Archive Viewer

Look inside ZIP, 7Z, RAR and TAR archives in your browser — every file with its size and date — and save any of them.

Before you extract an archive, it often helps to know what is in it: is the file you need there, how big is everything, does the folder structure make sense, and is there anything that shouldn't be there? The Archive Viewer opens ZIP, 7Z, RAR and TAR archives — including .tar.gz, .tgz, .tar.bz2 and .tar.xz — and shows every file and folder with its size and date.

Filter the list to find a file by name, check the total size before unpacking, and save just the files you need, or everything as a ZIP. Password-protected archives ask for the password. It also opens ZIP-based formats such as .jar, .apk, .epub and comic book .cbz files, so you can see what they contain. Archives are checked by their content and opened in your browser — nothing is uploaded.

How to use Archive Viewer

  1. Choose or drop an archive.
  2. Browse or filter the list of files and folders.
  3. Enter the password if the archive is protected.
  4. Save single files, or everything as a ZIP.

Features

  • ZIP, 7Z, RAR (4 and 5) and TAR.
  • Compressed TAR: .tar.gz / .tgz, .tar.bz2, .tar.xz.
  • ZIP-based formats: .jar, .apk, .epub, .cbz.
  • Names, folders, sizes and dates.
  • Filter by name; total size shown.
  • Password-protected archives.
  • Runs in your browser; nothing is uploaded.

Common uses

Check a downloaded file before trusting it, find one invoice in a ZIP of a year's documents, see whether an email attachment really contains only photos, look at what an Android .apk or a Java .jar includes, peek into an .epub e-book, confirm a backup has the latest version of a file by its date, or measure how much space an archive will need once unpacked. Because nothing is extracted until you choose, viewing is quick even for large archives with thousands of files.

Why look before extracting

Viewing first saves time and avoids surprises. You can check that a download contains what it promised before opening anything, find one document in a large backup without unpacking all of it, see whether files are inside a top-level folder, and spot suspicious content, such as program files in an archive that should only contain photos.

Formats

Archives are recognised by their content, not their extension, so a renamed file is still opened correctly, and a file that isn't an archive gets a clear message. Many formats are ZIP files under another name: Java .jar files, Android .apk packages, .epub e-books, comic book .cbz files and Office documents. Those can be opened to see their structure, too. Multi-part archives (.part1.rar, .z01) are not supported; join them first with the program that made them.

Safety

File names are cleaned before they are shown or saved: paths that try to reach outside a folder, absolute paths and characters Windows can't use are removed. Archives that would unpack to a dangerous size are refused. Files are only extracted when you save them, and nothing in the archive is ever run. Archives up to 1 GB can be opened.

Private

The archive is read by libarchive and JSZip, open-source libraries running in your browser, so private backups and documents never leave your device. To create archives, use the ZIP Creator or TAR Creator; for single-format tools, use the ZIP, 7Z, RAR or TAR Extractor.

Frequently asked questions

Which formats can it open?

ZIP, 7Z, RAR, TAR and compressed TAR, plus ZIP-based files like .jar, .apk and .epub.

Yes. Each file has its own download button.
