WebP output
A smaller WebP copy that keeps the transparent areas.
29 KB · WebPPNG to WebP
Create a web-ready WebP copy of a PNG, keep its transparent background, and compare quality with file size before publishing.
Your images are processed locally in your browser. They are never uploaded to a server.

Keep transparency in a web-ready copy
These real files show the same transparent artwork as PNG and as browser-generated WebP at the default quality. Results vary with image content.
Use WebP when the destination supports it
WebP often reduces the size of PNG artwork, but keep PNG when a workflow explicitly requires that format.
Convert to WebP when
- Your website or app accepts WebP images.
- You want a lighter copy while retaining transparent areas.
- You can keep the PNG source for editing and compatibility.
Keep the PNG when
- An upload form or design workflow specifically requires PNG.
- You need lossless source pixels for continued editing.
- You are unsure whether the receiving service supports WebP.
What changes during conversion
The pixel dimensions stay the same. WebP quality controls how strongly the visible image is encoded, while the alpha channel remains transparent.
Transparency stays transparent
No background color is needed because both PNG and WebP support alpha transparency.
File size often falls
Transparent illustrations and interface assets can become much smaller, but results depend on the source.
Keep the source PNG
Retain it when you may need lossless editing or PNG-only compatibility later.
