QUICK ANSWER
Is it possible to convert HEX to JPG?
No - not a direct conversion.

A .hex file holds machine-code bytes for a microcontroller, not photographic data. Any tool claiming to produce a .jpg from a .hex would generate either a meaningless corrupt image or simply rename the file, which no image viewer will open - there is no JPEG header inside.

Why convert HEX to JPG?

Intel HEX is a plain-text format encoding compiled firmware as ASCII records - opcodes and data addresses for the target processor, not pixels. A JPEG is a lossy-compressed raster image storing photographic pixel data. The format mismatch is total: there is no image inside a .hex file that any converter could extract or produce.

How to convert HEX to JPG

Arduino IDE FREE

Flash the .hex to the target microcontroller using the Arduino IDE - this is the intended use of an Intel HEX file, not image conversion.

avr-objcopy OPEN-SOURCE

Convert to a flat binary with avr-objcopy -I ihex -O binary in.hex out.bin to get the raw firmware bytes - the only standard and useful conversion from Intel HEX.

.HEX Intel HEX File

A .hex file is an Intel HEX file: compiled firmware for a microcontroller such as an Arduino, AVR, or PIC chip, stored as plain-text records. You don't run it on a PC - you flash it to the…

A JPG (also .jpeg) is a compressed photo or image in the JPEG format, standardized in 1992. Every operating system opens it natively - double-click and Windows Photos, macOS Preview, or…

Quality & what to watch

  • Intel HEX files start with : characters - the ASCII records contain no image data whatsoever.
  • Renaming a .hex to .jpg changes only the label; an image viewer will reject the file because there is no JPEG header (FF D8 FF).
  • The only genuinely useful conversion from Intel HEX is to a flat binary .bin image using avr-objcopy or SRecord.

Frequently asked questions

Can I rename a .hex file to .jpg?
No - renaming changes only the label; the file has no JPEG header and will be rejected by any image viewer.
What is actually inside a .hex file?
Plain-text ASCII records beginning with :, each encoding address, data bytes, and a checksum for microcontroller program memory - not image data.
Is there any useful conversion from a .hex file?
Yes - convert to a flat binary .bin with avr-objcopy -I ihex -O binary in.hex out.bin to strip the ASCII framing and get the raw firmware bytes.
