Frequently Asked Questions

What is URL encoding?

URL encoding converts special characters into a format that can be safely transmitted in URLs. For example, spaces become %20 and & becomes %26. This ensures URLs are valid and data is preserved.

When do I need to encode a URL?

You need to encode URLs when they contain special characters like spaces, ampersands, question marks, hashes, or non-ASCII characters. This is common when passing query parameters or constructing API requests.

What is the difference between encodeURIComponent and encodeURI?

encodeURIComponent encodes a URI component by escaping most special characters. encodeURI is used for full URIs and does not encode characters that have special meaning like /, ?, &, #.

Is my text uploaded to a server?

No. All processing happens entirely in your browser. Your text never leaves your device.
