly.

Therefore, using a URL Encoder is essential to make the links safe, correct, and effective.

How does URL Encoder work?

URL Encoder works primarily on ASCII (American Standard Code for Information Interchange) format. Except for English letters (A-Z, a-z, 0-9) and a few reserved symbols (such as -, _, . and ~), all other characters have to be encoded.

This process is done in three steps:

Character identification – The encoder checks which characters are not reserved.

Hexadecimal conversion – The character is converted to its Unicode or ASCII value in hexadecimal.

Displaying with preset sign – % is prefixed to the hexadecimal value.

Example:

Space → ASCII value 32 → Hex 20 → %20

Question mark (?) → ASCII value 63 → Hex 3F → %3F

Practical uses of URL Encoder

1. Search Engine Optimization (SEO)

If you want to include words in Urdu or other languages ​​in your website URLs, URL Encoder converts them into the correct format so that search engines can read them easily.

2. Web Development

Form data in web applications often contains special characters. When this data is sent to the server via URL, encoding is required so that the data arrives correctly.

3. API Calls

When we send or receive data through APIs, it is necessary to use URL Encoding, otherwise the API will not accept the request.

4. Social Media and Messaging

When we share links on social media or chat apps, many times special characters break the link. With encoding, the link always remains valid.

5. Security

Encoding can prevent malicious code from being directly executed, making web applications more secure.

Difference between URL Encoder and URL Decoder

URL Encoder: Converts special characters into safe codes.

URL Decoder: Converts the same codes back into the original characters.

Example:

Encoded URL:

https://www.example.com/search?query=seo%20tips

Decoded URL:

https://www.example.com/search?query=seo tips

Benefits of URL Encoding

Link integrity – No special characters break the link.

Server-client consistency – Data arrives exactly as the user entered it.

International language support – Words from Urdu, Arabic or other languages ​​can also be included in the link.

User experience is improved – Links always work and the user remains satisfied.

Example: URL Encoding with Urdu Words

Suppose you create a page on your website with the following link:

https://www.example.com/content/URL-Encoder

If you paste it directly into the browser, the link may not open correctly. But when you encode it, it will look something like this:

https://www.example.com/%D9%85%D8%B6%D9%85%D9%88%D9%86/%DB%8C%D9%88-%D8%A2%D8%B1-%D8%A7%DB%8C%D9%84-%D8%A7%D9%86%DA%A9%D9%88%DA%88%D8%B1

Now this link is completely valid and safe.

Conclusion

URL Encoder is a basic but very important tool in the world of the internet. It converts special characters and languages ​​into a format that web browsers can understand, making links safe, valid, and usable. Whether you are a web developer, SEO expert, or a regular user, URL Encoding is a must-have for you. If we look at its benefits, it not only makes links valid but also improves security and user experience.
