RAR & 7Z Viewer: Free Online Tool & Complete Guide

What is the RAR & 7Z Viewer?

RAR and 7Z are the two most common compressed formats after ZIP — software downloads, game mods, backup bundles and shared project archives arrive packed in them every day. Unlike ZIP, neither is readable by your operating system or browser out of the box, so opening one usually means installing a dedicated program or uploading your archive to a website you do not trust.

This RAR and 7Z viewer opens these archives directly in your browser with WebAssembly — no installation, no upload. It lists every file with its real size, previews text, code and images without extracting anything, downloads single files on demand, and bundles selected files into a fresh ZIP. The same engine also reads TAR, GZ, BZ2, XZ and ISO archives, and a built-in security scan flags malicious paths and oversized archives before anything is opened.

Frequently asked questions about the RAR & 7Z Viewer

Here are the answers to the questions people ask most about the RAR & 7Z Viewer.

• Can my browser really open RAR files? — Yes — this tool runs the libarchive engine as WebAssembly inside your browser, so RAR, 7Z and a dozen other formats open natively without any software to install.
• Is it safe to open a RAR from the internet here? — Files are never uploaded. A built-in security scan checks every entry for malicious paths (path traversal, absolute paths) and oversized archives, and locks flagged files behind an explicit confirmation before they open.
• Can I open password-protected RAR files? — Yes — when an encrypted archive is detected, the tool shows a password field. Enter the password to preview or extract the files. The password is used locally and never transmitted.
• What other formats does the viewer support? — Beyond RAR and 7Z it reads ZIP, TAR, GZ, BZ2, XZ, ISO and CPIO archives — anything the libarchive engine supports, all in the same interface.
