Q: What characters need to be URL-encoded?
Characters like spaces, &, =, ?, #, /, and non-ASCII characters (such as Unicode letters and emojis) must be percent-encoded when used in URL components like query parameters and path segments.
Q: What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URI, preserving characters that are valid in a URI (like : / ? # @ etc.). encodeURIComponent encodes individual URI components and will encode those special characters as well. This tool uses encodeURIComponent for maximum safety.
Q: Is URL encoding the same as Base64 encoding?
No. URL encoding (percent-encoding) replaces specific characters with %XX hex codes and is designed for URLs. Base64 encoding converts binary data to a 64-character ASCII alphabet and is used for data transmission. They serve different purposes.
