About ZIP Inspector & Extractor
Overview
ZIP Inspector & Extractor opens ZIP archives locally in your browser so you can review every file before extracting. It summarizes archive size, compression ratio, file types, folders, and the largest entries without uploading your ZIP to a server.
Features
- Browser-only ZIP inspection and extraction for strong privacy
- Uses the File System Access API to save directly into a folder when supported
- Writes a JSON manifest and text tree alongside extracted files
- Searchable file table with compressed size, original size, and compression ratio
- Safe path handling to avoid writing outside the chosen destination
- Lazy-loaded ZIP engine and sequential writes for responsive browser performance
How to Use
- Choose or drag a .zip file into the upload area.
- Review the file list, folder structure, size totals, and extension breakdown.
- Click “Extract to Folder” and choose an empty or existing destination folder when your browser asks.
- The tool writes the extracted files plus zip-details.json and zip-tree.txt into the selected folder.
FAQ
Are ZIP files uploaded anywhere?
No. ZIP files are read by JavaScript inside your browser and extracted directly to a folder you choose. The archive contents are not sent to this website, a cloud service, or any external server.
Why do I need to choose a folder?
Browsers require explicit permission before a web page can write local files. Choosing a folder gives this tool scoped access to create extracted files and detail reports only inside that destination.
What detail files are saved?
The extractor writes zip-details.json with archive statistics and per-file metadata, plus zip-tree.txt with a readable folder tree. These reports help you audit what was extracted later.
Which browsers support folder extraction?
Modern Chromium-based desktop browsers such as Chrome and Edge support folder selection with the File System Access API. Other browsers may still inspect ZIP metadata, but direct folder extraction may be unavailable.
