What this tool does
PNG to WebP draws the decoded PNG onto a transparent canvas path (no white fill) and encodes WebP. Alpha survives when the browser encoder supports it.
What this tool does not claim
It does not claim lossless or pixel-perfect output. Quality settings still apply lossy compression to color data.
When to keep PNG
Keep PNG if a destination requires it or if you need a guaranteed lossless still without WebP encoder variance.
