URL Decoder

Online URL decoder – decode addresses, parameters and IDN domains in one click

The Online URL decoder tool allows you to quickly decode encoded web addresses and display their human-readable version. It supports Standard (urldecode) and Raw (rawurldecode) modes, replaces "+" characters with spaces, supports multiple decoding passes, and handles IDN → UTF-8 conversion for domains containing international characters. In seconds, you will see the complete address components – scheme, host, path, query, and fragment – along with an organized table of parameters. This is the ideal solution for SEO specialists, marketers, developers, and data analysts.

Thanks to the intuitive interface and client-side browser processing, your URL never leaves your device. The tool works fast, securely, and without installation – simply paste the link, click "Decode", and it is ready.

What is URL encoding and decoding

On the web, every URL address must be written in a format compatible with the HTTP protocol. This means that special characters, spaces, and non-ASCII letters must be converted into percent-encoded codes – e.g., "%20" instead of spaces or "%C5%BB" instead of "Ż". This process is known as URL encoding (percent-encoding). Its inverse is URL decoding, which restores the original, readable text.

In practice, you encounter encoded addresses every day – in UTM campaign links, API requests, affiliate links, or search engine results. There are also frequent IDN domains (Internationalized Domain Names) that use national characters, e.g., "żółć.pl" written as "xn--c-uga.pl".

Our tool combines both capabilities: it allows you to decode entire links, parse them into individual components, and automatically translate IDN domains into UTF-8 format. You can thoroughly analyze parameter values and structures without manual text editing.
