Choose or drop a file to display its bytes as eight-bit binary groups. Files up to 64 KiB are read in your browser, and the original file stays unchanged.
The output shows each byte in order, including non-printable values. A UTF-8 text file containing only Hi has two bytes: 01001000 01101001. A trailing newline or a byte order mark appears as extra bytes in the result.
Binary is selected by default. You can switch to hexadecimal or decimal bytes to make the output easier to scan. The preview shows at most the first 2,048 bytes, while copying or downloading uses the complete formatted result.
A few useful details for this tool.
No. The converter reads the file locally in your browser. The website makes normal requests to load, but it does not upload the file for conversion.
The preview shows only the first 2,048 bytes for longer files. Download and successful Copy use the complete formatted output.
The limit is 64 KiB, or 65,536 bytes, for one file. The original file is not modified.
