Extract ZIP Files Online Free — No Software Needed
You can extract ZIP files online free without WinZip, 7-Zip, or any installed application. Drop your ZIP archive into a browser tab, see the full file list, and download only the files you need. No uploads — extraction happens entirely in your browser.
The Problem With Most Unzip Tools
Most online unzip services upload your archive to a remote server, extract it there, then send files back to your browser. That means your data touches infrastructure you do not control — a problem for anything confidential: contracts, source code, personal documents.
The Unzip Online tool works differently. It uses WebAssembly-accelerated JavaScript (fflate) to decompress the archive directly inside your browser tab. The ZIP never leaves your device.
How to Extract a ZIP File Online — Step by Step
- Open the Unzip Online tool.
- Drag your
.zipfile onto the dropzone, or click Browse to select it. - Click Extract Files. The browser decompresses the archive in memory.
- All files appear in a list with their name and uncompressed size. Click Download next to any file to save it individually.

Advanced Tips
Extracting only specific files from a large archive
After extraction, each file has its own Download button. You do not need to download the entire archive — pick just the files you need and ignore the rest. This is especially useful when someone sends you a large ZIP but you only need one or two documents inside.
Using the tool on iOS or Android
Open the tool in Safari or Chrome on your phone, tap the dropzone, and select the ZIP from your Files app. After extraction, tap Download on the files you want to save to your camera roll or local storage. Works on iOS 15+ and Android 10+.
What to do with nested folders in the ZIP
The tool lists each file with its full path (e.g., project/src/main.js). The subdirectory name is preserved in the downloaded filename, so you can see the original folder structure even though files land in your downloads folder individually.
Common Questions
Are my files uploaded anywhere?
No. Decompression runs entirely in your browser tab using JavaScript. Your data never leaves your device at any point.
Is there a maximum file size?
The only limit is your browser's available memory — typically 1–2 GB per tab on a modern desktop. For very large archives on mobile, a desktop browser is more reliable.
Can I create a ZIP as well?
Yes — use the companion ZIP Compressor to bundle multiple files into a new ZIP archive with your choice of compression level.
