How to use this tool
- Select a PNG image and choose the WebP quality.
- Convert and inspect fine edges, small text, and transparent areas.
- Compare the output size with the PNG before downloading.
Formula & method
PNG pixels are decoded and encoded as WebP at the selected quality. Transparency is retained by compatible browser encoders. Compare the original and resulting file sizes, since savings depend on the source image.
A practical example
A PNG logo can be exported as WebP for a smaller web asset while preserving its transparent background.
When this tool is useful
Prepare PNG artwork for a web page when a WebP export offers a useful size reduction. Logos and screenshots deserve a careful visual check because lossy encoding can affect sharp edges or small text.
Common mistakes and limitations
- WebP output is not guaranteed to be smaller than every PNG.
- Check whether the receiving application accepts WebP before replacing a file that needs PNG compatibility.
Frequently asked questions
Can WebP keep a transparent background?
Yes, compatible browser encoders preserve alpha transparency when exporting WebP. Review the output against the background where it will be used.
Is converting back to PNG a way to undo quality loss?
No. A PNG made from a lossy WebP stores the already decoded pixels. Keep the original PNG when further editing or another export may be needed.
