Convert HEX to another file type
To convert your HEX file to another format, you need Arduino_IDE or other Developer software.
Convert a file to HEX
To convert other file formats to the "Firmware Image" file type, you need software like Arduino_IDE or a similar tool.
About HEX files
A .HEX file is most commonly an Intel HEX file, a standard ASCII text format used to convey binary information for programming microcontrollers, EPROMs, and other logic devices. Unlike raw binary files, HEX files use a structured line-by-line format (including checksums and memory addresses) to ensure data integrity during transfer. This makes them the default output for compilers like Arduino IDE, Keil µVision, and MPLAB X. However, this ASCII structure makes the file significantly larger than the actual code and unreadable as a standard executable. Users often convert .HEX to BIN (raw binary) to create a byte-for-byte memory image for specific burning tools, or to ELF for debugging with symbol data. In rare legacy cases, a .hex file may be a BinHex encoded file from early Macintosh systems, which requires decoding to retrieve the original document.
Convert.Guru analyzes your HEX file, detects the exact format, and lets you read the text inside.
If you want to convert HEX file to ASCII, RGB, TEXT, CMYK, INT, RAL, BASE64, BIN, ENC, CRYPT, AES or DES, you can use Arduino_IDE or similar software from the "Microcontroller Firmware Storage" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or ASC files to HEX, try Arduino_IDE or another comparable tool in the "Microcontroller Firmware Storage" category.
The HEX Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HEX converter.
