🔗 URL Encoder / Decoder Tool

The URL Encoder / Decoder is a free, user-friendly online tool designed for developers, marketers, and anyone who needs to convert URLs between encoded and decoded formats. Whether you’re preparing URLs for web development, troubleshooting, or simply making links more readable, this tool streamlines the process with a simple interface and powerful features.

What is URL Encoding and Decoding?

URL Encoding (also known as percent-encoding) transforms special characters in a URL into a format that can be safely transmitted over the internet. For example, spaces become %20, and non-ASCII characters are converted to a URL-safe format.
URL Decoding reverses this process, converting encoded characters back to their original, human-readable form.

How Does the Tool Work?

Input Text: Enter or paste the text or URL you want to encode or decode in the input box. The tool supports both plain text and full URLs.
Encode URL: Click the Encode URL button to convert your input into a URL-safe format. All special characters, spaces, and non-ASCII symbols will be encoded.
Decode URL: Click the Decode URL button to transform encoded URLs or strings back to their original, readable form.
Auto-Detect on Paste: When enabled, the tool automatically detects whether your pasted content should be encoded or decoded, saving you time and effort.
Output Text: The result appears in the output box, ready to copy or use as needed.
Copy & Clear: Easily copy the output to your clipboard or clear all fields with a single click.

FAQs

Q: What is URL encoding?

URL encoding replaces unsafe ASCII characters with a “%” followed by two hexadecimal digits. It ensures URLs are transmitted correctly over the internet.

Q: When should I use URL encoding?

Use encoding when your URL contains spaces, special characters, or non-English letters, especially when embedding URLs in HTML, APIs, or query strings.

Q: What does URL decoding do?

Decoding converts encoded characters (like %20) back to their original form (like a space), making URLs readable again.

Q: Is my data safe? Does this tool send my input to a server?

No, all encoding and decoding is done in your browser. Your data never leaves your device.

Q: What is the auto-detect feature?

When enabled, the tool automatically decides whether to encode or decode based on your pasted content—encoding if it contains spaces, decoding if it contains percent signs (%).
