Use the PNG to WebP in three steps
Choose a PNG
Open a transparent or opaque PNG image.
Choose the quality
Balance visible detail against output file size.
Download WebP
Save the converted image with the same dimensions.
Transparency can remain transparent
Unlike JPEG, WebP supports an alpha channel. Transparent parts of the PNG stay transparent when the browser encodes the result.
Choose the format based on the asset
WebP is often efficient for web delivery. PNG can still be preferable for lossless editing, archival masters, or tools that do not accept WebP.
PNG to WebP FAQ
Will transparent PNG areas stay transparent?+
Yes, provided the browser's WebP encoder supports alpha, as current major browsers do.
Does WebP use lossy compression here?+
The quality control asks the browser for a quality-adjusted WebP output.
Why can a simple PNG be smaller than WebP?+
Flat graphics with few colors can compress extremely well as PNG, especially when already optimized.
Are dimensions preserved?+
Yes. Width and height remain the same.
Can I convert a screenshot?+
Yes. Use a higher quality value to keep small text and interface edges clear.
Will metadata be retained?+
No. The result is rebuilt from decoded pixels without the source metadata.
