ZIP File Viewer

Before extracting an archive, it is useful to know what is inside it: how many files, what they are called, and whether the archive looks like what you expected. This viewer reads the central directory of a ZIP file, which is the index every standard archive carries at its end, and lists the file names it finds.

You can upload a ZIP file of your own, or press the sample button to see the viewer work on an archive built on the spot. Both paths use the same central-directory parser, so the sample proves the listing logic while the upload path applies it to your real file.

Quick Answer: List every file inside a ZIP archive by reading its central directory.

Best Practices and Tips

Double-check your input before running the tool, since the output is only as good as what you enter.
Keep a copy of the original input until you have confirmed the result works.
Check the file list before extracting an archive from an unknown source.
A ZIP with no central directory is damaged and may not list correctly.
File names in the list are exactly as stored in the archive.

Common Mistakes to Avoid

Running the tool on incomplete input and trusting the first result without a glance.
Forgetting to save or copy the output before closing the tab.
Assuming the viewer extracts files; it only lists what is inside.
Uploading a file that is not a ZIP and expecting a file list.

Frequently Asked Questions

What does the ZIP File Viewer do?

The ZIP File Viewer takes a ZIP archive and turns it into the list of file names stored inside it, right in your browser. You do not need to install anything or create an account, and the result is ready in seconds. It is built for everyday jobs where you want a quick, reliable answer without opening a heavy desktop program or uploading your files anywhere.

Is my input private when I use this tool?

Yes. Everything you type, paste, or upload is processed locally in your own browser tab, so it never travels to a server run by this site. The only exception is a feature that explicitly needs a device, such as a camera or microphone, and even then the media stays on your device. Closing the tab ends the session, and nothing about your input is stored on the site.

What should I do if the result looks wrong?

First, check the input for typos, missing values, or an unsupported format, because most unexpected results come from the input rather than the tool. Try a small, simple example you can verify by hand, then compare it with the tool output. If the simple case works and the real case does not, the difference usually points to the part of the input that needs fixing.

Does the viewer extract my files?

No. It only reads the archive index and lists the names. Nothing is extracted or saved, which makes it a safe first look at an archive you have not opened before.

Why does the sample button exist?

It builds a small ZIP on the spot and runs the same parser over it, so you can confirm the listing works even before choosing a file of your own.

Can I use this tool on a mobile phone?

Yes. The tool is built with the same responsive layout as the rest of the site, so controls, inputs, and results adapt to a phone screen. Buttons are large enough to tap comfortably, text fields accept mobile keyboards, and results wrap instead of overflowing. If a feature needs a device capability, such as a camera, the tool will say so on that device rather than failing silently.
