Handy for

Emailing many files

Send one attachment instead of twenty.

Submitting assignments

Upload a whole project folder to a portal that accepts a single ZIP.

Sharing photos

Bundle an album into one download for family or clients.

Archiving

Keep a folder’s exact structure in one file for backup.

Good to know

  • Photos, videos, MP3s and PDFs are already compressed — they barely shrink, so Store saves time.

  • Text, code, CSV and Word/Excel files usually shrink a lot with Best.

  • If two files share a name, the second is renamed (e.g. “report (2).pdf”) so nothing is overwritten.

Questions

Can I add a password?

No. There’s no reliable open-source browser library that writes AES-encrypted ZIPs, and the older ZIP password scheme is easily broken, so it isn’t offered. For PDFs use Add Password.

Will the ZIP open on Windows and Mac?

Yes — it’s a standard ZIP that Windows, macOS, Linux, Android and iOS open with their built-in tools.

Are file dates kept?

Yes, each file’s modified date is stored in the ZIP (dates before 1980, which ZIP can’t store, are set to today).

Are my files uploaded anywhere?

No. The file is opened and processed by your browser on your own device — nothing is sent to a server, logged or stored. You can disconnect from the internet after the page loads and the tool keeps working.
