Frequently Asked Questions about URL Encoder & Decoder
Quick answers to common questions about usage, conversion rules, privacy guarantees, and best practices.
What is URL encoding (percent-encoding)?
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves complete URI structures by leaving protocol and path separators (like :// and /) intact. In contrast, encodeURIComponent encodes all reserved characters, making it suitable for encoding query parameters and query string values.
Can this tool decode percent-encoded URLs back to plain text?
Yes. The tool offers bi-directional operation, decoding percent-encoded characters, hex entities, and plus-encoded spaces back into readable UTF-8 strings.
