Before you extract anything, it helps to know what is actually in the archive. This free zip viewer lists every file inside a ZIP — names, folders, and sizes — without extracting a single file to your device. Everything runs in your browser, so nothing is uploaded and no account is needed.
How to use this zip viewer
Three quick steps — no signup, no cost.
Select the ZIP file you want to inspect.
The full file list appears, with folder paths and sizes, so you can see the archive’s structure.
Note the files you need, then extract them with an extractor — or close the tab, having extracted nothing.
Why peeking with this zip viewer comes before extracting
A look inside first prevents a messy folder later.
Viewing only reads the archive’s listing, so your downloads stay clean until you choose to extract.
A misnamed file, an unexpected folder, or a bloated extra is visible before it lands on your machine.
Folder paths show how files are grouped, which matters when an archive holds hundreds of entries.
The listing is read on your device, so the archive’s contents never leave it.
Viewing a ZIP is not extracting a ZIP
Two jobs that look alike, and why keeping them apart is useful.
Viewing reads the index. A ZIP file carries a central directory — a list of its entries, their paths, and their sizes. A viewer reads that list and shows it to you. Nothing is decompressed onto your device, and nothing appears in your downloads.
Extracting writes files. An extractor decompresses entries and saves real files, which then occupy disk space and need managing. That is the right step once you know which files you want.
Use the viewer first when the archive is unfamiliar. A download from a stranger, a backup you have not opened in years, or an archive with hundreds of entries all deserve a look before extraction — especially if disk space is tight or you only need one file out of many.
ZIP Viewer FAQs
Short, direct answers to the questions readers ask most.
The archive’s file list: every entry’s name, its folder path, and its size. It does not write any extracted file to your device.
No. Viewing lists contents only; to use a file, extract it with a ZIP extractor and open the extracted copy.
No, and the difference matters: viewing reads the archive’s index, while extracting writes real files to disk. This tool only does the first.
Yes. Entries are listed with their full paths, so files inside subfolders appear under those folders.
No. An encrypted archive hides its listing too, so it cannot be viewed here without being decrypted first.
