# URL Encoder/Decoder — Documentation & FAQ

Documentation for [URL Encoder/Decoder](https://www.razi.pro/tools/url-encoder) — Encode or decode URLs, query strings, and special characters accurately.

## Quick start

Paste text to URL-encode special characters, or decode a percent-encoded string back to plain text.

## Frequently asked questions

### How do I URL encode a string?

Paste your text or URL into the input field and click 'Encode'. Special characters will be converted to their percent-encoded equivalents (e.g., space becomes %20).

### What is URL encoding?

URL encoding (percent-encoding) replaces unsafe characters in URLs with a '%' followed by their hexadecimal value. This ensures URLs are valid and can be transmitted correctly across the internet.

### When do I need to URL encode?

URL encode when passing special characters in query parameters, form data, or API requests. Characters like spaces, ampersands (&), equals signs (=), and non-ASCII characters must be encoded.
