When to use PNG to WebP
WebP can reduce image size for websites while keeping transparent pixels. This conversion uses lossy encoding, so fine lines and small text may change; keep PNG when exact pixel preservation matters.
Quality and file size
WebP output is not guaranteed to be smaller for every image. The browser is checked for WebP encoding support before file selection is enabled.
Frequently asked questions
Does WebP keep transparency?
Yes. The converter preserves the PNG alpha channel in WebP output.
Will the WebP always be smaller?
No. Result size depends on image content and the browser encoder.
Will fine text remain unchanged?
Lossy WebP can soften small text and edges. Keep PNG for exact pixels.
Are images uploaded?
No. Conversion runs locally in this browser tab.
