Bundle documents, images and any files into one compressed ZIP — built entirely in your browser, so private files stay private.
Most "zip online" services upload your files to their servers, archive them there, and send the result back. That's a strange trade for a task your own computer handles in seconds — especially with contracts, IDs, or financial documents. This tool runs the entire process locally using your browser's built-in compression engine: pick files, click Create ZIP, done.
ZIP's deflate algorithm hunts for repetition. Text-heavy files — documents, spreadsheets, CSVs, code, logs — are full of it and routinely shrink 50–80%. Media files like JPG photos and MP4 videos are already compressed, so zipping them mainly bundles rather than shrinks; this tool detects when compression wouldn't help and stores those files as-is, so your archive is never larger than the originals.
Email a folder's worth of files as one attachment; bundle a project for a client; group scans and receipts for records; get multiple files under an upload limit that only accepts one. Because everything is standard ZIP, recipients just double-click to open — no special software on either end.
No. The ZIP is assembled entirely in your browser's memory using the CompressionStream API — your files never leave your device, which matters when zipping private documents.
It depends on content. Text, documents, spreadsheets and code often shrink 50–80%. Already-compressed files (JPG, MP4, existing ZIPs) barely shrink — the tool detects this and stores them as-is so the archive never grows.
Up to 50 files and 500 MB total per archive — a browser-memory guard. For bigger jobs, split into multiple ZIPs.
Yes — the output is a standard ZIP readable by Windows Explorer, macOS Finder, and every archive tool.
