URL Encoder / Decoder

URL encoding is essential for web developers, API integrations, and anyone sharing data through URLs. Our free online URL encoder/decoder tool lets you instantly convert between safe and readable URL formats without installation or registration.

Why URL Encoding Matters

When you include special characters in URLs—like spaces, ampersands, or accented letters—they can break links or cause security issues. URL encoding converts these characters into percent-encoded format (like %20 for space) that browsers and servers safely interpret. For example, the search query 'hello world' becomes 'hello%20world'. This is critical for query strings, API endpoints, form submissions, and any dynamic URL containing user input.

How to Use the URL Encoder/Decoder

Step 1: Access the tool. Open the URL encoder/decoder in your browser. No downloads, plugins, or account setup needed.

Step 2: Choose your action. Paste your URL, query string, or text into the input field. If your text contains unencoded special characters and you need a safe URL, select 'Encode'. If you have an encoded URL you need to read, select 'Decode'.

Step 3: Get instant results. The tool processes your input immediately. Your converted URL or decoded text appears in the result field. Click 'Copy to Clipboard' to use it anywhere.

Common Use Cases

API requests: Encode query parameters before sending to REST APIs. Example: 'api.example.com?q=machine learning' becomes 'api.example.com?q=machine%20learning'.

Email links: Encode email addresses and names for mailto: links. Example: 'john doe@example.com' becomes 'john%20doe%40example.com'.

Social sharing: Encode URLs with special characters before posting to social media or messaging apps to prevent link breakage.

International domains: Encode non-Latin characters (Chinese, Arabic, Cyrillic) into percent-encoded format for web-safe URLs.

Form submissions: Encode form data before sending through URLs instead of POST requests.

Characters This Tool Handles

The encoder converts 33 special characters including:

• Space ( ) → %20
• Ampersand (&) → %26
• Equal sign (=) → %3D
• Question mark (?) → %3F
• Hash (#) → %23
• Forward slash (/) → %2F
• Plus (+) → %2B
• Non-ASCII characters like é, ñ, ü, 中文, العربية

Pro Tips for URL Encoding

Preserve path structure: When encoding full URLs, encode only query parameters and fragments, not the protocol (http://) or domain slashes.

Batch operations: Encode multiple query strings by running the tool repeatedly—no limits on number of conversions.

Debugging URLs: Use decode mode to understand what an obfuscated URL actually contains before clicking suspicious links.

API documentation: Bookmark this tool when building integrations—handy reference for encoding parameter values quickly.

International content: Always encode non-ASCII characters for reliable cross-platform URL sharing.

Security and Privacy

All encoding and decoding happens in your browser using JavaScript. Your URLs never leave your device, never sent to servers, and nothing is logged or stored. Use this tool confidently with sensitive information.
