What does PNG to WebP Converter do?

Convert PNG images to WebP with the alpha channel intact. WebP handles transparency like PNG but compresses far better, so logos, icons and UI graphics often shrink by 60% or more without any visible change.

Frequently Asked Questions

Does WebP keep PNG transparency?

Yes. WebP supports a full 8-bit alpha channel, exactly like PNG, so semi-transparent edges and drop shadows survive the conversion intact.

How much smaller will my PNG become?

Commonly 50–80% smaller for UI graphics and icons at high quality. Photographic PNGs can shrink by well over 90% because they were never suited to PNG in the first place.

Is WebP lossless like PNG?

It can be. WebP has both a lossless and a lossy mode. Browser encoders expose the lossy mode with a quality setting; at 95–100% the difference from the PNG is imperceptible while the file stays much smaller.

Should I convert all my site images to WebP?

It is usually worthwhile for photos and graphics. Keep SVG for logos and icons that are already vector — SVG scales perfectly and is often smaller still.
