Pix42

Pix42 is a fast, modern, and versatile media viewer for Windows and macOS, designed for smooth browsing, quick previews, and broad file compatibility. It supports a wide range of image formats, from everyday files such as JPEG, PNG, BMP, GIF, TIFF, and WebP to modern standards like AVIF, HEIC/HEIF, JPEG 2000, and JPEG XL. Pix42 also opens professional and technical formats including RAW camera files, PSD, FITS, and OpenEXR, making it useful for photographers, designers, researchers, and users who regularly work with mixed media collections. Beyond static images, Pix42 can play animated formats, video, and audio files, so you can review many types of media without constantly switching between different apps. Pix42 includes practical tools for everyday browsing and curation: a responsive thumbnail filmstrip, folder navigation, archive-as-folder browsing, metadata viewing and editing, star ratings, pick/reject flags, search with metadata support, compare mode, duplicate scanning, slideshow mode, clipboard preview copy, and non-destructive image adjustments. It also keeps a local SQLite-backed asset catalog, so ratings, flags, thumbnails, adjustments, and related file information can stay associated with your media even when files are renamed or moved. For advanced workflows, Pix42 includes support for color-managed viewing, FITS-specific tools such as histogram and stretch controls, optional GPU acceleration, web image optimization, and resolution analysis tools. Built for speed, compatibility, and practical file management, Pix42 gives you a clean desktop experience for browsing, reviewing, organizing, and consuming media across both Windows and macOS.
