The most standard tool for working with UF2 files is uf2conv.py , provided by Microsoft and often maintained in repositories like makerdiary/uf2utils . Step 1: Install Required Tools
: Most professionals use Ghidra or IDA Pro . You can load the unpacked .bin file, specify the base address (typically 0x10000000 for RP2040 flash), and select the ARM Little-endian architecture to see the assembly or pseudo-C code .

Once you have extracted the raw binary from the UF2 file, the real reverse engineering begins. The extracted your_firmware.bin file is the machine code that runs on the target microcontroller. You must now load this raw binary into a disassembler or decompiler to analyze it. uf2 decompiler

Understanding UF2 Decompilers: How to Reverse Engineer Firmware The most standard tool for working with UF2 files is uf2conv
Until then, the two-step process of "extract then disassemble" remains the standard. A dedicated "UF2 decompiler" tool does not exist because the format itself is just a simple delivery container. The real complexity, and the real art of reverse engineering, begins after you have extracted that raw binary and unleashed Ghidra or IDA Pro upon it.
To decompile the extracted binary, you must know the target processor architecture. UF2 files are widely used across various platforms, including: Summary Table: Solid Tools for the Job uf2conv
Technically, you don't "decompile" a UF2 file directly. Decompilation is a two-step process:
Before we can decompile, we must extract the binary image. The logic is straightforward:
