Frequently Asked Questions

What is URL encoding?

URL encoding, also known as percent-encoding, is a method to encode special characters in URLs so they can be safely transmitted over the internet. Special characters are replaced with a "%" followed by two hexadecimal digits representing the character's ASCII value.

When should I use URL encoding?

Use URL encoding when: including special characters in query parameters, passing data in URLs, submitting form data via GET method, creating API endpoints with dynamic parameters, or when dealing with non-ASCII characters like emojis or international text in URLs.

What characters need to be URL encoded?

Characters that must be encoded include: spaces (%20), ampersands (%26), question marks (%3F), equals signs (%3D), plus signs (%2B), percent signs (%25), and all non-ASCII characters. Alphanumeric characters (A-Z, a-z, 0-9) and some symbols (-, _, ., ~) don't need encoding.

What's the difference between encodeURI and encodeURIComponent?

encodeURI is for encoding entire URLs and preserves characters like :, /, ?, &, =, #. encodeURIComponent is for encoding URL components (like query parameters) and encodes almost all characters except alphanumerics. Our tool uses encodeURIComponent/decodeURIComponent for comprehensive encoding.

Can URL encoding handle Unicode and emojis?

Yes, our tool properly handles Unicode characters and emojis using UTF-8 encoding. Characters are first converted to UTF-8 bytes, then each byte is percent-encoded. This ensures proper transmission and display of international text and special symbols in URLs.

What happens if I don't encode URLs properly?

Unencoded URLs can cause: broken links, incorrect data transmission, security vulnerabilities (like XSS attacks), server errors, and browser compatibility issues. Proper encoding ensures URLs work consistently across all browsers, servers, and network systems.

Is my data stored or saved anywhere?

No! All processing happens locally in your browser. We don't store, save, or transmit your data to any servers. Your content remains completely private and secure.

Is this tool completely free?

Yes, 100% free! No registration required, no hidden fees, and no limitations on usage. You can use it as much as you need.
