How to convert PNG to WebP

  1. Choose a PNG

    Select one .png image up to 50 MB.

  2. Convert to WebP

    Novaxera re-encodes the PNG as WebP on its server, keeping transparency.

  3. Download the WebP

    Save the file; the server copy is deleted automatically within 60 minutes.

How Novaxera's PNG to WebP works

Novaxera's PNG to WebP converter decodes the PNG on its server and re-encodes it as WebP with the encoder's standard quality settings. WebP supports transparency, so transparent backgrounds stay transparent. That is the key difference from converting PNG to JPG, which fills transparent areas with white.

PNG is lossless and often produces large files, especially for photos and big screenshots. WebP usually gives a smaller file, which helps web pages load faster; the saving depends on the image. All current major browsers display WebP. The PNG upload is deleted when conversion finishes, and the WebP is removed automatically within 60 minutes.

Why use Novaxera's PNG to WebP

Transparency kept

Logos, icons and cut-outs keep their transparent background.

Usually lighter than PNG

WebP typically needs fewer bytes than the PNG, depending on the image.

Same dimensions

Width and height are never changed.

Web-ready

WebP is displayed by all current major browsers.

Common use cases

Transparent product cut-outs

Convert transparent PNG product images to WebP for a lighter online store without losing the cut-out.

Website logos and hero graphics

Shrink large PNG graphics for faster page loads while keeping transparency.

Large screenshots on blogs

Convert heavy PNG screenshots to WebP before publishing tutorials or documentation.

Limitations to know

  • Some older desktop software can't open WebP; keep the PNG for those uses, or convert back with WebP to PNG.
  • Results depend on the file: a small, simple PNG may shrink only a little.
  • There is no quality slider, resize option or batch mode; one PNG is converted per upload.

Tips for better results

  • For a transparent product photo, cut it out with Remove Background, then convert the PNG to WebP for your site.
  • If you don't need transparency and want broad compatibility, PNG to JPG is the alternative.
  • Keep the original PNG as the master; Compress Image can optimize it losslessly if you must stay in PNG.
