Adaptive preview runway
Preview-first navigation dynamically preloads nearby images, backed by persistent SSD caching, then automatically loads full quality for the current image.
Fast and fluid Windows image viewer with a high-precision SDR, HDR, and wide-gamut color pipeline.
N1 Viewer
Fast image browsing — with more control.
N1 Viewer is a fast native Windows image viewer built for anyone who wants more control than a typical viewer offers. It combines ultra-fast browsing, true Windows Explorer order, direct GPU / iGPU / CPU selection, high-precision HDR and wide-gamut output, advanced color management, batch tag and metadata editing, and a customizable Modern or Classic interface — all in a local-first workflow designed for serious image browsing, culling, inspection, and comparison.

Built around the image
Fast where it matters.
N1 keeps browsing close to the Windows file system while preloading what you are most likely to view next.
Explorer-native workflow
True Windows Explorer order, filename and folder search, filters, multi-select, copy and undoable delete without leaving the image workflow.
Choose the render path
Switch directly between GPU, iGPU and CPU paths to prioritize performance, efficiency or compatibility on the machine in front of you.
Inspect without friction
Fullscreen, Clean View, adaptive fit-to-window behavior and fast 100% inspection keep detail checking immediate.
Metadata & tags
Batch tag and metadata editing sits alongside ratings, labels and culling tools for large local image sets.
Flexible interface
Modern or Classic UI, touch and pen gestures, multi-monitor workflows, plus Photoshop and Lightroom handoff.
02
Filmstrip · Gallery · Culling · Compare
Move from browsing to decisions.
Quick 2-image comparison is available directly in the main viewer, while Gallery supports 2- and 4-image comparison. Browse folders and nested subfolders directly from Gallery, then rate, label, Pick / Reject and auto-advance through a set.

Color Management & HDR Pipeline
SDR, Wide Gamut and HDR — one native pipeline.
Use the fast Standard path for common color-managed viewing, or the extended Advanced path for wider-gamut and precision-sensitive HDR workflows.
Fast color-managed viewing
Color-managed SDR / HDR viewing with sRGB and common ICC-managed color profiles.
Extended Wide Gamut / HDR
Adobe RGB, Display P3 / DCI-P3, ProPhoto RGB, Rec.2020, Rec.2100 PQ / HLG, HDR10 / PQ, linear scRGB and custom embedded ICC profiles.
