🔗 URL Encoder – Safe Text Encoding for Web URLs

When working with URLs, certain characters can cause problems if they're not properly encoded. The URL Encoder tool converts text into a format that's safe for use in URLs, query parameters, and form submissions.

This guide explains what URL encoding is, how it works, and walks you through using our free online URL encoder tool to ensure your URLs work correctly.

📘 What Is URL Encoding?

URL encoding, also known as percent-encoding, is a method to convert characters into a format that can be transmitted over the Internet. It works by replacing unsafe ASCII characters with a '%' followed by two hexadecimal digits representing the character's ASCII value. Spaces can be encoded as plus signs (+) or as %20.

For example, the space character is encoded as "%20", the ampersand (&) becomes "%26", and the equals sign (=) becomes "%3D".

⚙️ How the URL Encoder Tool Works

Our URL encoder tool lets you instantly convert any text into a URL-safe format — all right in your browser. It works in real-time and ensures your data stays private by processing everything locally without sending data to any server.

🧩 Key Features

• ⚡ Instant encoding as you type
• 🔐 Client-side only — no data is ever uploaded
• 📋 Copy to clipboard with one click
• 🔄 Support for both full string encoding and query parameter encoding
• 📱 Mobile and desktop-friendly interface

💡 Practical Uses of URL Encoding

• 🔍 Creating valid query parameters for APIs and web requests
• 📝 Encoding form data for POST requests
• 🌐 Making non-ASCII characters work in URLs
• 🔤 Handling special characters in URL paths
• 📊 Creating data URIs with encoded content

For example, if you need to include a space in a URL parameter like search=hello world, you would encode it as search=hello%20world to ensure it works correctly.

✅ Benefits of Using URL Encoding

• ✔️ Prevents URL parsing errors
• ✔️ Makes special characters safe for use in URLs
• ✔️ Ensures consistent behavior across browsers and servers
• ✔️ Supports international characters in URLs

⚠️ Characters That Need URL Encoding

The following characters should always be encoded in URLs:

• ❌ Unsafe characters: spaces, quotation marks, < > % | ^ ~
• ❌ Non-ASCII characters: é, ñ, 漢字, etc.
