Why convert PNG to WebP
PNG is great for graphics, but large PNG photos and illustrations slow websites down. WebP supports transparency like PNG while compressing far more efficiently, so logos, product cut-outs and illustrations get noticeably smaller without losing their transparent background. All current versions of Chrome, Edge, Firefox and Safari display WebP.
Quality tips:
- 90%: close to the original, good for detailed graphics.
- 75–85%: the usual choice for website images.
- For screenshots full of small text, check the result; if edges look soft, raise the quality or keep the PNG.
Everything runs in your browser, so your images are not uploaded. Drop a whole folder of PNG files and download every WebP in one ZIP. For photos that started as JPG, use JPG to WebP; to go back, use WebP to PNG.
Where WebP helps most
The biggest savings usually come from large hero images, product photos with transparent backgrounds and detailed illustrations. For the smallest files, resize the image to the size it is actually displayed at before converting. Most site builders accept WebP uploads, and in your own HTML a normal image tag works in all current browsers. Keep the original PNG files as your editable masters.
Frequently asked questions
Does WebP keep transparency?
Yes. Transparent areas of the PNG stay transparent in the WebP file.
How much smaller will my images be?
It depends on the image. Photos and illustrations often shrink a lot; simple flat graphics sometimes only a little.
Is the conversion private?
Yes. It happens in your browser and nothing is uploaded.
