Graphic Inspector for Mac: A Detailed User Guide

Graphic Inspector is a professional image file metadata and information inspection tool designed specifically for macOS. It goes beyond the capabilities of the system’s native “Preview” app, providing designers, developers, photographers, and content managers with the ability to gain deep insight into the internal details of image files. This guide will walk you through its core interface, complete workflow, and efficient usage tips in detail.

I. Detailed Explanation of the Core Interface and Workspace

After launching Graphic Inspector, you will see a clean and efficient single-window interface, mainly divided into four core areas.

1. Title Bar and Toolbar

The top area of the window. The left side displays the name of the file currently being viewed, and the right side contains a series of function buttons:

• Quick Toggle Button: Switch between “Inspector” and “Compare” modes.
• Action Menu: Contains global actions such as exporting reports and copying information.
• Display Options: Control whether to show hidden files, adjust the interface layout, and more.

2. File Navigation Sidebar

Located on the left side of the window. By default, it displays all image files currently open or added to the workspace in a list or thumbnail format. You can select, sort, or remove files here.

3. Core Information Panel

The main central area of the window, organized in tabbed form, is the core of the software:

• Overview: Displays file thumbnails and basic attributes (dimensions, format, size, creation date).
• Metadata: Lists all embedded metadata in a detailed, expandable tree structure (EXIF, IPTC, XMP, GPS, TIFF, etc.).
• Color: Analyzes the file’s color space, color profile, bit depth, and other information.
• Fonts (for SVG/PDF): Lists all fonts embedded in the file.
• Raw Data: An advanced view that displays the file’s binary content in hexadecimal and text form.

4. Detailed Information and Preview Pane

Usually located on the right side of the window. The upper section shows a real-time preview of the selected file, while the lower section dynamically displays detailed key-value pair information based on the specific item selected in the core information panel.

II. Complete Workflow: From Opening Files to Exporting Reports

Step 1: Open or Add Image Files

Method 1: Drag and Drop
Drag image files directly from Finder into the Graphic Inspector window or onto its Dock icon.

Method 2: Use Menu or Keyboard Shortcut
Click the menu bar File -> Open... or use the shortcut Command (⌘) + O, then select files from the dialog box.

Method 3: From Finder Context Menu
Right-click one or more image files in Finder and select “Open With” -> “Graphic Inspector”.

Step 2: Check and Analyze File Information

1. In the File Navigation Sidebar, click to select the file you want to analyze.
2. In the Core Information Panel, switch between different tabs to view various types of information.
   • In the “Metadata” tab, click the triangle icon to the left of each item to expand and view specific parameters.
   • Click on a specific parameter (such as “Pixel Dimensions”), and its detailed content will be displayed in the detailed information pane at the bottom right.
3. Use Comparison Mode: click the “Compare” button in the toolbar, then select two files in the sidebar to compare their attribute differences side by side.

Step 3: Copy or Export the Information You Need

Copy Specific Information: In the information panel, right-click any item and select “Copy” or use the shortcut Command (⌘) + C to copy the name and value of that information item.

Export a Complete Report:

1. Make sure the target file is selected in the sidebar.
2. Click the menu bar File -> Export Report... or use the shortcut Command (⌘) + Shift + E.
3. In the dialog that appears, select the report format (such as plain text, XML, JSON), which categories of information to include, and specify the save path.
4. Click “Export” to finish.

III. Advanced Tips for Common Features

1. Batch Inspection and Filtering

Drag all the image files in an entire folder into the software sidebar at once to quickly browse the basic properties of all files. Use the search box at the top of the sidebar to quickly filter the file list by file name.

2. Deep Metadata Search

In the “Metadata” tab, you can not only view common shooting parameters, but for PSD files containing layers, you can view detailed information such as the name and blend mode of each layer; for PDF files, you can check their compression method, version, and security settings.

3. Color Space Verification

On the “Color” tab, focus on “Color Space” and “Color Profile.” This is crucial for ensuring accurate colors in print products or using sRGB for web images. If “Untagged” is displayed, it means the file lacks a color profile.

4. Using the “Raw Data” View for Troubleshooting

When encountering corrupted or unrecognizable image files, the “Raw Data” view can help advanced users inspect file header information and determine whether the file format is intact or whether the identifier is correct.

IV. Common Problems and Solutions

Problem 1: The software cannot open or recognize certain image files.

Possible Causes and Solutions:

• The file is corrupted: Try opening it with other professional software to verify.
• The format is too new or unsupported: Graphic Inspector mainly supports mainstream bitmap and vector formats (such as JPEG, PNG, GIF, TIFF, BMP, PSD, PDF, SVG, WebP, etc.). Check the software’s official documentation to confirm the list of supported formats.
• File permission issue: In Finder, check the file’s “Show Introduction” to make sure the current user has read permission.

Problem 2: Metadata is incomplete or empty.

Possible Causes and Solutions:

• The file itself has no embedded metadata: Many images that have been compressed or downloaded from the internet have their metadata stripped to reduce size, and this is normal.
• The wrong tab is being viewed: For example, the EXIF information of a JPEG photo is under the “Metadata” tab, not the “Overview” page.
• Software cache issue: Try restarting Graphic Inspector.

Problem 3: Difference highlighting is not obvious in comparison mode.

Solution: In comparison mode, carefully check the information list. Items with differences are usually indicated by bold text, a different color (such as a light yellow background), or a difference icon next to them. Make sure you are viewing the tab that contains the specific information (such as “Metadata”).
