## Overview

The URL Encoder/Decoder is a straightforward utility designed to convert special characters into a URL-safe format or revert encoded strings back to their original readable text.

## Inputs

- **Text Input** (text): Enter text to encode/decode...
- **Operation** (select)

## When to use

- When preparing special characters or spaces for inclusion in a web address.
- When you need to interpret a URL-encoded string found in a browser address bar or API response.
- When debugging web requests to ensure parameters are correctly formatted for server transmission.

## How it works

- Paste your text into the input field.
- Select 'Encode' to convert special characters into percent-encoded format.
- Select 'Decode' to transform percent-encoded characters back into standard text.
- Copy the resulting output for use in your application or browser.

## Use cases

- Sanitizing query parameters for web forms.
- Decoding URL-encoded data from API logs for easier reading.
- Formatting file paths or filenames for web-based access.

## Frequently asked questions

### What is URL encoding?

URL encoding converts characters that are not allowed in a URL into a format using the '%' symbol followed by the character's hexadecimal value.

### Why should I encode my URLs?

Encoding ensures that special characters like spaces, symbols, or non-ASCII characters do not break the URL structure or cause errors during transmission.

### Can I decode any string?

You can decode any string that follows standard percent-encoding rules. If the string is not properly encoded, the output may remain unchanged.

### Is this tool secure?

Yes, all processing happens locally in your browser, ensuring your data is not sent to any external server.

### Does this tool support batch processing?

This tool is designed for single-string processing to ensure accuracy and simplicity.
