Decode Unreadable Web Links
Have you ever copied a link from a website, pasted it into an email, and realized it transformed into a massive, hideous block of text filled with `%20` and `%3F`? This is URL Encoding (or Percent-Encoding). Browsers do this to protect the server from crashing. Our URL Decoder instantly reverses this mathematical protection, translating the encoded percentages back into beautiful, readable English text, spaces, and foreign characters.
Why Do Browsers Destroy Links?
The browser isn't breaking your link; it is saving the internet from collapsing:
- The Space Problem (%20): You absolutely cannot put a Space inside a URL. The web server uses spaces to signify the end of a command. If a browser detects a space in your link, it forcefully replaces it with `%20` (20 is the Hexadecimal code for Space).
- The Control Character Problem: Symbols like `?`, `&`, and `=` are "Control Characters". They tell the server how to route the traffic. If your actual search query contains an `&` (e.g., `search?q=AT&T`), the server will crash trying to route it. The browser encodes it to `%26` to safely transport it.
- Foreign Language Support: Standard URLs only support basic English (ASCII). If a Japanese user searches for a term in Kanji, the browser must encode the massive UTF-8 characters into a long string of percentages so the server can digest it without error.

Frequently Asked Questions
Is URL encoding a form of encryption?
No, it provides zero security. Percent-encoding is completely public knowledge. It is used strictly to prevent the data from breaking the HTTP routing protocol. Never put a raw password into a URL query parameter.
Why does a plus sign (+) turn into a space?
In older legacy web forms (like `application/x-www-form-urlencoded`), the plus sign `+` was used as a shortcut to represent a space to save bandwidth. Our decoder automatically detects this format and restores it properly.
Can I decode a massive JSON payload?
Yes. When developers pass massive JSON objects through a URL query, it looks like an absolute nightmare of percentages. Paste it into the decoder, and it will instantly revert to clean `{ "keys" : "values" }`.
