How it works

WebP keeps the PNG’s transparency while usually cutting the file size substantially, which is its main advantage for the web. By default this uses WebP’s lossy encoder — excellent for photographic PNGs — and the quality slider tunes it. Very flat graphics with hard edges may prefer PNG’s exact lossless storage; for those, raising the quality avoids softened edges. The alpha channel is always preserved.

Convert PNG to WebP in your browser. WebP can be lossless like PNG but produces a smaller file, and it keeps transparency — so you get the same crisp graphic at a lighter weight, ideal for the web.

Why convert PNG to WebP?

WebP gives you a PNG-quality graphic at a much smaller size, and it keeps transparency. For logos, icons, screenshots, and illustrations on the web, that means the same crisp result loading faster. It is the single easiest swap for lightening heavy PNGs without redesigning anything.

Lossless vs lossy WebP

Choose lossless WebP to match your PNG pixel-for-pixel at a smaller size — ideal for sharp graphics and text. Choose lossy WebP for the smallest possible file when a tiny, invisible quality trade is acceptable, such as detailed illustrations. Either way, transparency is preserved.

How to convert an image

  1. 1Upload your PNG.
  2. 2Choose lossless WebP to match PNG exactly, or lossy for an even smaller file.
  3. 3Confirm transparency and edges look right in the preview.
  4. 4Download the WebP.

When to use PNG to WebP

  • Shrinking logos, icons, and screenshots for the web without losing sharpness.
  • Keeping transparency while cutting file size.
  • Serving lighter graphics to speed up a page.

Frequently asked questions

Does WebP keep PNG transparency?

Yes. WebP supports a full alpha channel, so transparent PNGs convert with their transparency intact.

Will it stay lossless?

It can. Choose lossless WebP for a pixel-perfect match to the PNG at a smaller size, or lossy WebP for the smallest file.

Why convert PNG to WebP at all?
