Open any ZIP file right in your browser - see what is inside without unzipping, preview files, unlock password-protected ZIPs and extract only what you need. Got a RAR or 7Z instead? Try the Archive Viewer, or build your own ZIP with the Archive Creator. Unzipping a whole batch? The Archive Extractor handles many archives at once, and ZIP Repair rescues damaged ones.

Old Windows ZIPs store names in a local code page, not Unicode. Names like ÄÔÜ or Ð¿Ñ mean the wrong one - pick another and the list updates instantly.
Test archive integrityUnpacks every file in memory and checks it against its checksum - nothing is saved.
Open your ZIP. Drop a .zip file anywhere on the page, browse for it, or try a sample. Split ZIPs open when you select all the parts (.z01, .z02 ... and the .zip) at once.
Browse and search. Walk through the folder tree, sort by name, size or date, and search names with wildcards such as *.pdf.
Preview files. Click any file to see it - images, text and code, PDFs, audio, video and fonts. Locked files ask for the password first.
Extract what you need. Download one file, tick a few and extract them as a new ZIP, or extract everything. Run Test integrity to check every file before you rely on the archive.

ZIP viewer features
Huge ZIPs, no waiting
Only the ZIP's table of contents is read, so 100,000 files or a 5 GB ZIP64 archive list in about a second.
Password ZIPs
AES-256, AES-128 and classic ZipCrypto. Your password stays in this tab and is never sent anywhere.
Preview without unzipping
Images, text and code, JSON, CSV, PDF, audio, video and fonts open in a click. A ZIP inside a ZIP opens too.
Integrity test
Unpacks every file in memory and compares it with its CRC-32 checksum - the quick way to catch a corrupted download.
Safety report
Flags zip slip paths, invoice.pdf.exe style names, hidden right-to-left tricks and zip bombs.
Readable file names
Old Windows ZIPs store names in DOS code pages. Cyrillic, Japanese, Chinese and Western names are detected and fixed.
Extract your way
One file, a selection or everything - as a fresh ZIP with folders kept, or written straight into a folder on your disk.
100% private
The ZIP is read by your own browser. Nothing is uploaded, and closing the tab clears it from memory.
Password-protected ZIP files
A ZIP can lock its files with a password while the file names stay readable.
There are two kinds of ZIP encryption, and this viewer opens both.
Encryption
Made by
How strong
AES-256 (also 128, 192)
7-Zip, WinZip, WinRAR, Keka, PeaZip
Strong - safe for private files with a good password.
ZipCrypto
Windows Explorer add-ons, old WinZip, zip -e on Linux and Mac
Weak - fine against curious eyes, not against attackers.
Forgot the password? Nobody can read AES files without it - not us, not WinZip. If you made the ZIP yourself, check your password manager first.
Want to send files with a password? Pack them with the Archive Creator or 7-Zip and choose AES-256.
Garbled file names in old Windows ZIPs
ZIP files from older Windows PCs store names in the PC's DOS code page, not in Unicode.
Open them with the wrong code page and you get mojibake like the examples below.

The viewer scores every common code page against the names and picks the one that reads like real words. It gets Cyrillic, Japanese, Chinese, Korean, Greek and Western names right on its own.
Still wrong? Open File name encoding under the file list and pick another one - the list updates instantly, and extracted files keep the fixed names.
Is this ZIP safe to open?
ZIP files are a favourite way to deliver malware by email and chat.
That is why every ZIP opened here gets a safety report in the Archive info tab.
Zip slip - names like ../../startup/evil.bat try to write outside the folder you extract into.
Disguised programs - invoice.pdf.exe, or names with an invisible right-to-left character that make exe look like pdf.
Zip bombs - a few kilobytes that unpack to gigabytes and freeze your PC.
Duplicates and absolute paths - entries that would overwrite each other or land in system folders.
Extracting here is safe by design: paths are cleaned, nothing runs, and duplicate names get a number. The report checks names and structure - for viruses, scan downloaded programs with your antivirus before you run them.
About ZIP files
ZIP is the most widely used archive format in the world.
Phil Katz created it in 1989, and every Windows, Mac and Linux computer can open it today.
A ZIP compresses each file on its own and keeps a table of contents at the end. That is why this viewer can list a huge ZIP instantly and pull out a single file without unpacking the rest.
Most ZIPs use Deflate. Windows Explorer switches to Deflate64 for big files, and 7-Zip and WinZip can use BZip2, LZMA, PPMd or Zstandard - this viewer unpacks all of them, so a ZIP that says "unsupported method" elsewhere opens here.
ZIP vs RAR, 7Z and TAR
RAR and 7Z usually compress smaller but need extra software - open them with the RAR File Viewer or the 7Z File Viewer.
TAR.GZ is the Linux and macOS favourite for backups and source code - the TAR File Viewer shows permissions and links too.
Office files such as DOCX, XLSX and PPTX are ZIPs inside - read them properly in the DOCX Viewer or Excel Viewer.
Drop the ZIP onto this page. The file list appears in a second, and you can open folders, preview files and download only the ones you need - nothing is unpacked to your disk until you choose to.
It works on Windows, Mac, Linux, Chromebooks, iPhone and Android.
Yes. Both modern AES encryption (AES-128, AES-192 and AES-256, as made by 7-Zip and WinZip) and classic ZipCrypto are supported.
File names are usually visible right away, and you are asked for the password when you open or extract a locked file. The password never leaves your browser.
Your ZIP is never uploaded - it is read by your own browser, so private files stay private.
Every ZIP also gets a safety report that flags paths trying to escape the folder (zip slip), programs disguised as documents and zip bombs. The report checks names and paths, it is not a virus scan.
Very big. Only the table of contents is read to list the files, so multi-gigabyte ZIP64 archives and ZIPs with 100,000+ files open in about a second.
Single files of several gigabytes can be saved straight to disk in Chrome and Edge. Building one new ZIP from many gigabytes of files is limited by your device memory.
The ZIP was made on an older Windows PC that saved names in a DOS code page instead of Unicode.
The viewer detects the code page automatically - CP437, CP866 Cyrillic, Shift_JIS, GBK, Big5 and more - and you can pick another one under File name encoding if names still look wrong.
Open the ZIP and press Test integrity. Every file is unpacked in memory and compared with the CRC-32 checksum stored in the ZIP, and damaged files are listed by name.
If the end of the ZIP is missing, for example after a broken download, the viewer still lists the files it can find.
Yes. Click the download icon next to a file, or open it and press Download.
Tick several files or folders to get them as one new ZIP, or use Extract to folder in Chrome and Edge to write them straight to your disk with their folders.
