Inspect actual package files and create an opening guide.
What do I open first?
Inspect a ZIP’s actual files, readable manifests and static HTML/CSS/JS references. Generate a clickable, standalone guide. Nothing is installed or executed; the archive stays in your browser.
ZIP only: up to 20 MB compressed, 50 MB expanded, 500 entries, 10 MB per entry; readable UTF-8 text up to 2 MB each and 8 MB total. Passwords, ZIP64, symlinks and high-ratio archives are rejected. Binary application formats are classified only by filename; dynamic imports and runtime behavior remain unverified.
How it works
- Review your inputs and the supported scope.
- Set constraints, run the operation and inspect the evidence.
- Reopen downloaded output before using it.
Example & practical use
Enter your own files or measurements; review the computed result and its stated limits.
Limits and help
Bounded ZIP analysis; inference is labeled and package code is not executed.
Your files are yours.
Image and text processing happens in your browser. Your files are not uploaded to our servers.
Troubleshooting
Try the small example on this page first. If it works, check your input format and size limit. Save any needed input before reloading. You do not need to share a file or password to report an issue.
