File Peek
File Peek is a macOS utility for inspecting files with a hex editor, viewing hashes and metadata, and copying Base64 data.
What is File Peek?
File Peek is a native macOS utility from Tunabelly Software for examining and editing file contents. It helps users inspect binary data in a built-in hex editor, search within files, replace values, and export contents as text or hex when they need a closer look at a file. The app also shows common file hashes including MD5, SHA1, and SHA256, making it useful for integrity checks and comparison workflows. In addition, File Peek can copy Base64-encoded file data and lets users adjust created and modified dates for files. It is aimed at Mac users who need a focused file-inspection tool without the complexity of a larger developer suite.

Safety overview
Status: Safe
File Peek is a legitimate file utility for macOS. Access to files you open is normal for its purpose, and editing file contents or changing file dates can permanently alter those files, so it is best used on copies when you are working with important data. Hash viewing and Base64 copy features are low risk, but any save operation in the hex editor should be done carefully.
Recommendation: Keep File Peek if you use it to inspect, compare, or edit files at a low level. If you no longer need its hex editor and file analysis tools, you can remove it without affecting macOS beyond losing access to those features.
