Are my files uploaded to extract or zip them?

No. The ZIP is read and written entirely in your browser. Nothing is uploaded — which is also why there's no file size limit beyond your device's memory.

Can it open password-protected ZIPs?

Encrypted ZIPs aren't supported — browser ZIP libraries can't decrypt them. Use a desktop tool like 7-Zip for password-protected archives.

What's the largest ZIP I can open?

There's no fixed cap, but everything is held in memory, so very large archives (multiple GB) may be limited by your device. Extracting individual files keeps memory use low.

ZIP files, the private way

📥

Grab one file from a ZIP

Bundle files to send

Combine documents or images into a single ZIP for email or upload, without installing anything.

🔒

Sensitive contents

Tax docs, contracts, photos — opened and zipped locally, so confidential files never touch a server.

ZIP tool FAQ

Does it keep folder structure?

When opening, the full path of each entry is shown so you know where files sit. When creating, files are added at the top level (folder upload support is on the list).

Why can't it open my .rar or .7z?

This tool handles ZIP only. RAR and 7z use different formats that browsers can't read natively — a desktop app like 7-Zip handles those.

Is there really no size limit?

No imposed limit — the only constraint is your device's available memory, since processing is local. For huge archives, extract individual files rather than all at once.
