01
Is the file healthy?
A file can exist on disk and still be damaged. FileInsight checks whether supported content can actually be decoded instead of assuming everything is fine.
Released September 30, 2026 · Native Mac utility
See what’s really
inside a file.
Files carry more information than their names and icons let on. FileInsight opens that hidden layer and turns it into something useful.
Drop in a photo, image, document, or other supported file and inspect its health, actual type, dimensions, software and creator information, metadata, and more — explained in plain English.
A file is more than a filename
The interesting part is often the part you can’t see.
Finder can tell you a file’s name, size, and a few basics. FileInsight goes deeper. It looks at what the file actually contains, checks whether supported files can be decoded, and surfaces the details that help explain where the file came from and what it really is.
02
Is it really what it says it is?
A filename extension is only a label. Type Verification compares that label with what the file itself indicates.
03
What story is hidden inside?
Dimensions, software, creator information, metadata, and other embedded details can reveal far more about a file than its icon ever will.
Drop. Inspect. Understand.
Useful answers, not a wall of technical data.
FileInsight organizes what it finds into understandable sections so you can get the answer you need quickly — while still having the deeper information available when you want it.

Explanation
Plain-English context for what the findings mean
CLEAR
One utility. A lot of curiosity.
Sometimes you just want to know what you’re looking at.
FileInsight is useful when something about a file makes you curious, uncertain, or simply interested in what is hiding underneath the surface.
Photography
See what came out of the camera.
Drop in photographs from Sony, Canon, Nikon, Apple, or other devices and inspect the file details, dimensions, embedded information, and software history that may be present.
Files from elsewhere
Know more before you trust the label.
When a file arrives by download, email, AirDrop, archive, or another source, Type Verification can help show whether the file’s contents agree with what its name claims.
Creators
Understand what your tools leave behind.
Images and other files can retain software and creator information. FileInsight makes those details easy to see when they are present.
Everyday Mac use
Answer the “what is this?” question.
Old files. Mystery downloads. Images with strange dimensions. Files that will not open. FileInsight gives you a better starting point than guessing from the filename.
Local. Focused. Understandable.
Your file does not need to leave your Mac just to be understood.
Private by design.
FileInsight is designed as a native local Mac utility. There is no account to create, no cloud dashboard to manage, and no need to upload a personal photograph or document to a website simply to inspect it.
