How this tool works
PNG pixels are converted to WebP locally in your browser while preserving transparency.
- Choose one or more PNG images.
- Set WebP quality.
- Process and download the results.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.
