N1 Viewer is a native Windows application built for browsing, culling, inspecting and comparing image collections. It combines preview-first navigation with persistent SSD caching, direct GPU or iGPU selection, high-precision SDR, HDR and wide-gamut output, advanced color management, batch tag and metadata editing, and a choice between Modern and Classic interface layouts. The program handles JPEG, HEIC, AVIF, PNG, WebP, TIFF, PSD, OpenEXR, JPEG XL and many RAW formats from major camera manufacturers. Filmstrip, Gallery and Culling modes provide ratings, Pick or Reject flags, labels and auto-advance for organizing large folders. Comparison views, adjustable thumbnails, filename and folder search, filters and multi-select support detailed review. The color pipeline covers color-managed SDR, Wide Gamut and HDR presentation through Windows Advanced Color, with ICC profiles, 8-bit to 16-bit decode paths and HALF or FLOAT HDR sources.

Preview-first navigation. This function preloads nearby images using an adaptive preview runway and persistent SSD caching, so moving through a folder does not require waiting for each file to decode from storage. The current image loads at full quality while adjacent files are prepared in advance, reducing delays during sequential review and allowing rapid assessment of large image sets without manual preloading.
GPU, iGPU and CPU render path selection. The program permits direct switching between graphics processor, integrated graphics and central processing unit rendering paths. This selection changes the balance between speed, power consumption and hardware compatibility depending on the machine in use. Users can assign the most suitable path for their system without modifying operating system settings or restarting the application.
Color-managed SDR, Wide Gamut and HDR output. The color pipeline supports standard dynamic range, wide gamut and high dynamic range presentation through Windows Advanced Color. Extended ICC processing covers Adobe RGB, Display P3, DCI-P3, ProPhoto RGB, Rec.2020, Rec.2100 PQ and HLG, HDR10 and PQ, linear scRGB and custom embedded ICC profiles. Supported decode paths accept 8-, 10-, 12- and 16-bit sources as well as HALF and FLOAT HDR sources.
Filmstrip, Gallery and Culling workflows. Three viewing modes organize image review. Filmstrip places a horizontal sequence beneath the main preview. Gallery arranges thumbnails in a grid for overview and selection. Culling mode combines ratings, Pick and Reject flags, color labels and auto-advance to move through a set and mark selections. These modes support different stages of sorting and narrowing a collection.
Two-image and four-image comparison. Comparison views place multiple images side by side for direct evaluation. The two-image layout suits before-and-after checks or variant selection. The four-image layout supports broader comparison across a small group. Synchronized navigation and consistent scaling help identify differences in detail, color, exposure and composition without opening separate windows.
Batch tag and metadata editing. This function applies tags, ratings, labels and metadata changes to multiple selected files at once. It operates alongside culling tools and supports large local image sets. Batch operations reduce repetitive manual entry when organizing folders, preparing images for delivery or maintaining consistent descriptive information across a project.
Filename and folder search with filters. Search locates images by filename or folder path. Filters narrow the visible set according to selected criteria. Combined with multi-select and Explorer-order persistence, these tools help isolate specific files within large directories. Results remain within the image workflow, avoiding separate file manager windows or external search utilities.
Duplicate Search for exact and near-duplicate images. The duplicate detection function finds identical files as well as near-duplicates that differ in filename, format, resolution or compression. This capability assists in cleaning archives, removing redundant copies and identifying multiple versions of the same source image. Results can be reviewed and managed directly within the application.
Local AI visual and semantic search. Optional artificial intelligence features provide visual and semantic search, Find Similar and reference-image search. Processing runs locally using GPU, iGPU or CPU acceleration. Auto Tags in Fast and Detailed modes generate descriptive keywords. AI-generated titles and descriptions, metadata suggestions and OCR text search extend organization and retrieval without sending image data to external services.
Touch and pen gestures with multi-monitor support. The application accepts touch and pen input for navigation and selection. Multi-monitor configurations allow the interface and image views to be arranged across several displays. Photoshop and Lightroom handoff passes files to external editors. Modern and Classic interface layouts provide different arrangements of controls and panels for varied working preferences.

N1 Viewer was created by the developer N1 Viewer and has been available since 2023. The program is written in C++ with native Windows APIs and hardware-accelerated rendering components. Development focused on combining fast local file system browsing with advanced color management, broad format support and optional on-device AI processing.
