Zip it up.
Or open it up.
Bundle files into a .zip, or open an archive and pull out what's inside — entirely in your browser. No upload, no size cap, no account.
How do I unzip (or make) a ZIP online? Drop the archive into Extract to see every file inside and save them; switch to Create to bundle files into a new .zip. Nothing is uploaded — archives with private documents are exactly what this is for.
Zip tool
Standard ZIP and ZIP64 archives work; password-protected ZIPs, RAR, and 7z aren't supported (no password guessing here). For photos and videos, ZIP barely shrinks anything — they're already compressed; it's for bundling, not shrinking. Making a batch of images smaller? That's the bulk image resizer.
How to unzip a file in the browser
- Drop the .zip — it's read locally; nothing is sent anywhere.
- Look inside — every file appears with its size.
- Save what you need — individually, or "Save all" for the lot.
Why local unzipping matters
Most "unzip online" sites upload your archive to their servers, extract it there, and hand you the pieces back — which means everything inside (bank statements, scans, contracts) briefly exists on someone else's disk. This tool opens the archive with a DEFLATE engine compiled to JavaScript, right in your tab. You can verify with the Network panel: after the page loads, nothing moves.
Creating a ZIP, the desktop way — without the desktop
On Windows and macOS you can right-click → Compress to make a ZIP; on a phone, or on a locked-down computer, that's not always available. The Create tab does the same job: add files, pick a compression level (Balanced is right almost always), and download. It's the standard way to send a folder's worth of documents as one attachment — the Gmail guide explains when zipping helps (documents) and when it doesn't (photos, videos).
Good to know
Files come out with their folder paths intact, so nested archives extract correctly. Multi-hundred-MB archives work; multi-GB ones are better on a desktop-class machine with more memory. And the output of "Save all" is the original files, byte-for-byte — extraction never alters content, so checksums match what the sender zipped.
How do I unzip a file online?
Drop the .zip in, and the archive is opened in your browser — you'll see every file inside with its size, ready to save individually or all at once. Nothing is uploaded to a server, so even private archives are safe to open here.
Is there a file size limit?
No server-imposed limit — the practical ceiling is your browser's memory. Typical document and photo archives (hundreds of MB) work fine; multi-GB archives are better handled on a desktop with more headroom.
Can I create a ZIP too?
Yes — switch to the Create tab, add any files, pick a compression level, and download the .zip. It's the same flow as the right-click → Compress on a desktop, without needing a desktop.
Does this open password-protected ZIPs?
No — encrypted archives aren't supported (and we don't guess passwords). Standard ZIPs and ZIP64 work. RAR and 7z are different formats this tool doesn't handle.
