What Is ZIP Extract/View?

ZIP Extract/View lets you browse and extract files from ZIP archives directly in your browser. Using the JSZip library, it reads archives client-side and displays a complete file listing with names, sizes, and modification dates. Files and folders are sorted for easy browsing. You can extract and download individual files without extracting the entire archive. All processing happens in your browser — your files are never uploaded to any server.

Why Use ZIP Extract/View?

Browse ZIP contents without extracting everything.
Extract individual files selectively.
Shows file sizes, dates, and folder structure.
Complete privacy — ZIP files stay in your browser.

Technical Guide

ZIP reading is handled by JSZip's loadAsync() function which parses the binary ZIP format from an ArrayBuffer. The library reads the ZIP central directory to build a file listing.

Each entry provides: relative path (name), modification date, compressed and uncompressed sizes, and whether it is a directory. Entries are sorted with directories first, then alphabetically.

File extraction uses JSZip's async() method with 'blob' type to decompress individual files. The resulting Blob is downloaded using a temporary anchor element and object URL.

Note: Encrypted/password-protected ZIP files are not supported by JSZip.
