在瀏覽器本機解壓縮檔案
檔案只會在你的瀏覽器本機處理,不會上傳到我們的伺服器。
將一個壓縮檔拖到這裡
支援 ZIP、7Z、RAR、TAR、GZ、TGZ、ISO、CAB、JAR、APK、Office 檔案和 EPUB 等常見格式。自解壓 EXE 只有在可識別壓縮資料時才支援。

How it works
Three steps, all in your browser. No installs, no uploads, no waiting on a server.
1Add your archive
Drag and drop a ZIP, 7Z, RAR or other archive onto the page, or click to choose a file from your device.
2Extract locally
UnzipIt unpacks the archive on your device using a WebAssembly engine running in a Web Worker. Your files never leave your browser.
3Save your files
Download individual files, or save the whole extraction straight into a folder you choose (on supported browsers).
Supported archive formats
Open and extract a wide range of common archive formats — all locally in your browser.
- ZIP
- 7Z
- RAR
- TAR
- GZ
- TGZ
- BZ2
- XZ
- ZST
- CAB
- ISO
- JAR
- APK
- EPUB
Self-extracting EXE files work only when the embedded archive data can be identified. Many Office documents and EPUB files are also supported because they are ZIP-based.
