About this Tool
A URL Encoder / Decoder is a tool that converts text into a URL-safe format and vice versa.
URL encoding replaces unsafe characters like spaces, &, ?, =, and / with percent-encoded values (for example, space becomes %20).
URL decoding reverses this process, turning encoded strings back into readable text.
Developers use it when working with query parameters, API requests, web forms, redirects, and any system where data is passed through URLs.
URLs cannot safely contain spaces, symbols, or certain special characters, which is why URL encoding is essential for web development.
Our free URL Encoder / Decoder helps you instantly convert text into URL-safe format and decode encoded URLs back into readable form. It's useful for APIs, query strings, redirects, and web requests where data must be safely transmitted over the internet.

- Click on Encode to convert normal text into URL-safe format
- Click on Decode to convert encoded URLs back into readable text
- Copy the result with a single click for use in your code or browser

FAQs
What is URL encoding?
URL encoding is the process of converting special characters into a percent-encoded format so they can be safely used in URLs. For example, a space becomes %20.
Why do we need URL encoding?
URLs can only contain a limited set of characters. Encoding ensures that special characters like spaces, &, ?, and = do not break the URL structure.
What is URL decoding?
URL decoding is the reverse process of encoding. It converts percent-encoded characters back into their original readable form.
What is the difference between encodeURI and encodeURIComponent?
encodeURI is used for full URLs and preserves URL structure characters, while encodeURIComponent encodes almost all special characters and is used for query parameters.
Where is URL encoding used?
It is used in query strings, API requests, form submissions, redirects, and anywhere data is passed through a URL.
Can URL decoding fail?
Yes, decoding can fail if the input contains invalid percent-encoding. In such cases, the tool will show an error or return invalid input message.
Is my data stored in this tool?
No. All encoding and decoding happens directly in your browser. Nothing is sent to a server or stored anywhere.
