Unzip Files Online
Open a ZIP file, preview its contents, and extract safe files locally in your browser. Nothing is uploaded to our servers.
Drop a ZIP file here
Extract ZIP archives locally with no upload.
Supports standard .zip files. Password-protected ZIP files are not supported yet.
Select fileExtract ZIP files without uploading them
AI Toolbox reads your ZIP file with browser JavaScript and lists the archive contents locally. You can preview filenames and sizes, extract documents, images, folders, code packages, and other files, then download individual items or trigger downloads for every extracted file while the archive stays on your device.
Choose a ZIP file
Drag in a .zip archive or select one from your device.
Extract locally
The browser reads the archive and safely skips traversal paths.
Download files
Download individual extracted files or start downloads for all files.
No upload required
The ZIP archive is processed in your browser, not on a server, so private documents and source files do not need to leave your device.
Safe path handling
Entries with ../ traversal paths, absolute paths, or unsafe filenames are skipped to reduce zip-slip risk before download.
Fast file list
See nested folders, filenames, and file sizes before downloading anything from the archive.
Free and simple
No account, watermark, install, extension, or paywall for normal ZIP extraction.
Download one file or all files
Pick a single extracted file when you only need one asset, or use Download all to save every safe file in the ZIP.
Works for common ZIP archives
Open ZIP packages from email attachments, design exports, website backups, classroom downloads, and developer bundles. Very large archives depend on your browser and device memory.
Check an attachment before saving
Inspect the files inside a ZIP download and pull out only the documents or images you actually need.
Open shared project packages
Extract folders from client handoffs, website assets, design exports, code samples, and coursework without installing desktop software.
Use a locked-down device
When you cannot install WinZip, 7-Zip, or another archive app, use a modern browser to extract safe ZIP files locally.
Documents and PDFs
Pull invoices, reports, contracts, spreadsheets, and PDF files out of a ZIP attachment without opening a desktop app.
Images and design assets
Open JPG, PNG, SVG, and exported design files from a shared archive, then download just the assets you need.
Website and project folders
Browse nested folders from website backups, static site exports, and client handoffs, then save the files locally.
Code and text files
Extract source code, config files, JSON, CSV, and plain-text files from developer bundles and coursework downloads.
ZIP input support
Use standard .zip archives. The tool is designed for regular ZIP files; encrypted, password-protected, multi-part, or corrupted archives may fail with a clear error. Very large archives depend on your device memory.
Extracted file downloads
Downloaded files keep their safe relative names where the browser allows it. Unsafe paths are skipped, and folder structure is shown in the file list for easy review.
Best for quick ZIP extraction
Use this online unzip tool when you need to open a normal ZIP file quickly, especially on a shared, school, work, or mobile device.
Best for privacy-sensitive files
Unlike server-side unzip websites, this page does not upload the archive for extraction. Processing happens in browser memory.
When to use a desktop app
Use 7-Zip, WinZip, macOS Archive Utility, or another desktop app for password-protected archives, multi-part archives, very large backups, or advanced compression formats.
Files stay in your browser
The ZIP is read in browser memory with JavaScript. Nothing is uploaded to a server, so sensitive documents and source code never leave your device.
Unsafe paths are skipped
Entries with ../ traversal paths or absolute paths are skipped to reduce zip-slip risk, so a malicious archive cannot write outside your chosen download location.
Why some archives fail
Password-protected, encrypted, multi-part, or corrupted ZIP files can fail to extract. The tool shows a clear error instead of guessing at locked or damaged data.
When a desktop app is better
For encrypted archives, RAR or 7z formats, multi-gigabyte backups, or batch folder restores, a desktop tool such as 7-Zip or WinZip is the better fit.
01Are my ZIP files uploaded?+
No. The ZIP file is read locally in your browser and never sent to AI Toolbox servers.
02Can it open password-protected ZIP files?+
Not yet. Encrypted or password-protected archives may fail to extract.
03What is the file size limit?+
There is no fixed file size limit. Because extraction runs in your browser, very large ZIP files depend on your device memory and browser performance.
04Can I download a whole folder at once?+
Browsers restrict folder downloads, so the tool starts downloads for extracted files instead.
05Does it work on mobile?+
Yes for small ZIP files, though large archives work better on desktop browsers.
06Can I preview filenames before downloading?+
Yes. After extraction, the tool shows the safe file list and sizes so you can decide which files to download.
07Does it preserve folders inside the ZIP?+
The file list shows nested paths from the archive. Browser downloads are still controlled by your browser, so folder saving behavior can vary by device.
08Is this the same as WinZip or 7-Zip?+
It covers quick browser-based ZIP extraction. Use a full desktop archive app for encrypted archives, multi-part archives, RAR/7z files, or very large backups.
09Is it safe to open a ZIP file online here?+
Yes. Because extraction happens locally in your browser, the archive is never uploaded, and the tool skips entries with unsafe traversal paths to lower zip-slip risk.
10What types of files can I extract?+
Any regular files inside a standard ZIP — documents, PDFs, images, design exports, website folders, code, and text files. Preview the list, then download individual items or all files.
Open your ZIP file privately
Choose a ZIP archive and extract files locally in seconds.
Unzip files freeThis tool runs client-side. Your browser reads the archive in memory; AI Toolbox does not upload or store your files.
