Create a ZIP Archive Online — Without Uploading Anything

DEFLATE compresses redundancy, and JPEGs, PNGs, MP4s, MP3s and PDFs are already compressed — there is little left to squeeze. Text, CSV, JSON, logs and source code routinely drop by 70–90%. A ZIP of photos is about bundling, not shrinking.

Not here. The original ZipCrypto cipher was broken decades ago and offers no real protection, and AES-encrypted ZIPs have no browser implementation solid enough to stake your data on. A tool that pretended otherwise would be selling false confidence — use 7-Zip or your operating system's own encryption instead.

Yes, when you drop a folder rather than individual files — the browser reports each file's relative path and it is preserved inside the archive. Switch on "flatten" if you would rather everything sat in the root.
