A cross-language ZIP fix

The archive opens.
The filenames make sense.

Older ZIP files may not say which filename encoding they use. Preview the file list, then manually choose Auto, UTF-8, Japanese (CP932), Simplified Chinese (GBK), or Traditional Chinese (Big5) before extracting.

How to use it: choose View contents, open Filename encoding, then select the encoding that makes the names readable. Karuzip does not guess the encoding automatically. Right-click extraction uses Auto. Filename encoding cannot be selected when creating archives.

One tool, six clear jobs

Archive work without the clutter.

Use the main window when you want control, or work directly from File Explorer. The context menu follows the language selected in Karuzip.

EXTRACT

Extract without extra nesting

Karuzip checks the archive structure and chooses a sensible destination. When a name already exists, choose Replace, Skip, or Keep both.

COMPRESS

Create ZIP, 7z and more

Create ZIP, 7z, TAR, GZIP, BZIP2, XZ, or WIM archives. ZIP and 7z can be protected with a password.

VIEW CONTENTS

Preview before extracting

Search and sort archive contents, inspect details, and extract only the files you select.

Check integrity

Check for damage first

Check the archive contents for damage without extracting them. Karuzip reports a clear result when the check finishes.

FILE EXPLORER

Right-click and continue

Extract here, extract to a folder, or compress to ZIP or 7z from the context menu. The Store version uses the Windows 11 first-level menu; the direct-download version uses the classic cascading menu.

TASKS

Queue work in order

Multiple requests run one at a time. Progress shows completed items and estimated time remaining.

Built for real archives

Large lists stay usable.

Karuzip keeps long archive listings responsive with virtual scrolling. Select a folder, a range, or only the filtered results, then extract just what you need.

  • Search and stable sorting by Name, Size, or Modified
  • Item-based progress for archives with many small files
  • Newly created destinations are cleaned up after failure or cancellation; existing folders are never deleted
  • Passwords are not saved to settings, history, or logs

Before you install

Questions, answered plainly.

Karuzip has two distribution routes. Choose the Microsoft Store on Windows 11 for Microsoft-signed installation, or the official installer for Windows 10 and Windows 11.

Is Karuzip free?

Yes. Karuzip is free to use, with no ads, in-app purchases or bundled offers in the current release.

Can Karuzip extract RAR files?

Yes. Karuzip can extract RAR archives, but it does not create RAR archives.

How does Karuzip fix garbled ZIP filenames?

Open the ZIP with View contents, then change Filename encoding to UTF-8, Japanese (CP932), Simplified Chinese (GBK), or Traditional Chinese (Big5) before extracting.

Does Karuzip upload my files?

No. Archive processing stays on your PC. The app has no ads, tracking, or telemetry. This website uses GA4 as described in the Privacy Policy.

Which Windows versions are supported?

The Microsoft Store version is for Windows 11. The 64-bit official installer supports Windows 10 and Windows 11.

Why can Windows show a warning for the official installer?

The direct-download installer is an unsigned beta, so Microsoft Defender SmartScreen may show an “unrecognized app” warning. This is a reputation warning, not a malware detection result. You can verify the published SHA-256 hash, or use the Microsoft-signed Store version on Windows 11.

Extract files without ads, bundles or app telemetry.

Choose the Microsoft Store version for Windows 11, or download the unsigned installer for 64-bit Windows 10 and 11.
