How ZipTool keeps your files private
ZipTool runs entirely in your browser. When you open an archive, it is parsed locally — ZIP-based formats with zip.js, RAR with a WebAssembly unrar — so there is no upload step, because there is no server that ever receives your file contents.
That is a claim you can check, not one you have to take on trust. Open an archive, then turn off your computer’s internet connection. Browsing the file tree, searching by name, and previewing every file inside the zip keep working exactly as before. A tool that goes silent the moment you disconnect was uploading your data in the background. ZipTool does not.
Keeping processing on your device is a real privacy improvement — but it is not a security guarantee. A malicious archive is still malicious, so only open zips from sources you trust.

Add your archive
Drag a zip, rar, tar.gz, apk, epub, or jar onto the page, paste a direct URL, or pick a file from your device.
Browse and search
The file tree opens on the left. Use search to jump straight to any file by name, even in a large archive.
Click to preview
Code opens with syntax highlighting; images, audio, video, and PDFs render inline; a zip inside another zip opens as its own archive.
Nothing is uploaded
The archive is read locally in your browser and discarded when you leave the page — your files never touch a server.

Frequently asked questions
Is my zip actually uploaded anywhere?
No. ZipTool parses the archive entirely in your browser using zip.js, and your file contents are never transmitted to any server. You can confirm it by opening a zip and then disconnecting from the internet — browsing, searching, and previewing keep working, because nothing depends on a network request.
What can I preview inside an archive?
Source code and config files — JavaScript, TypeScript, JSON, Python, Markdown, HTML, CSS, and many more — open in a syntax-highlighting editor. Images, audio, video, and PDFs render inline. An archive stored inside another archive (a zip or rar nested inside) can be opened as its own archive without leaving the page, and files ZipTool cannot render are still listed by name and size.
Which archive formats can I open?
ZipTool opens .zip, .7z, .rar, .tar, .tar.gz, and .gz, plus ZIP-based containers such as .apk, .epub, .jar, .whl, .xpi, .war, and Office OOXML files like .docx and .xlsx. Encrypted RAR entries and split (multi-volume) RARs are not supported in the browser; everything else previews the same way.
Do I need to install anything or create an account?
Neither. ZipTool is a web page — open it in a modern browser and start using it. There is nothing to download, no sign-up, and no account required.
Can I open a zip from a URL?
Yes. Paste a direct link to an online archive and ZipTool fetches it once into your browser, then parses it locally from there. It is handy for inspecting a download before you commit to it. You can also deep-link with a zip and file parameter to land directly on a specific entry.
Does it work on a phone?
Yes — ZipTool runs in any modern mobile browser. Drag-and-drop depends on your device, but you can use the file picker or paste a URL just as you would on a desktop.
Is ZipTool free?
Yes. Viewing and previewing archives is completely free, and core zip viewing always will be.
