Frequently Asked Questions About URL Encode/Decode
What is URL encoding?
URL encoding (percent-encoding) converts characters that are not allowed in URLs into a format that is safe for transmission. Special characters like spaces, &, ?, and # are replaced with % followed by their ASCII hex code (e.g., a space becomes %20).
What characters are encoded in URLs?
Characters that must be encoded include spaces, &, ?, =, #, %, ~, [, ], and non-ASCII characters. Letters, digits, and characters like - _ . ~ are typically left as-is in standard URL encoding.
Does this handle Unicode characters?
Yes. Our tool properly encodes Unicode characters using UTF-8 encoding before percent-encoding, which is the standard approach used by modern web browsers.
