Encoding & Conversion

URL Encode/Decode converts URL components and values locally with percent encoding using encodeURIComponent/decodeURIComponent semantics for spaces, reserved characters, UTF-8 text, emoji, query values, and path segment data.

URL Parser parses a single URL or relative path locally into protocol, credentials, host, port, path, hash, and query parameter rows, lets you edit them, and previews the rebuilt URL.

Base64 Encode/Decode handles UTF-8 text, Base64URL and MIME-wrapped output, plus image workflows for Data URLs, raw Base64, local preview, and image download.

JSON Escape/Unescape converts raw text to JSON-safe string content and decodes escaped JSON string content back to readable text locally.

Escape HTML special characters to entities, or unescape named, decimal, and hex character references locally for tag display and code examples.

Convert text and emoji to Unicode code points, decode U+, 0x, simple \u, or decimal tokens, and inspect UTF-8 bytes, UTF-16 units, and surrogate pairs locally.

Unicode Normalizer converts text between NFC, NFD, NFKC, and NFKD forms and removes combining marks locally.

ASCII Converter turns text into decimal ASCII code tokens, decodes decimal, 0x, 0b, and 0o tokens, and shows decimal, hex, binary, octal, and control-character details locally.

Base converter for non-negative binary, octal, decimal, and hexadecimal integers with BigInt precision, matching-field 0b/0o/0x input tolerance, linked updates, and plain-value copy.
