Decompile Node.js 16 .jsc Files
Node.js 16 runs on the V8 9.x line. JSC Decompiler reads the V8 build straight from the bytecode header and turns compiled .jsc files back into readable JavaScript — no matching runtime required.
Bytecode fingerprint
Every .jsc file opens with a 4-byte little-endian magic header that identifies the V8 code-cache format. Node.js 16 files sit on the V8 9.x line, paired with Electron 17 (V8 9.x).

Upload at jscdecompiler.com
Drag and drop your Node.js 16 .jsc file into the web app. Nothing to install.
Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 9.x deserializer automatically — you never pick a version by hand.

Node.js 16 version notes
- Node 16 shipped the V8 9.x line (9.0 through 9.4) and was the first Node LTS to include the Sparkplug baseline compiler (V8 9.1).
- Node 16 and Electron 17 share the V8 9.x line, so their code caches use the same bytecode format family.
- Some Node 16 builds carry the 0xC0DE0562 magic also seen on early Node 18, marking the 9.x→10.x transition; the decompiler disambiguates from the full header.
