About This Tool

The Pyinstaller Extractor Online analyzes PyInstaller bundles to reveal embedded files, resources, and packaging metadata. It does not execute embedded code and is suitable for developers, security researchers, and incident responders who need to validate contents before distribution or investigation.
The tool identifies the packaging layout, enumerates embedded items, and provides a structured manifest. It can optionally decompress and export selected resources for offline review, preserving the original binary layout during inspection. This enables quick asset inventory, license verification, and evidence gathering without source decompilation or code execution.
Conceptually, the system scans for PyInstaller-specific packaging markers, isolates embedded archives, and builds a hierarchical view of components such as bootstraps, runtime, and the encoded payload. It emphasizes non-destructive analysis and safe handling of potentially sensitive assets, making it suitable for both development QA and security research use cases. The unique value lies in automated artifact discovery, standardized output, and optional exports that facilitate reproducible analysis across teams.

Frequently Asked Questions

Find Quick Answers

What can I extract from a PyInstaller bundle?

The tool enumerates embedded files and resources, including the PYZ archive contents, bootstrapping components, and metadata. It does not execute code or decompile Python bytecode, but can expose file paths, sizes, and types for verification and auditing.

Is the analysis safe for sensitive bundles?

Yes. Analysis is non-destructive and does not execute embedded payloads. Uploaded artifacts are used to generate a manifest and optional exports; ensure you comply with data ownership and privacy policies for any sensitive data.

Which file types are supported for export?

Exports can include a complete file manifest in JSON and, when enabled, a ZIP archive of extracted resources. Bytecode or proprietary formats are exposed as files with their type and path metadata without executing them.

Can I use this for licensing and compliance checks?

Yes. The manifest lists embedded assets and licenses when present, enabling quick verification of included libraries, licenses, and third-party assets within a PyInstaller bundle.
