How the conversion stays private
This page uses createImageBitmap and canvas.toBlob. After the page has loaded, it even works offline. Animated WebP: only the first frame is exported in this version.
FAQ
Why did my screenshot save as .webp?
Chrome often saves images from the web as WebP. It is efficient, but older Photoshop, some printers, and many upload forms only accept JPG or PNG.
Is the WebP file sent to a server?
No. The browser’s built-in decoder and canvas do the work. There is no WASM download for this tool.
Does transparency survive in JPG?
No. JPG has no alpha channel. Transparent pixels become a white background. Use WebP to PNG if you need the hole.
