application/zip

File extensions: .zip

The universal compressed archive format.

What is application/zip?

application/zip is the media type for ZIP-compressed archives — the most widely supported archive format on any operating system. It bundles multiple files and directories with optional compression per entry.

Typical usage

Bulk downloads, mail attachments, plugin/theme distributions, backup exports. Modern formats like DOCX, XLSX, EPUB, and JAR are ZIP under the hood.

Common gotchas

Files ending in .docx / .xlsx / .apk are ZIPs internally. Serving them as application/zip triggers a raw download instead of the correct app handler — always send the format-specific MIME type.

HTTP header example

Response header
