Create ZIP
Drop files - get a ZIP back.
About this tool
Bundle any files into a single .zip archive directly in your browser. Useful for sending multiple files in one email attachment, sharing a project as a single download, archiving a folder, or shipping deliverables to a client.
Privvert uses standard deflate compression (the same as every other ZIP tool), so the archives open in macOS Finder, Windows Explorer, 7-Zip, WinRAR and every other major tool. Runs entirely in your browser.

Frequently asked questions
Yes, with deflate. Already-compressed inputs (JPG, MP4, MP3, PDF) won't shrink much further because they're already efficiently encoded; text and uncompressed binaries shrink significantly.
Encrypted ZIPs are on the roadmap. For now, ZIP first then encrypt the archive with a desktop tool like 7-Zip if you need a password.
Drag a folder into the drop zone and Privvert preserves its structure inside the archive. Browser folder support varies - Chrome and Firefox handle it; older browsers may flatten.
Practically no - the limit is your browser's memory. Thousands of small files work fine on desktops.
For already-compressed formats (JPG, MP3, MP4) the difference is negligible - those files are already near their entropy limit. For text, source code or uncompressed files, 7-Zip's LZMA usually beats classic ZIP by a noticeable margin, at the cost of slower compression.
Yes. Standard ZIP is supported natively on Windows, macOS, iOS and Android. Password-protected ZIPs may prompt for a tool on iOS but extract fine everywhere else.
