About

How to Open WebP Files on Windows with VoidImageViewer
Double-click the file
Install VoidImageViewer and choose the file-association option in its setup wizard. From then on, double-clicking a .webp file in File Explorer opens it instantly — including animated WebP.
Use “Open with”
In Windows 10/11 File Explorer, right-click the .webp file and choose Open with → Choose another app → Void Image Viewer. Tick “Always use this app to open .webp files” to make it the default.
Drag it into the viewer
Launch VoidImageViewer and drag one or more .webp files — or an entire folder — from Explorer into the window. Animated WebP plays with pause and frame-step controls.
Preview online without installing
Drop the .webp into the preview tool at the top of this page. It runs entirely in your browser: the image renders locally and is never uploaded to a server.
Why Open .webp Files with VoidImageViewer
VoidImageViewer is free and open source under the MIT license — no ads, no sign-up and no telemetry of any kind. The app is under 5 MB, works fully offline, and every download ships with a SHA256 checksum you can verify before installing. It decodes WebP natively — including animated WebP — alongside dozens of other formats, so there are no codec packs to hunt for.
