Open ZIP Files Online — Browse Locally in Your Browser
Drop a .zip file here or choose one from your device
Standard .zip archives are supported, including Zip64, data descriptors, and password-protected entries.
Your archive stays in your browser. Nothing is uploaded to a server.
What you can explore
Folders, file types, sizes, compression methods, and inline previews appear here after you choose an archive.
Load a ZIP archive to browse folders, search files, preview text and media content, inspect Zip64 metadata, and download individual entries locally.
Open and explore ZIP files in your browser without uploading them. Browse folders, search files, preview text content, and download individual entries locally.
How to open a ZIP file online without uploading
Choose or drag a .zip file into the uploader above. The archive is parsed entirely in your browser using local JavaScript, so you can inspect contents before extracting anything.
Browse ZIP contents locally in your browser
After loading an archive, use the folder tree and file table to explore nested paths, sizes, compression methods, and Zip64 metadata. Search and filter help you find specific files quickly.
Supported file previews and limitations
Preview common text formats (TXT, JSON, CSV, Markdown, HTML, XML, source code), images (PNG, JPG, GIF, WebP, SVG), PDFs, and audio/video files up to 1 MB. JSON is pretty-printed; unknown binary files show a hex dump. HTML is shown as source, not rendered. Password-protected ZIPs can be unlocked locally.
Privacy and security: files never leave your device
ZIP Archive Explorer does not upload your archive to a server for parsing or preview. Processing happens on your device. Risky paths (zip-slip patterns) are flagged so you can review archives safely.
How to extract a single file from a ZIP archive
Select any file in the table or tree, then click Download to save just that entry with its original filename. This is useful when you only need one document from a large archive.
Frequently Asked Questions
Do you upload my ZIP file to a server?
No. ZIP Archive Explorer parses archives locally in your browser. Your files are not sent to our servers for browsing, preview, or download.
Can I preview files inside the ZIP?
Yes. Text formats, JSON (pretty-printed), images, PDFs, and common audio/video files can be previewed up to 1 MB. Binary files without a known type show a hex dump. HTML is shown as escaped source text for safety.
Can I download only one file from the archive?
Yes. Select a file and use the Download action to extract that single entry with its original filename.
Do you support password-protected ZIP files?
Yes. Password-protected archives can be unlocked in your browser. Enter the password to preview or download encrypted entries. ZipCrypto and AES-encrypted ZIPs are supported via zip.js.
What ZIP edge cases do you handle?
The explorer reads Zip64 archives, data-descriptor entries, archive comments, and self-extracting prefixes. It flags risky paths (zip-slip patterns such as ../ segments or absolute paths) and duplicate entry names.
What archive formats are supported?
This tool supports standard .zip files only. Other formats such as .7z, .rar, or .tar.gz are not supported.
Is there a preview size limit?
Previews are capped at 1 MB of decoded content to keep performance predictable. Larger files can still be downloaded.
