How to unzip ZIP files online
Upload a ZIP archive
Choose a .zip file from your device. The archive is processed locally in the browser rather than uploaded to a server.
Preview the ZIP contents
Click Preview ZIP to view the folder tree, search files, inspect file sizes, and open supported file previews. For preview only workflows, the ZIP file viewer online on the homepage is built for inspection without extraction.
Extract the ZIP file
Click Unzip to extract the archive in browser memory. Progress shows the current file and extraction percentage.
Download extracted files
After extraction, click Download All Files to save separate extracted items. You can also download one selected file.
Why use a browser ZIP extractor?
Private local processing
Your ZIP file stays on your device because this online ZIP extractor does not need a backend upload to work.
No software installation
A free unzip tool online is useful when you are on a shared computer, a new device, or a browser-only workflow.
Preview before extraction
You can check folder structure, file names, and supported preview files before you extract the archive.
Supported extraction workflow
Files you can preview
Text, code, JSON, CSV, image, PDF, audio, and video files can be previewed when your browser supports the format.
Files you can extract
Most non-encrypted ZIP entries can be extracted. Unsupported preview types can still be downloaded after extraction.
Password protected ZIP files
Password protected ZIP files are not supported yet, and the tool will show a clear message if encrypted content is detected.
Unzip Online FAQ
What happens after I click Unzip?+
The tool reads the archive entries in browser memory, extracts the files locally, and then enables download buttons for the extracted items.
How does Download All Files save extracted items?+
Download All Files saves separate files through the browser. When folder nesting cannot be preserved by the browser, nested path names are added to file names.
What should I do if my browser blocks multiple downloads?+
Allow multiple downloads for the site when your browser asks. The tool downloads extracted items separately, so browser download protection may request confirmation.
Can I download one extracted file instead of every file?+
Yes. Select an entry from the ZIP tree and use Download Selected File to save only that item after the archive has been read locally.
What should I do if ZIP extraction fails?+
Try another copy of the archive if the file is damaged. Corrupted ZIP files, unsupported encryption, or incomplete downloads can prevent browser extraction.
