Why PNG to WebP helps your site

Images are usually the heaviest part of a page, and page weight affects speed and how well the page does in search. WebP gives the same look as PNG in a noticeably smaller file, and it keeps transparent backgrounds.

All current browsers show WebP, so there is no longer a reason to keep serving large PNGs for logos, product shots and illustrations.

Good to know

  • 85% is the default: for most images the change is invisible and the file is much lighter. For logos with sharp edges, try 90% or more.
  • Transparency is kept, so cut-outs and logos work on any background.
  • If a tool you use does not accept WebP, convert it back with the WebP to PNG page.

Frequently asked questions

How much lighter is WebP than PNG?
It depends on the picture. Photos in PNG often shrink by well over half; flat graphics shrink less. Each result shows its own percentage, so you see the real figure for your file.
Does WebP keep transparency?
Yes. WebP supports a transparent background just like PNG, which is why it is the usual replacement for PNG on websites.
Can every browser and app open WebP?
Every current browser can. Some older desktop software and a few upload forms still cannot, and for those a JPG or PNG is the safe choice.
Are my images uploaded to a server?
No. The conversion happens in your browser with your device's own image engine. The files never leave your computer or phone, which also means there is no waiting for an upload.
Is there a limit, a watermark or a signup?
No signup, no watermark. You can convert up to 30 images at once, up to 60 MB each, and use the results for anything, including commercial work.
