Result

This page opens the ZIP creator ready to zip files online: add any files by drag & drop or the file picker, press the button and download them as a single .zip archive.

The archive is assembled by your own browser, so private documents, photos and project files never leave your device — there is no upload step at all. Add files in several rounds, remove any from the list, and pick how hard to compress them.

Need to look inside an archive instead? Our ZIP Extractor is the companion tool: it opens any .zip in the browser and lets you download the files one by one.

🛡️
Executed in Browser

Your files and inputs never leave this device. Processing runs completely offline. 100% Secure.

Accepted Formats & Rules

  • Multi-file upload with drag & drop, folder structure preserved via relative names.
  • Compression level select: 0 (store), 6 (default), 9 (maximum).
  • Shows the compression ratio achieved after the archive is created.

Key Benefits

✓ Complete privacy: files are compressed locally in your browser and never uploaded to any server.
✓ Real compression control: store only, balanced or maximum level — with the actual size saving shown after creation.
✓ Add files in several rounds and remove any of them from the list before the archive is built.

Use Cases

  • • Need to email a folder of documents as a single attachment instead of a dozen files?
  • • Want to shrink logs, CSV exports or source code before uploading them somewhere with a size limit?
  • • Handing over a project and want one tidy archive with the folder structure preserved?
