How to use
- Drop your files into the box above — or click it to browse. Each drop becomes one archive.
- Conversion starts immediately — no settings needed.
- Click Download on each finished file. Nothing was uploaded at any point.
When you need a ZIP (and don't have a right-click handy)
Every desktop OS can zip files, but plenty of situations aren't your desktop: a locked-down work machine or school Chromebook, a tablet, a friend's computer, or a browser-only kiosk. And upload forms that accept exactly one attachment — job applications, submission portals, ticket systems — are the classic reason a folder of files suddenly needs to become one archive.
Every drop becomes one archive: select all the files at once (or drag a selection in), and download a single archive.zip. Need several archives? Drop several batches — each gets its own row and its own ZIP.

What kind of ZIP comes out
A standard ZIP any extractor understands — Windows Explorer, macOS Archive Utility, 7-Zip, unzip. Compressible files (text, CSV, documents, code) are DEFLATE-compressed using the compression engine built into your browser; files that are already compressed (JPG, PNG, MP4, existing archives) are stored without recompression, which keeps them byte-identical and avoids the size increase naive zippers cause. Duplicate filenames are renamed the way file managers do — report.pdf, report (1).pdf — instead of silently overwriting.
When NOT to use ZIP
- For extra compression of media — JPG/MP4 are already compressed; zipping them saves ~0%. Zip media for bundling, not shrinking.
- Password protection — legacy ZIP encryption is weak and this tool deliberately doesn't offer it; use an encrypted 7z/age archive from a desktop tool when secrecy matters.
- Multi-gigabyte backups — browser memory holds the whole archive; the 1 GB per-batch cap here exists for a reason. Use desktop tools for backups.
