What is URL Encoding?
URL encoding (also called percent encoding) converts characters into a format that can be safely transmitted over the internet. Special characters, spaces, and non-ASCII characters are converted to percent-encoded values (e.g., space becomes %20).
How to Use
- Enter or paste the text you want to URL encode
- Click "Encode URL"
- Copy the encoded result for use in URLs or query parameters
Example
Input:
Hello World! How are you?Output:
Hello%20World!%20How%20are%20you%3FCommon Use Cases
- Encoding query parameters in URLs
- Encoding form data for HTTP requests
- Encoding special characters in API calls
- Creating safe URLs with user input
- Encoding search terms for web applications
Characters That Get Encoded
URL encoding converts these characters:
- Spaces → %20
- Special characters (!, @, #, $, %, etc.)
- Non-ASCII characters (accented letters, emojis, etc.)
- Reserved URL characters (?, &, =, /, etc.)
Frequently Asked Questions
Why do I need URL encoding?
URLs can only contain certain characters. URL encoding ensures that special characters, spaces, and international characters are safely transmitted in URLs without breaking the URL structure or causing errors.
What's the difference between URL encoding and Base64?
URL encoding is specifically designed for URLs and only encodes characters that aren't URL-safe. Base64 encodes all data into a different character set. Use URL encoding for query parameters and Base64 for binary data.
Should I encode the entire URL?
No! Only encode the values in query parameters or path segments. Don't encode the protocol (https://), domain, or structural characters like ? and &.
Is my data sent to a server?
No, all encoding happens in your browser. Your data never leaves your device.
