How to convert PNG to WebP
Drop your PNG files above, or click to pick them. Each one is decoded and re-saved as WebP on your own device; nothing is uploaded, so there is no waiting for a server and no size limit beyond your computer's memory. Download files one by one or all at once. Batch conversion of dozens of files works the same way.
About PNG
PNG keeps every pixel exactly and supports transparency, which makes it larger, especially for photos.
About WebP
WebP is Google's web format: 25–35% smaller than JPG at the same quality and supports transparency, but some older apps and Windows tools cannot open it.
Quality setting
WebP is a lossy format, so a quality level controls the trade-off between file size and detail. 80–90% is visually identical to the original for photos; 60–70% halves the size again with slight softening. The before/after view lets you drag across the image and judge for yourself before downloading.
