JSZip is a JavaScript library for creating, reading, and editing .zip archive files with a simple promise-based API. It works in both browsers (including legacy IE) and Node.js, supporting base64, blob, and other output types.
Use cases
- create zip files in the browser
- read and extract zip archives in javascript
- generate a downloadable zip of multiple files
- edit existing zip archives in node.js
- compress files client-side before upload
- unzip files in a web app
When to choose
- you need zip creation or extraction in JavaScript without native dependencies
- you need broad browser support including older browsers
- you want a simple, well-documented API for zip archives
When to avoid
- you need formats other than zip such as tar, gzip, or 7z
- you need maximum compression performance for large files in a native environment
- you need streaming processing of very large archives
