What is PNG to WebP conversion?

PNG is reliable and lossless, but large PNG assets can slow a website or application. WebP supports both efficient compression and alpha transparency, so it is a practical delivery format for interface graphics, product images and illustrations.

This conversion keeps the original width, height and transparent pixels while creating a high-quality WebP copy. Private EXIF and text chunks are discarded. The exact size reduction depends on the amount of detail, noise and transparency in the source.

When should I use it?

  • Reduce the transfer size of transparent website graphics.
  • Prepare PNG product images for a modern storefront or CMS.
  • Make a smaller web copy while keeping the lossless PNG as the master file.

Frequently asked questions

Does WebP support transparency?

Yes. Transparent PNG pixels remain transparent in the WebP output.

Is WebP lossless?

WebP supports both modes. This converter uses high-quality lossy encoding for a useful size reduction while retaining alpha.

Should I delete my original PNG?

Keep the PNG if it is your editable master. Use the WebP as a delivery copy for supported browsers and apps.
