Safe, instant, and secure URL percent-encoding for web developers.
URL encoding, also known as **Percent-encoding**, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be encoded. For example, a space becomes **%20**.
Our tool uses the standard JavaScript `encodeURIComponent` and `decodeURIComponent` functions to ensure your links are compatible with all modern browsers and servers.
The internet speaks a specific language, and in that language, every character matters. Whether you are a web developer in Karachi fixing broken links, an SEO specialist in London optimizing "slugs" for search engines, or a cybersecurity analyst in New York inspecting suspicious strings, a URL Encoder Decoder is your essential logical utility. Also known as Percent-encoding, this process ensures that data sent via URLs remains intact, secure, and readable by web servers across the globe, regardless of the browser or operating system being used.
Our online syntax solver provides a high-fidelity interface to transform unsafe characters into a web-safe format and back again. By utilizing our computational integrity utility, you can handle spaces, symbols, and non-ASCII characters with 100% precision. This tool is designed for professionals who need to ensure that their tracking parameters (UTM codes), API queries, and website addresses function flawlessly without triggering 404 errors or security blocks.
To provide a high-level technical analysis, our syntax estimator breaks down the components of URL structure and safety:
Certain characters like ?, &, =, and / have special meanings in a URL (reserved). If you want to use them as actual data, they must be encoded. Unreserved characters (A-Z, 0-9, -, _, ., ~) never need encoding.
In the path part of a URL, a space becomes %20. In the query part (after the ?), it can often be represented as a +. Our Numerical Logic Utility handles these nuances automatically to ensure compatibility.
With the rise of non-English websites, encoding is vital for languages like Urdu, Arabic, or Chinese. Our tool converts these beautiful scripts into a format that the backbone of the internet can process without data loss.

Character: [ ] # @ ! $
Encoded: %5B %5D %23 %40 %21 %24
& and ? signs are preserved or converted based on your needs.Email%20News to prevent tracking links from breaking in certain email clients.
In the Development and SEO niche, Google values technical precision, security, and developer-friendly UX. Our Computational Logic Utility stands out by:
%20 will turn it into %2520, which can break your link. Always decode first if you are unsure of the string's state!
| Character | Encoded Value | Common Usage |
|---|---|---|
| Space | %20 | Separating words in titles/slugs. |
| # | %23 | Used for ID anchors in HTML. |
| & | %26 | Separating parameters in query strings. |
| / | %2F | Defining directory structures. |
| @ | %40 | Used in email addresses or user handles. |
$ or #, some browsers or servers might misinterpret the link, leading to broken pages or lost data.
