The URL Encoder & Decoder tool helps you convert unsafe URL characters into a web-safe format and decode encoded URLs back into readable text. It supports percent encoding, UTF-8 characters, query strings, API URLs, and browser-safe URL formatting.

What is URL Encoding?

URL encoding converts reserved or unsafe characters into percent-encoded values. For example, a space becomes %20, and special symbols convert into hexadecimal character triplets. Browsers, servers, APIs, and web applications use URL encoding to keep URLs valid and readable during data transmission. This process follows web standards such as RFC 3986.

How URL Encoding Works
The encoding process converts characters into UTF-8 or ASCII values and then changes them into hexadecimal format. Each encoded value starts with a percent sign (%).

What is a URL Encoder/Decoder?

A URL Encoder/Decoder tool helps users safely convert text and URLs between readable and encoded formats. It improves URL compatibility, data safety, and web interoperability.

URL Encoder

A URL encoder converts unsafe characters into percent-encoded values that browsers and web servers can safely process. It helps create browser-safe URLs for forms, APIs, redirects, and query strings. Developers often encode spaces, symbols, Unicode characters, and special characters before sending data through HTTP GET requests or web applications.

URL Decoder

A URL decoder restores encoded URLs back into normal readable text. It converts percent-encoded values such as %20 or %3A into their original characters. This process helps developers inspect encoded query strings, troubleshoot URLs, and debug web applications more easily.

Privacy and Security

This URL Encoder & Decoder processes data directly in your browser, helping protect privacy and reduce external data exposure. Encoded and decoded URLs are not permanently stored on servers, and users can convert links securely without registration, software installation, or sharing personal information.

Common URL Encoding Mistakes

Common URL encoding mistakes include double encoding already encoded values, failing to decode query parameters before processing, using unsafe or unsupported URL characters, and handling UTF-8 text incorrectly. These errors can lead to broken links, invalid requests and data corruption.
