How to use Selective ZIP Extractor

Add the requested files.
Review the options and the displayed queue.
Select Extract Selected, inspect the result, and download the generated ZIP.

What this file tool does

The extractor reads the ZIP directory, rejects unsafe paths, applies your wildcard, and creates a new ZIP containing only matching file bytes.

Open the archive, normalize entry paths, reject traversal patterns, match selected names, and rewrite safe entries.

Encrypted or damaged archives may fail. Repacking selected entries can use substantial memory for large ZIP files.

Supported inputs and limits

The tool works with files exposed through the browser picker. Actual limits depend on available device memory and browser support.

Tips

Frequently asked questions

How do I extract only certain files from a ZIP?

Enter a wildcard such as docs/*.pdf and run the extractor.

Does the extractor block ../ paths?

Yes. Absolute paths, traversal segments, control characters, and unsafe nested names are rejected.

Can I flatten folders while extracting?

Yes. Choose Flatten names; duplicate base names receive a number.

Can this open password-protected ZIP files?

This page does not request a password, so encrypted entries are reported as unsupported.

Are extracted files uploaded anywhere?

No. Archive reading and repacking happen locally in your browser.
