Cómo usar: Unzip Files Online

  1. Drop a .zip file on the box or click it to choose one.
  2. Browse the list of files with their sizes.
  3. Click Preview to view text and image files inline.
  4. Click Download next to any file to save it.

Extract ZIP files without software

Desktop systems can open ZIP files natively, but not every device makes it easy — Chromebooks, locked-down work computers, tablets and phones often need an app. This tool reads the archive directly in your browser, lists every entry and lets you save individual files.

Private by design

The archive is read with JavaScript on your device. It is never uploaded, so you can safely open archives with contracts, invoices, source code or customer data. It also works offline once the page has loaded.

Files that are secretly ZIPs

Many modern file formats are ZIP archives with a different extension. Opening them here shows their internal structure:

ExtensionWhat is inside
.docx, .xlsx, .pptxOffice Open XML: document.xml, sheets, embedded images in media/
.epubXHTML chapters, CSS, cover image
.jar, .apkJava classes, manifest, resources
.whl, .nupkg, .xpiPython, .NET and Firefox packages

This is a quick way to pull all images out of a Word document or PowerPoint deck: open the file and download the items in the media folder.

What is not supported

  • Password-protected ZIPs — encryption is not supported; you will see a clear message.
  • RAR, 7z and tar.gz — these are different formats. A .gz file can be decompressed with the gzip tool.
  • Very large archives — the whole archive is held in memory, so multi-gigabyte files may not open on phones.

  • Brotli Compress & Decompress — Compress text or files with Brotli at any quality from 0 to 11, decompress .br data, and compare the result against gzip — all locally in your browser.
  • Website Compression Test — Enter a URL to see which compression your server sends for each Accept-Encoding, how many bytes it saves, whether its CSS and JavaScript are compressed, and what Brotli could save.

Preguntas frecuentes

How do I unzip a file without WinZip or WinRAR?
Drop the ZIP file on this page. The contents are listed immediately and you can download any file with one click.
Is the ZIP file uploaded?
No. The archive is read in your browser and never sent to a server.
Can I open password-protected ZIP files?
No. Encrypted archives need a desktop tool such as 7-Zip, WinRAR or macOS Archive Utility.
Can I open RAR or 7z files?
No — only ZIP-based formats are supported. RAR and 7z use different compression formats.
Does it work on a phone or Chromebook?
Yes. It runs in any modern browser, including Chrome on Android and ChromeOS and Safari on iPhone.
¿Puedo instalar Unzip Files Online como aplicación web y utilizarla sin conexión?
Sí. Unzip Files Online es una aplicación web instalable (PWA): se instala desde el navegador, no se descarga desde una tienda de aplicaciones. Haz clic en «Instalar aplicación» en la parte superior de esta página en Chrome o Edge (Windows, macOS, Linux, ChromeOS) o, en Android, utiliza «Compartir» → «Añadir a la pantalla de inicio» en iPhone y iPad, o «Archivo» → «Añadir al Dock» en Safari 17+ en un Mac. A continuación, se abrirá en su propia ventana con su propio icono y, como se ejecuta íntegramente en tu navegador, seguirá funcionando sin conexión. Firefox en el ordenador de sobremesa no permite instalar aplicaciones web. Cómo funciona la instalación.
