Frequently Asked Questions

What is the difference between encodeURIComponent and encodeURI?+

encodeURIComponent encodes all special characters including /, ?, and &, making it suitable for query parameter values. encodeURI encodes a full URL but preserves structural characters like ://?#.

Why is URL encoding necessary?+

URLs cannot contain certain characters like spaces, non-ASCII characters, or special symbols. URL encoding converts these into percent-encoded (%XX) format for safe transmission.

How are non-ASCII characters encoded?+

Non-ASCII characters are first encoded as UTF-8 bytes, then each byte is converted to %XX format. For example, the character 'é' becomes '%C3%A9'.

Is my data safe?+

Yes, all encoding and decoding happens entirely in your browser. No data is sent to any server.
