PNG to WebP can keep transparency

WebP supports transparent pixels, so transparent areas in a browser-readable PNG can remain transparent in the output. Check the preview before publishing or sharing the file.

Choose between file size and detail

WebP quality controls the balance between a compact file and visible detail. Keep the original PNG when you need the source's exact pixels or a copy for further edits.

  • Use WebP for websites and apps that support modern image delivery.
  • Use it for transparent graphics when a smaller download is useful.
  • Keep PNG for editing pipelines or destinations that require PNG specifically.

Limitations

  • WebP output may be lossy at lower quality settings, so keep the original PNG when exact pixels matter.
  • WebP support depends on the app or website where you use the output.
