WebP Converter
Going to WebP cuts file sizes by 25–35% compared to JPG at the same visual quality — ideal for websites and apps. Coming back from WebP to JPG or PNG makes images open in older software that never learned Google's format.
Drop any mix of WebP, JPG, PNG and more, choose the output format, and every file converts at once with the size before and after shown per row. Everything is encoded by your browser on your own device — no uploads, ever.
Frequently asked questions
Why should I use WebP instead of JPG?
WebP compresses 25–35% smaller than JPG at equivalent quality and supports both transparency and animation. Every current browser renders it, so it is the standard choice for web images. Only pick JPG if you must support very old software.
Will a WebP file open in any app?
All modern browsers and recent versions of Windows, macOS, Android and iOS handle WebP. Some older photo editors and some web forms still reject it — that is exactly when you convert it back to JPG or PNG here.
Is converting to WebP lossless?
You choose: WebP supports both lossless and lossy encoding. At the default quality 90 the result is visually indistinguishable but much smaller; lower the slider for maximum savings, or pick PNG output for strict losslessness.
