Extract, compress, convert documents to PDF and convert images — four jobs in one app.
Runs offline, so the files you work with never leave your computer.
Windows 10 / 11 (64-bit) · .NET Runtime required · No account needed
The free version is fully functional — no locked formats, no locked encrypted archives, no ads.
Supports zip, rar, 7z, tar, and compound formats such as tar.gz / tar.bz2 / tar.xz. Formats are detected from file headers, so a renamed archive still opens correctly.
No extra softwarePack into ZIP / tar.gz / tar.bz2 / TAR / gz with adjustable compression. Works with multiple files and whole folders, subfolders included.
No extra softwareConvert Word, Excel, PowerPoint and ODF documents to PDF, or to txt / html / csv and more. Conversion uses the office suite already installed on your PC.
Requires Office or LibreOfficeConvert between PNG, JPG, BMP, GIF and TIFF with adjustable quality and size, and combine several images into one multi-page PDF.
No extra softwareThese are not filler for a feature list — they are situations you really run into.
Right-click an archive in File Explorer and extract it with UnZipTool without opening the app first. UnZipTool is also added to the "Open with" list, but never changes what a double-click does.
Point it at a folder and it will unpack new archives on the schedule you set — handy for keeping a downloads folder tidy. It runs through Windows Task Scheduler, so it still works when the app is closed.
Off by default — enable it in SettingsSearch by file name inside an archive with thousands of entries, and double-click to preview a file without extracting anything. Select just the files you want instead of unpacking the whole thing.
Opens ZipCrypto and AES-256 encrypted zip files, plus encrypted 7z. Enter the password once and it is reused for the rest of the session.
File name encoding (GBK / UTF-8) is detected automatically, so older archives do not unpack into a pile of garbled names — a long-standing problem with many tools.
Light, dark or follow-system themes; Simplified Chinese, Traditional Chinese and English interfaces. Switching takes effect immediately — no restart.
These are not slogans but design decisions — and you can verify every one of them yourself.
The app contains no network code at all. Unplug your network cable and every file operation still works — try it.
No usage analytics, no crash reports, no reading device information. There are no accounts and nothing to sign up for.
Archives are written to a temporary file and renamed only on success, so cancelling or failing never leaves a corrupt half-written archive.
Conversion checks what your document type can actually become, so impossible combinations are not offered — instead of letting you click and then fail.
The free version can be used indefinitely. Buy the full version only when you need the size limits lifted.

The app itself is only 4.1 MB. You need to install the .NET Runtime once before first use.
This feature needs Microsoft Office or LibreOffice installed on your PC. After installing, click "Detect again" in the app — no restart needed.
The other three features (extract, compress, image conversion) need no extra software.
No. The app contains no network code and your files stay on your machine. Every file operation works with the network disconnected — you can verify it yourself.
Archive tools read and write many files, which triggers heuristic false positives. Add it to your allow list, or upload the file to VirusTotal to double-check.
The license key is bound to a machine identifier. Replacing the motherboard or reinstalling Windows may change it — contact the issuer to have it reissued. Save your key before deactivating.
Email the issuer with the plan you want and your machine code (shown in the app's activation window). We will reply with payment details and send your license key.
