How to Open PNG Files on Windows with VoidImageViewer
Double-click the file
PNG opens out of the box: double-clicking a .png file in Windows 10/11 File Explorer launches the Photos app. For most screenshots and images this is all you need.
Open with a faster viewer
Right-click the .png file → Open with → Void Image Viewer for instant loading, keyboard zoom and folder browsing with the arrow keys. Tick “Always use this app” to make it your default PNG viewer.
Drag files in
With VoidImageViewer running, drag a .png — or a whole folder of them — into the window. Transparent areas render against the viewer background, which makes it easy to check alpha edges.
Or preview in the browser
Drag the .png into the preview tool on this page. It renders locally in your browser — no upload, no install.
