Open archives in your browser

Everything the 7-Zip engine reads: ZIP, 7z, RAR and RAR5, TAR, GZIP, BZIP2, XZ, Zstandard (.zst), LZMA, CAB, ISO, WIM, CPIO, DEB, RPM, plus ZIP-based containers such as JAR, APK and WAR. A compressed tarball (.tar.gz) lists the inner .tar — click Open to browse it in place.

Enter the password when prompted — it is used only by the local WebAssembly engine and never transmitted. AES-256 and legacy ZipCrypto ZIPs, AES-encrypted 7z (including archives with encrypted file lists) and encrypted RAR5 are supported.

Only a SHA-256 hash. The file is extracted and hashed locally, then the VirusTotal report page for that hash opens in a new tab. If the file has ever been scanned by anyone, you see verdicts from 70+ antivirus engines without uploading anything. Unknown hash? The report is empty — uploading the file to VirusTotal is then your explicit choice.

Previews show at most the first 20 lines or 5000 characters. The extractor is stopped as soon as those bytes are produced, so previewing a huge log inside an archive costs almost no memory or time. Use Download to extract the whole file.

The archive itself is read in slices, so multi-gigabyte archives list fine. Extracting a single file (preview, download or scan) is capped at 512 MB per file — the practical ceiling of WebAssembly memory inside a browser tab.

Safer than opening them on your desktop: nothing is executed. Text is rendered as plain text, images and PDFs are shown by the browser's own viewers, and the page's Content-Security-Policy blocks all external requests. For suspicious executables, use Scan to check the hash on VirusTotal before touching the file.
