or click to browse - works for ZIP files up to 500 MB
Drag your .zip file onto the upload area, or click to browse. Password-protected and AES-encrypted ZIPs work too - you'll be prompted for the password. Files up to 500 MB are handled in the browser via WebAssembly.
Click folders or use the breadcrumb trail to navigate. Use the search bar to find files by name across the whole archive - the original folder structure is fully preserved.
Click any text, code, or image file to open it without extracting - handy for verifying a download contains what you expected before unpacking it.
Grab single files with the download icon, hand-pick items via the checkboxes, or click Extract All as ZIP to repackage everything with a branded README inside.
Working with other formats? Use the Archive Viewer for RAR, 7Z, TAR, GZ, BZ2 and XZ, the dedicated 7Z Viewer, or the GZ Opener for .gz logs. Want to build a ZIP instead of opening one? Use the Archive Creator.
ZIP is the most widely used archive format in the world, supported natively by Windows, macOS, and most Linux distributions. Created by Phil Katz in 1989, the ZIP format combines file compression with archiving, bundling multiple files and folders into a single compressed package. ZIP files use the .zip extension and are recognized by virtually every operating system and application.
The ZIP format supports several compression methods, with DEFLATE being the most common. Modern ZIP files can also include AES encryption for password protection, making them suitable for sharing sensitive files. While Windows and macOS have built-in ZIP support, this online viewer adds features native tools don't offer - inline file preview, search across the whole archive, and selective extraction without unpacking everything.
ZIP prioritizes universal compatibility over maximum compression. 7Z and RAR achieve smaller file sizes but need specific software - open those with the Archive Viewer or the dedicated 7Z Viewer. TAR.GZ is the Unix/Linux equivalent for bundling and compressing - the GZ Opener handles those. For building your own ZIP archives, use the Archive Creator.
ZIP is the most widely supported archive format - Windows, macOS, Linux, iOS, Android. This viewer handles all ZIP variants including ZIPX.

All processing runs in your browser via WebAssembly. Your ZIP files are never uploaded to any server.
Drag your .zip file onto this page and the contents appear in your browser instantly. No WinZip, no 7-Zip, no software at all. The ZIP is read locally using WebAssembly, so it works on any device - including Chromebooks, tablets, phones, and work-locked PCs where you can't install software.
Yes - when you open an encrypted ZIP you'll be prompted for the password before the file list is shown. Once verified, you can browse all contents, preview files, and extract individual items just like an unprotected ZIP. Both legacy ZipCrypto and modern AES-encrypted archives are supported. The password stays in your browser and is never transmitted or stored.
Yes - all processing happens locally in your browser using WebAssembly. Your ZIP files are never uploaded to any server, so there's no risk of data exposure or unauthorized access. When you close the browser tab, all data is cleared from memory automatically. Still concerned? Please contact us and we'll be happy to help!
Yes - click the download icon next to any file to extract just that one entry, perfect when you only need one or two files without unpacking everything. You can also tick multiple files and folders with the checkboxes to bundle a custom selection, or click Extract All as ZIP to repackage everything with the original folder structure and a branded README inside.
Since processing happens in your browser, the practical limit depends on your device's available memory. The viewer handles ZIPs up to 500 MB comfortably on modern devices. Larger archives may still work but parsing speed varies with your device. The file list usually loads quickly even when full extraction takes longer - so you can browse and grab individual files without waiting.
Most common types preview directly in the browser: images (PNG, JPG, GIF, WebP, SVG, BMP, ICO), text files, source code (JS, CSS, HTML, PHP, Python and more), JSON, XML, CSV, and Markdown. Other file types show a download prompt so you can open them with the appropriate application. For specialized previews, see our 200+ file viewers.
For those, use the Archive Viewer which handles RAR, 7Z, TAR, TAR.GZ, GZ, BZ2, XZ, ISO and CAB in addition to ZIP. Or use the dedicated 7Z Viewer for 7-Zip archives and the GZ Opener for GZIP-compressed log files. To build a new ZIP, use the Archive Creator.
