WebP Viewer — Open .webp Files with XnView

WebP is a modern image format developed by Google and published in 2010. It supports both lossy and lossless compression, alpha transparency and animation, typically producing smaller files than JPEG or PNG. XnView MP reads and writes WebP natively on Windows, macOS and Linux. XnConvert performs bulk conversion to and from WebP with optional resize, watermark or metadata steps.

About the WebP format

WebP was announced by Google in September 2010 as a modern image format for the web. It uses VP8 (lossy) or a custom predictor-based algorithm (lossless) for compression. WebP typically produces files 25-35% smaller than equivalent PNG (lossless mode) and 25-30% smaller than equivalent JPEG (lossy mode), while keeping similar visual quality. Animated WebP extends the format with multiple frames, comparable to animated GIF but with full alpha and better compression.
