PNG to WebP benefits

  • Transparency preserved

    WebP supports an alpha channel just like PNG, so logos and cut-out images keep their transparent background.

  • Big size savings

    PNG stores every pixel without loss. WebP’s compression usually shrinks photos and graphics stored as PNG dramatically.

  • Better for websites

    Replacing large PNG images with WebP is one of the quickest ways to make a page load faster.

PNG to WebP FAQ

Does WebP keep PNG transparency?

Yes. Transparent and semi-transparent areas stay transparent in the WebP file.

How much smaller is WebP than PNG?

It depends on the image. Photos saved as PNG often shrink by 70% or more; screenshots and flat graphics typically shrink by half or more. You’ll see the exact numbers after converting.

Will text in screenshots stay sharp?

At 85% quality or higher, text and thin lines stay crisp. If you notice soft edges around text, raise the quality slider and convert again.

Should I use WebP or PNG?

Use WebP for images shown on websites and apps. Keep PNG when you need lossless files for further editing, or for software that doesn’t open WebP.

Are my PNG files uploaded?
