It automatically detects the input type and provides real-time conversion. Supports parsing escape sequences (such as \n, \x41, \u0041, etc.) for handling special characters. Customizable separators (space, comma, newline, tab, or none) with optional prefixes (0x/0o/0b) and uppercase/lowercase formatting. Features a built-in ASCII character table (0-127) for quick reference. Supports one-click copy, copy as array format, and downloading conversion results. Encode/decode modes can be swapped with one click. All processing is done locally in your browser, ensuring your data is never uploaded.
