How to use PNG to WebP

  1. Add PNG files — transparency is kept automatically.

  2. Choose the WebP quality.

  3. Click Convert to WebP.

  4. Check the size savings and download.

About this tool

Unlike JPG, WebP supports an alpha channel, so logos, icons and UI screenshots with transparent backgrounds convert cleanly. For graphics with large flat areas the size reduction over PNG is often dramatic. The quality setting applies lossy WebP compression; at 90%+ the result is visually indistinguishable for most graphics while still much smaller than the PNG.

This makes WebP the better default for any transparent graphic destined for the web — a logo, an icon set, or a screenshot with rounded corners — since you keep the exact transparency behavior of PNG without paying its file-size cost.

Common ways people use this

  • Shrinking a logo or icon with a transparent background before adding it to a website
  • Reducing the size of UI screenshots that include transparent or rounded-corner elements
  • Preparing a set of transparent graphics for an app that benefits from smaller asset sizes

Tips for better results

  • Use 90% or higher quality for logos and icons — the size saving over PNG is already large even at high quality settings.
  • Check the preview closely if the graphic has fine text or thin lines, since lossy compression can very slightly soften sharp edges.

Frequently asked questions

Is transparency preserved?
Yes. WebP supports full alpha transparency, so transparent PNG areas stay transparent after conversion.
Why is WebP so much smaller than my PNG?
PNG compression is lossless and relatively simple. WebP can apply modern lossy compression even to graphics with transparency, which shrinks files substantially with little visible change.
Should I use WebP or PNG for my website?
Use WebP for anything served to browsers — it is smaller and universally supported. Keep PNG for editing masters or when a workflow specifically requires it.
Will fine details like small text in a screenshot stay sharp?
At 90%+ quality, yes, for the vast majority of graphics. If you notice softening on very fine text, try a higher quality setting or compare against the original at full zoom.
Can I batch convert multiple PNGs to WebP?
Yes, add several PNG files together and each is converted with the same settings, ready to download.
