Unzip One

What is Unzip One?

Unzip One is a macOS utility for working with compressed archives. It helps users open, browse, extract, and create archive files in common formats such as ZIP, RAR, 7z, gzip, and bzip2. The app is aimed at everyday Mac users who download packaged files, receive compressed attachments, or need to bundle files to save space or share them more easily. It also lets you preview the contents of an archive before extracting it, which is useful when you only need a few files from a larger package. For people moving files between Windows and Mac, its wider format support can be helpful compared with basic built-in extraction tools. Trend Micro publishes Unzip One as a focused desktop helper rather than a full file manager or security suite.

• Browse the contents of an archive before extracting files.
• Extract files to a folder you choose.
• Create compressed archives to save space or share files.

• Set it as a default app for supported archive files.

Safety overview

Status: Mostly safe

Unzip One is a legitimate archive utility for macOS. Access to files you choose to open or extract is normal for this type of app, and archive tools may read many files inside compressed packages while they work. As with any unarchiver, use extra care with archives from unknown senders, because compressed files can contain unwanted or deceptive content even when the extraction app itself is legitimate.

Recommendation: Keep Unzip One if you regularly open RAR, 7z, or other archive formats that macOS does not handle as conveniently on its own. If you do not use it, removing it is usually low impact and mainly means those archive files will open with another tool instead.
