Frequently Asked Questions

Why do URLs need to be encoded?▾

URLs can only contain certain ASCII characters. Special characters like spaces, ampersands, and non-Latin characters must be percent-encoded (e.g., space becomes %20) to be safely transmitted in URLs without breaking the address.

What is the difference between encodeURI and encodeURIComponent?▾

encodeURI encodes a full URL but preserves characters like :, /, and ? that are part of URL structure. encodeURIComponent encodes everything including those characters, making it suitable for encoding individual query parameter values.
