How to create a ZIP file online

  1. Add your files. Drag and drop any files into the box above, or click it to browse. You can keep adding more files, and remove any you added by mistake.
  2. Name the archive and pick compression. Type a name for the ZIP and choose a compression level — Normal is a good balance of speed and size for most files.
  3. Create and download. Press Create ZIP, check the resulting size, and download your archive with one click.

About this tool

This free ZIP maker packs any collection of files — documents, photos, spreadsheets, code, audio — into one standard .zip archive that opens on Windows, macOS, Linux, Android and iOS without extra software. It is handy for emailing several attachments as a single file, tidying up downloads, or shrinking text-heavy files before sharing. Files that are already compressed (JPG photos, MP4 videos, other ZIPs) will not shrink much, which is normal for the ZIP format.

Unlike upload-based archive services, everything here runs locally in your browser using JavaScript. Your files never leave your device, there are no size quotas imposed by a server, no sign-up and no watermarks — the tool even works offline once the page is loaded, so it is safe to zip private or confidential documents.

Frequently asked questions

Are my files uploaded to a server?

No. The ZIP archive is built entirely in your browser's memory using the JSZip library. Nothing is transmitted over the network, which makes the tool suitable for sensitive files.

How many files and how much data can I zip?

There is no fixed limit — it depends on your device's memory. Archives of a few hundred megabytes are typically no problem on a modern computer; multi-gigabyte archives may fail on low-memory devices because everything is held in RAM while zipping.

Why is my ZIP barely smaller than the originals?

ZIP compression works best on text-like data (documents, CSV, code, logs). Photos, videos and music are already compressed, so re-compressing them saves little. Choose Store only for such files to speed things up.

Can I add two files with the same name?

Yes. A ZIP archive cannot contain two identical file names, so the tool automatically renames duplicates, e.g. report.pdf and report (1).pdf.
