Frequently Asked Questions

A ZIP file is a compressed archive format that bundles multiple files and folders into a single file. It reduces file sizes through compression and is widely used for distributing software, sharing documents, and creating backups. ZIP files preserve folder structure and can be password-protected.

Yes. If a ZIP file is password-protected, you'll be prompted to enter the password. All decryption happens in your browser using JavaScript cryptography—the password never leaves your device.

No hard limit exists, but browser memory constraints apply. Files under 500MB work smoothly on most devices. Very large archives (2GB+) may cause performance issues or fail to load depending on available RAM.

Yes. Click any file in the tree view to download it individually. You can also use the 'Extract All' button to download all contents as separate files in a browser-generated ZIP archive.

Currently only ZIP format is supported. RAR, 7Z, TAR, and other formats require different libraries and may be added in future updates based on demand.

No. All processing happens entirely in your browser using the JSZip library. Your files never leave your device, ensuring complete privacy and security. You can even use this tool offline.

For each file, you'll see the full path, uncompressed size, compressed size, compression ratio, last modified date, and CRC32 checksum. This helps verify file integrity and understand space savings.

Yes. The tree view displays the complete folder structure with expand/collapse controls. Navigate through nested directories just like in a file explorer. Folders show file counts and total sizes.

Files that are already compressed (like JPG, PNG, MP4, or other ZIP files) don't compress further. The ZIP format stores them uncompressed to avoid wasting CPU cycles. Text and uncompressed formats often achieve 50-90% compression.

The viewer displays file metadata and allows extraction. For text files, images, or PDFs, extract them first, then use your browser's built-in preview or other ToolsDock viewers like the Image Viewer or PDF Viewer.
