📖 Understanding ZIP File Extraction
ZIP files are compressed archives that bundle multiple files and folders into a single, portable container. When you extract or "unzip" a ZIP file, you're reversing the compression process to restore the original files to their full, usable form. This process is essential for accessing content that has been shared, downloaded, or backed up in ZIP format.
The ZIP format uses the DEFLATE compression algorithm to reduce file sizes. During extraction, this compressed data is decompressed and reconstructed into the original files. The ZIP archive also stores metadata including file names, folder structure, timestamps, and file attributes, all of which are restored during extraction.
Our online ZIP extractor uses the JSZip library to read and decompress ZIP files directly in your web browser. This client-side approach means your ZIP files never leave your device - they're processed locally using JavaScript. This ensures complete privacy and security, making it safe to extract sensitive documents, personal photos, or confidential business files.
One of the key advantages of our tool is the ability to preview archive contents before extraction. You can see all files and folders, their sizes, and types, then choose to download individual files or extract everything at once. This selective extraction saves time and bandwidth when you only need specific files from a large archive.
