Online URL Encoder
Percent-encode URLs, query parameters, and reserved characters
Tip: For query parameter values (e.g. search terms or names), use Component Mode so reserved characters like &, ?, and = are encoded.
What Is URL Encoding?
URL encoding, also called percent-encoding, converts characters in a URL into a format that can be safely transmitted and interpreted as part of a web address.
Some characters have special meanings within URLs. For example, spaces, reserved characters, and certain symbols may need to be represented using percent-encoded values.
A URL encoder replaces characters that need encoding with their corresponding percent-encoded representation.
Here, the space character is represented as %20.
URL encoding is commonly used when working with query parameters, form data, API requests, redirects, tracking URLs, and dynamically generated links.
How to Encode a URL
Follow these simple steps for quick online URL encoding without requiring you to install software or write code.
- 01
Enter or paste your text
Paste your destination URL, query string, or parameter value into the input box.
- 02
Choose encoding mode
Select Component mode (for query params) or Full URL mode (to preserve path delimiters).
- 03
Automatic instant conversion
The tool percent-encodes characters into URL-safe hex codes in real time.
- 04
Copy and use your result
Copy the encoded output directly to your clipboard or send it to the Lnkeee shortener.
What Does a URL Encoder Do?
A URL encoder converts characters that may not be safely represented in a URL into their percent-encoded form.
| Character | Encoded value | Description |
|---|---|---|
| Space | %20 | Standard space in RFC 3986 |
| # | %23 | URL fragment identifier |
| % | %25 | Percent escape character |
| ? | %3F | Query string beginning |
| & | %26 | Query parameter separator |
| = | %3D | Key/value delimiter |
| + | %2B | Plus sign / alternate space |
| / | %2F | Path segment separator |
| : | %3A | Scheme delimiter |
The exact characters that should be encoded depend on where they appear in a URL and how the URL is being constructed.
This is particularly important for query strings. A value containing characters such as &, =, #, or spaces can otherwise be interpreted as part of the URL structure rather than as part of the value itself.
URL Encoding Example
Suppose you want to send the following search value as a URL parameter:
If placed directly into a query string, the & character can be interpreted as a separator between parameters.
A URL-encoded version is:
The encoded value can then be safely used as the parameter value:
This distinction is important when constructing URLs programmatically or manually.
When Should You Encode a URL?
URL encoding is useful whenever URL data contains characters that need to be represented in a URL-safe form. Common situations include:
Query parameters
When a URL contains user-provided search terms, names, addresses, or other values, those values may need to be encoded before being added to the query string.
API requests
APIs frequently use URL parameters to transmit values. Encoding parameter values helps ensure that special characters are interpreted correctly.
Form data
URL encoding is also associated with form submissions, particularly data using the application/x-www-form-urlencoded format.
Tracking URLs
Marketing and analytics URLs can contain multiple parameters and values. Proper encoding helps prevent special characters within parameter values from interfering with the URL structure.
Dynamically generated links
Web applications frequently construct URLs from user input or database values. Encoding those values helps produce valid and predictable URLs.
URL Encoding vs URL Decoding
URL encoding and URL decoding are opposite operations.
URL Encoding
Converts characters into their percent-encoded representation.
URL Decoding
Converts percent-encoded characters back into their original representation.
If you already have an encoded URL and need to read its original values, you need a URL decoder rather than an encoder.

Encoding becomes particularly important when these characters are part of a parameter value rather than part of the URL's actual syntax.
| Original | Encoded | Explanation |
|---|---|---|
| hello world | hello%20world | Space encoded as %20 |
| hello&world | hello%26world | Prevents splitting into multiple params |
| price=100 | price%3D100 | Protects assignment operator in values |
| search?q=test | search%3Fq%3Dtest | Preserves question mark inside values |
| #section | %23section | Prevents browser from jumping to anchor |
| café & tea | caf%C3%A9%20%26%20tea | UTF-8 multi-byte encoding for accents |
| tag: 🚀 | tag%3A%20%F0%9F%9A%80 | 4-byte UTF-8 emoji encoding |
Why Does a Space Become %20?
A space is not represented literally in a standard URL in the same way it appears in ordinary text.
URL encoding represents a space using its percent-encoded value:
For example, hello world becomes hello%20world.
You may also encounter + representing a space in form-encoded data (application/x-www-form-urlencoded). The correct representation depends on the URL or encoding context.
URL Encoding and Special Characters
URLs contain characters with different roles:
?commonly begins a query string.&separates query parameters.=separates a parameter name from its value.#identifies a fragment (anchor).%introduces a percent-encoded sequence.
Example: Handling & in parameter values
Because these characters can have structural meaning, they need to be handled carefully when they occur inside parameter values.
For example, if a parameter contains A&B, the ampersand should generally be encoded as A%26B. This prevents the ampersand from being interpreted as another parameter separator.
Is URL Encoding the Same as Base64 Encoding?
No.
URL encoding and Base64 encoding solve different problems.
URL encoding represents characters using percent-encoded values so data can be safely represented within a URL.
Base64 converts binary or text data into an ASCII string format. It is commonly used for transporting or representing raw binary data, but it is not a replacement for URL encoding.
For URL parameters and URL components, use URL encoding when the goal is to correctly represent characters within a URL.
URL Encoder vs URL Encoding Converter
A URL encoder and a URL encoding converter generally refer to the same type of utility: a tool that converts text or URL components into their percent-encoded representation.
You may see these terms used interchangeably when searching for an online URL encoding tool.
Why Use an Online URL Encoder?
An online URL encoder is useful when you need to quickly encode a URL or parameter without writing code. Lnkeee provides a browser-based URL encoder so you can:
For developers, marketers, students, and anyone working with URLs, an online encoder can be useful for checking how a value will be represented before using it in a link, API request, or application.
Frequently Asked Questions
Common questions about URL encoding, percent encoding, and character handling.
About Lnkeee's URL Encoder
Lnkeee builds practical web utilities designed to make common URL and link-management tasks easier. The URL Encoder is designed for quick, browser-based URL encoding without unnecessary steps. It is part of the Lnkeee toolkit, alongside tools for shortening links, building UTM parameters, and generating QR codes.
For best results, encode the specific URL component or parameter value that requires encoding rather than blindly encoding an entire URL. This helps preserve the structural characters that make up the URL.
