Extract Archive

Drop a ZIP, 7z, TAR, or TAR.GZ archive to see its contents, then download one file or extract everything at once. Password-protected ZIP and 7z archives are supported — just enter the password when prompted. Everything happens locally in your browser — nothing is ever uploaded.

Files never leave your device

What This Tool Does

This tool opens ZIP, 7z, TAR, and TAR.GZ archives right in your browser. Drop a file to see a table of every entry — name, size, compressed size, and whether it's a folder — then download a single entry or extract everything in one pass. Password-protected ZIP (AES or ZipCrypto) and 7z (AES-256) archives are supported: enter the password when prompted, and a wrong one is reported immediately instead of producing a broken file.

Supported Formats

FormatPassword supportNotes
ZIPAES-256 and legacy ZipCryptoUnencrypted zips list instantly with no password needed
7zAES-256Only entries that are actually encrypted require a password
TARNot applicablePlain tar has no built-in encryption format
TAR.GZNot applicableDetected automatically; the gzip layer is removed before listing
Tip: RAR archives aren't supported. If a file fails to open with an unsupported-archive message, check that it's really a ZIP, 7z, TAR, or TAR.GZ underneath — some tools rename .rar files with other extensions.

Password-Protected Archives

If an archive (or any entry inside it) is encrypted, listing it prompts for a password before showing the file table. Enter the password used to protect the archive and it unlocks; entering the wrong one shows a clear error instead of silently failing or producing garbage bytes. Once unlocked, that same password is reused automatically for every subsequent download or "Extract all" from that file, so you only type it once per archive.

Nested Folders

Archives keep their original folder structure, so an entry saved inside a subfolder is listed with its full path — for example invoices/2025/march.pdf rather than just march.pdf. This makes it easy to tell apart identically-named files that lived in different folders. When you download an individual entry, only its filename (not the folder path) is used for the saved file, so nothing from inside the archive is written to a matching folder structure on your disk.

Extracting Files

Download entries one at a time from the table, or use Extract all to download every file in the archive in a single pass. Folder entries have no download button since they carry no bytes of their own — only the files inside them do.

Your Files Never Leave Your Device

Every step here — reading the archive, checking passwords, decompressing entries — runs through a small WebAssembly module loaded into your browser tab. Nothing you drop, and no password you type, is ever sent over the network. Closing the tab discards everything; there was never a server involved to leave a copy behind.

If you'd rather build an archive than open one, use Create ZIP or Compress a single file. To confirm a download's integrity before you trust it, see the Hash checker.

Frequently asked questions

Which archive formats can this tool open?
ZIP, 7z, TAR, and TAR.GZ (a gzip-wrapped tar). The tool detects the format from the file's actual contents rather than trusting its extension, so a renamed file still opens correctly as long as its real format is one of these four.
Does it support password-protected archives?
Yes. ZIP archives encrypted with either AES or the older ZipCrypto method, and 7z archives encrypted with AES-256, are both supported. Drop the archive, and if any entry needs a password you'll be prompted for one before you can list or extract it.
Can this tool open RAR files?
No. RAR isn't a supported format — dropping a .rar file returns an unsupported-archive error rather than a file list. Re-export the archive as ZIP or 7z if you control how it was created, or use a dedicated RAR tool for that format specifically.
Is it safe to open an archive here — does it get uploaded anywhere?
Yes, it's safe in that sense: nothing is uploaded. The archive is read and unpacked locally using WebAssembly running inside your browser tab, including decrypting password-protected entries — none of it, including the password you type, ever leaves your device.
Why do some entries show a folder path instead of just a filename?
Archives preserve their original folder structure, so an entry originally saved as photos/2024/trip.jpg is listed exactly that way rather than just trip.jpg. This lets you tell apart same-named files that lived in different folders, and downloading that entry keeps only the filename itself — the path is stripped for the download name, never followed or recreated on your disk.
What happens if I enter the wrong password?
You'll see a clear "Wrong password" message and the file list stays locked — nothing partial or corrupted is produced. Re-enter the password and try again; there's no limit on attempts.
Can this tool create a 7z archive or a password-protected ZIP?
No — this tool only opens and extracts existing archives, it doesn't create new ones. If you want to build a ZIP from your own files, use Create ZIP; note that tool produces a plain, unencrypted ZIP with no password option, and doesn't produce 7z files.
Is there a limit on how large an archive can be?
No limit is imposed by this tool or a server — everything happens in your browser's memory, so the real ceiling is how much RAM your device has available. A heads-up appears for archives above roughly 100 MB, since very large ones take longer to list and extract.
