A zip file compresses one or more files into a single, smaller package, making it easier to download, upload, or transfer. In WordPress, you’ll run into zip files most often when installing plugins and themes.
Where Zip Files Come Up in WordPress
- Installing a premium plugin or theme purchased outside the official directory.
- Downloading a full site backup.
- Exporting media or content in bulk.
Installing a Plugin From a Zip File
From your dashboard, go to Plugins → Add New → Upload Plugin, then choose the zip file from your computer. WordPress unpacks and installs it automatically, without you needing to extract anything manually beforehand.
A Quick Note on Safety
Only upload zip files from sources you trust. Since a plugin or theme zip file contains executable code, uploading one from an unfamiliar source could introduce malicious code onto your site.
