qlImageSize
qlImageSize is a QuickLook generator plugin for macOS that extends the system's built-in QuickLook preview functionality to display detailed image metadata inline in Finder previews. When you select an image file and press spacebar in Finder, qlImageSize overlays key information including file size, on-disk footprint, pixel dimensions (width and height), image format, and basic metadata. It supports RAW camera files, HEIC, JPEG, PNG, TIFF and other common image formats. The tool is designed for photographers, designers, and anyone who regularly inspects images without needing to open them in a full editor, helping to quickly assess file properties and speed up image-heavy workflows.
AI Recommendation
1 suggestionqlImageSize is a QuickLook generator plugin that extends macOS's preview system — it is not a standalone application and cannot be updated separately through the App Store or a vendor download page. To ensure you have a native Apple Silicon compatible version, you must reinstall the plugin itself. Visit the Whine website or the SourceForge download page listed in your search results, download the latest version of qlImageSize, and run the installer to update the QuickLook generator on your Mac. Once installed, the plugin integrates into macOS's QuickLook system automatically and will work natively on Apple Silicon Macs. If you are currently running an Intel-only version under Rosetta 2, reinstalling from the latest download will replace it with a native build if one is available from the vendor. Be aware that Apple is removing Rosetta 2 support in macOS 28 (September 2028), so updating to a native build now will ensure the plugin continues to work beyond that date.
