Encoding & Escaping Tools

String Escape / Unescape, Base64 Encoder / Decoder and URL Encoder / Decoder each solve the same underlying problem from a different angle: a string that is valid in one context is malformed or dangerous in another, and the fix is a deterministic transformation that the receiver can reverse.

String Escape / Unescape handles the five characters that break HTML markup, the backslash sequences that terminate JavaScript string literals early, and the percent-encoding that URL parsers expect in query-string values — all in one page, in both directions. Base64 Encoder / Decoder turns arbitrary binary data into the printable ASCII subset that email headers, data URIs and API tokens require. URL Encoder / Decoder applies encodeURIComponent to a single component or encodeURI to a full address. Unicode Code Point Converter and Hex Dump Viewer are queued next, covering the structured inspection problems that live just past the escaping layer.
