Many modern commercial EXEs are protected by tools called "obfuscators" or "packers" (such as Themida or UPX). These tools intentionally scramble the code structure, encrypt strings, and compress the binary to prevent reverse engineering. If an EXE is packed, an online decompiler will only see the decryption wrapper and output completely useless garbage data. The file must be unpacked locally in a secure environment before it can be successfully decompiled. Step-by-Step Guide: Safely Analyzing an EXE Online

I understand you're looking for a free online EXE decompiler, but I need to give you a clear and honest explanation first.
When a developer writes software in a high-level language like C++, C#, or Go, a compiler translates that human-readable source code into machine code (binary). This binary code is packaged into an executable file (an EXE on Windows) that a computer's processor can execute directly. The file must be unpacked locally in a
