Convert PNG to WebP
If PNG is on your site purely out of habit, WebP is the easy win: graphics and screenshots often drop 60–80% in size, transparency included. Every browser has rendered WebP since 2020, so the old fallback dance is no longer required.
Open converterHow to convert PNG to WebP
- 1
Open the PNG
Drop in the PNG you want to slim down — screenshots, graphics, and transparent logos all qualify, since WebP keeps the alpha channel intact.
- 2
Dial in the quality
Start the slider around 80–90. That's the range where screenshots and graphics stay visually faithful while shedding most of their PNG weight.

Download and keep your master
Click Convert & download; the saved-size readout shows your savings. Treat the WebP as the deliverable and hold on to the PNG as the original.
Why convert PNG to WebP?
-
Big, cheap savings: UI screenshots and graphics that weigh 1 MB as PNG often land under 300 KB as WebP.
-
Unlike JPG, WebP keeps your alpha channel, so transparent logos and cut-outs don't need flattening.
-
Smaller hero and product images directly improve LCP — the loading metric PageSpeed scores hammer hardest.
-
Chrome, Safari, Firefox, and Edge have all supported WebP since September 2020.
What actually happens to your file
The export here uses WebP's lossy mode with a quality slider, which is where the dramatic savings come from — at quality 80–90 the result is visually faithful for screenshots, graphics, and photos alike, at a fraction of PNG's weight. Because it is lossy, treat the PNG as your master and the WebP as the deliverable: don't delete the original, and don't run a WebP through repeated edit-export cycles. Transparency is preserved, including the soft, semi-transparent edges that GIF could never handle.
Frequently asked questions
Does WebP keep PNG transparency?
Yes, fully — including partial transparency like soft shadows and anti-aliased edges. That's the main reason to pick WebP over JPG when shrinking a PNG.
How much smaller will my file get?
It depends on the content, but screenshots and flat graphics commonly shrink 60–80%, and photographic PNGs even more. Move the quality slider while watching the preview to find your own floor.
Is there anywhere WebP still doesn't work?
All current browsers display it, and have since 2020. The stragglers are older desktop programs and a few strict upload forms — for those, keep a PNG or JPG copy around.
