Overview

ZIP Manager — Create, Browse, and Secure ZIP Archives in Your Browser

ZIP Manager is a browser-based archive tool with three distinct modes. The Create ZIP panel lets you add multiple files, set an optional password, name the archive, and download it as a standard .zip file. The View ZIP Content panel reads any .zip file and lists every entry with its compressed and uncompressed sizes, letting you open text files and images directly in the browser without extracting the whole archive.

The Encrypt / Decrypt panel takes an existing ZIP and either adds AES encryption with a new password or removes existing encryption so you can work with the plain files. All operations run locally in your browser using the @zip.js/zip.js library. Your files are never sent to a server at any stage of the process.

How to use it
  1. 1Choose a panel: Create ZIP to build a new archive, View ZIP Content to inspect an existing one, or Encrypt / Decrypt to add or remove password protection.
  2. 2In Create ZIP, click Add Files to select one or more local files, optionally enter a ZIP file name and password, then click Download ZIP.
  3. 3In View ZIP Content, upload a .zip file. If it is password-protected, enter the password when prompted to unlock the entry list. Click Open next to any text or image file to preview it inline.
  4. 4In Encrypt / Decrypt, upload a ZIP, choose Encrypt or Decrypt, provide the required passwords, set an output file name, and click the action button to download the processed archive.
Key features
  • Create ZIP archives from multiple files with an optional AES password — all processing runs in the browser.
  • View the full entry list of any ZIP including file sizes, compression ratios, and encryption status without extracting.
  • Preview text files (TXT, JSON, CSV, HTML, JS, CSS, YAML, and more) and images (PNG, JPG, GIF, WebP, SVG) directly inside the page.
  • Unlock password-protected ZIP files to browse and open individual entries without a native app.
  • Add encryption to an unprotected ZIP or remove encryption from a protected ZIP and download the result.
  • Progress indicators show real-time completion percentage during compression and decompression.
  • Zero server involvement — the zip.js library handles all reading and writing locally in your browser tab.

Frequently asked questions

Are my files uploaded to a server?
No. Every operation — reading, writing, encrypting, and decrypting — happens inside your browser using the @zip.js/zip.js library. Files are processed in memory and downloaded directly to your device.
What encryption standard is used for password-protected ZIPs?
The tool uses AES-256 encryption via the zip.js library, the same algorithm supported by modern ZIP tools and compatible with standard archive software.
Can I open ZIP files that were created by other software?
Yes, as long as the ZIP uses standard deflate compression. Password-protected archives are supported when AES encryption was used. Some legacy ZipCrypto-protected archives may not open correctly.
Is there a file size limit?
There is no fixed limit imposed by the tool. Practical limits depend on your browser and available device memory. Very large archives (multiple gigabytes) may be slow or cause the browser to run low on memory.
