What this tool is for
WebP keeps the alpha channel, so transparency survives, and it beats PNG on size in both its lossless and lossy modes. Screenshots and flat graphics often drop by half. Your images are processed by your own browser through the Canvas API. They are never uploaded, which means no queue, no size limit imposed by a server, and no copy of your photo sitting in someone else storage.
How to use it
- Drop in your PNG files.
- Choose lossless to preserve every pixel, or lossy for the smallest result.
- Download the WebP output.
