FileHint

application/zip

The MIME type for ZIP archives — the OS-agnostic default for compressed bundles of files.

Typical extensions

Primary uses

  • Shipping multiple files as a single download
  • Serves as the inner container for Office files (docx/xlsx/pptx) — they have their own MIME but are ZIP under the hood
  • Android APKs and Java JARs

In a browser

Typically downloaded, not opened inline. Some browser extensions and cloud storage UIs offer preview of archive contents.

On a server

When serving large archives, set `Content-Length` correctly and enable `Accept-Ranges: bytes` so clients can resume interrupted downloads.

In email

Corporate mail gateways aggressively scan ZIPs; password-protected archives are commonly quarantined because they cannot be inspected.
