How to Extract Files From a ZIP Archive

Someone sends you a ZIP file, or you download one, and you need the files inside. Extracting (or "unzipping") unpacks the archive back into its original files and folders. Usually it just works — but ZIP files also carry a few risks worth knowing before you open one from an unfamiliar source. This guide explains extraction and how to unzip safely.

What extraction does

A ZIP archive is a compressed container holding one or more files, often organized in folders. Extracting decompresses everything and restores the original files exactly as they were packed, folder structure and all. You get back the real documents, images, or data the archive was made from.

How to extract a ZIP with this tool

1. Open the Zip Extractor tool.
2. Load the ZIP file.
3. View its contents.
4. Extract and download the files.

Everything runs in your browser, so the archive is never uploaded — which is reassuring when you are not fully sure what is inside.

Look before you extract

A ZIP hides its contents until opened, which is exactly why caution helps. Before extracting an archive from an unfamiliar source:

• Preview the file list. Seeing the names and types inside tells you a lot. A ZIP that claims to be photos but contains an executable is a red flag.
• Be wary of executables. Files ending in `.exe`, `.scr`, `.bat`, `.js`, and similar can run code. Never run one from an untrusted ZIP — malware is frequently delivered this way.
• Watch for disguised files. A file named `invoice.pdf.exe` is an executable pretending to be a PDF. Check the real extension.
• Mind deeply nested or oddly huge archives — occasionally ZIPs are crafted to expand into enormous amounts of data.

Being able to inspect the contents before extracting is your safeguard.

If the ZIP is password-protected

Some archives are encrypted and require a password to extract. You will need the password the archive was created with — there is no way around it if the ZIP was properly encrypted. If you encrypted it yourself with Encrypt File, decrypt it with Decrypt File first.

After extracting

Once unpacked, the files are normal again. Not sure what one is? File Inspector identifies it. Need to split a large extracted file? File Splitter.

Privacy and limits

Extraction is fully local — no upload, no file-size cap, nothing stored, offline once loaded. Open the Zip Extractor tool to unpack your archive.
