ZIP File Extractor

Why extract a ZIP in your browser

Most operating systems can open a ZIP file natively, but sometimes you just want to quickly peek inside an archive, on a locked-down computer, a shared machine, or a mobile device, without extracting it to disk or installing anything. This tool reads a ZIP archive entirely in your browser, lists everything inside it, and lets you download individual files or the whole set again, all without ever writing anything to your file system except what you explicitly choose to save.

How the listing and extraction work

Using the JSZip library, the tool loads the archive's central directory to build a complete list of every file inside, including files nested in subfolders. Each entry appears with its own download link, so you can grab just the one file you need rather than extracting the entire archive if that's all you're after.

Downloading everything at once

If you do want the full contents, the Download All button reads every file back out of the archive and repackages them into a fresh ZIP file for you to save in one step, which is useful when you want to keep working with the same bundle of files rather than downloading dozens of them individually.

Where this is useful

This is handy for checking what's actually inside a ZIP someone sent you before committing to a full extraction, for pulling a single file out of a large archive without downloading everything, or for working with ZIP files on devices where installing a dedicated archive manager isn't practical or allowed.

A note on encrypted archives

This tool reads standard, unencrypted ZIP files. Password-protected or encrypted ZIP archives require the correct password to decode the compressed data, and that capability isn't included here; you'll need dedicated archive software that supports ZIP encryption for those files.

Step-by-step walkthrough

Drop your .zip file onto the upload area or click to browse for it. The tool reads the archive's internal listing within moments and displays every file it contains, including anything nested in subfolders, each with its own individual download link. If you'd rather grab everything at once, click Download All to save every file repackaged into a single fresh ZIP, rather than downloading each entry one at a time. This two-step approach, browse first and then choose exactly what to save, is usually faster than extracting everything when you only need one or two files out of a much larger archive.

Privacy and performance

Because the zip file extractor runs as JavaScript inside your own browser tab rather than on a remote server, there's no upload step, no waiting on a network connection, and no copy of your file sitting on someone else's infrastructure afterward. That also means it keeps working exactly the same whether your file is a few bytes or several megabytes, limited only by your own device's memory rather than a server's queue or rate limit. If you ever want to double-check that nothing is being transmitted, your browser's built-in developer tools network tab will show no outgoing request for the file's contents at any point during conversion. This also means the tool keeps working offline once the page has loaded, and closing the tab afterward leaves no copy behind on any server, since one was never made in the first place. That's a meaningful difference from typical online converters, which usually require uploading your file to a remote service before you ever see a result.
