Compiler:

The compiler is computer software that converts programming language into machine code. It checks the entire program at a time and gives the error if there is any error. It generates a separate file after the program is compiled.

Interpreter:

The interpreter converts the bytecode into the machine-understandable code line by line. If it finds that there is an error in any line then it gives the error at that line without executing the remaining code. It does not generate a separate file after the program is interpreted.
