Make a ZIP Without Uploading
Create ZIPs entirely in your browser. Your files never touch a server, never get cached, never get logged.
Why "No Upload" Matters
Most online ZIP makers work like this: you upload your files → the server zips them → you download the result. That means a copy of your files lives, even briefly, on someone else's machine. For most files this is fine. For some it isn't: • Legal documents, contracts, signed agreements • Medical records, insurance forms • Tax returns, bank statements, financial records • Source code under NDA • Personal photos, ID scans, passport copies • Anything covered by GDPR, HIPAA, or similar rules For those, the safest option is a tool that doesn't upload at all.
How a Local ZIP Tool Works
tarpanda runs the ZIP engine entirely inside your browser. The flow: 1. You drop files onto the page — they go into the browser tab's memory 2. The engine compresses them right there in the tab 3. The finished ZIP comes back as a download from your own browser At no point does the file get sent over the network. You can verify this in your browser's DevTools → Network tab — you'll see the page load, but no upload requests when you create a ZIP.
How to Tell If a Tool Actually Uploads
Quick checks before trusting any "online" ZIP maker: • Open DevTools (F12) → Network tab → try a small file → look for POST requests with file content • Try it offline — if it works without internet after the page loads, it's local-only • Read the privacy policy carefully — "deleted after X hours" still means it was on their server • Look for words like "in-browser" or "client-side" in the marketing • Check the response time — if a 1 GB ZIP appears in 2 seconds, it can't have been uploaded

Open your browser's DevTools (F12), go to the Network tab, then create a ZIP. You'll see no upload requests — only the initial page load. You can also use tarpanda after disconnecting from the internet; it still works.
Usually faster, because there's no upload/download round-trip. The compression itself runs at near-native speed. For typical files you won't notice a delay at all.
Browser tabs have access to multiple GB of RAM on a typical computer. Files up to a few GB work fine. For very large archives (10 GB+) a desktop tool may still be more comfortable.
