What is a URL Encoder / Decoder?
A url encoder decoder is a tool that helps you convert URLs and text into a safe, web-compatible format and back again.
Web browsers and servers only accept certain characters in a URL. Characters like spaces, ampersands, and question marks can break a link or cause errors. URL encoding replaces these special characters with a percent sign followed by two hex digits. This is also called percent encoding.
For example, a space becomes %20 and an ampersand becomes %26. This makes your URL readable by any browser or server.
Decoding works the other way. It takes an encoded URL and converts it back to plain, readable text. This is useful when you receive a URL from an API, a form submission, or a web log and need to understand what it contains.
Our url encoding tool supports both modes. You can encode a plain URL or decode an encoded one in just a few clicks.
How to Encode or Decode a URL
Step 1: Paste your text or URL. Copy your URL or plain text and paste it into the input box. The tool supports multi-line input.
Step 2: Select your mode. Choose either Encode or Decode based on what you need. You can switch between the two at any time.
Step 3: Convert your input. Click the Encode or Decode button. You can also enable real-time auto conversion so the result updates as you type.
Step 4: Copy or download the result. Click the Copy button to grab your result instantly. You can also download the output as a .txt file for later use.
Why Use a URL Encoder / Decoder?
- Handle special characters safely. Spaces, symbols, and non-ASCII characters can break URLs. Encoding fixes that automatically.
- Improve URL compatibility. Encoded URLs work correctly across all browsers, servers, and APIs without errors.
- Debug API responses. When you receive encoded data from an API, our decode url online tool lets you read it in plain text instantly.
- Build query strings. Developers use a url encoder to format query parameters correctly before sending requests.
- Inspect form submissions. Encoded form data is easier to read once decoded. This helps with testing and debugging web forms.
- Fast and accurate. The tool processes your input immediately with no delays or errors.
- No account required. You can encode url online or decode url online without creating an account or sharing any data.

Frequently Asked Questions
What is URL encoding?
URL encoding is the process of converting special characters in a URL into a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and slashes are replaced with a percent sign and a two-character hex code. This is why it is also called percent encoding.
Why do I need to encode a URL?
Some characters have special meanings in URLs and can cause errors if used directly. For example, a space in a URL can break a link or redirect you to the wrong page. Our url encoder decoder replaces those characters with safe equivalents so your URL works correctly everywhere.
What is the difference between encoding and decoding?
Encoding converts plain text or a raw URL into a percent-encoded format that browsers and servers can read safely. Decoding is the reverse. It takes an encoded URL and converts it back into readable plain text. Both modes are available in this url encoder decoder tool.
Is it safe to use this tool?
Yes. All processing happens directly in your browser. Your data is never sent to any server or stored anywhere. You can encode url online or decode url online with complete privacy.
Who uses a URL encoder decoder?
Developers use it to format query strings and API parameters. Testers use it to inspect form submissions and web logs. Anyone who works with links, web data, or APIs will find this percent encoding tool helpful in their daily workflow.
Can I decode a URL that was encoded by another tool?
Yes. Standard URL encoding follows the same rules across all tools. As long as the input uses percent encoding, our url converter will decode it correctly into readable text.
