How to convert PNG to WEBP

Step 01

Drop your PNG images into the box above. You can add multiple files at once.

Step 02

Adjust the quality slider if available — higher quality means larger files.

Step 03

Click Convert. Each image is processed in your browser using the canvas API.

If you uploaded multiple images, they're packaged into a ZIP and downloaded automatically.

Converting PNG to WebP gives you the best of both worlds for the web: WebP keeps PNG's transparency but produces a much smaller file. A heavy PNG logo or graphic with a transparent background can shrink dramatically as WebP while still dropping cleanly onto any coloured layout. The conversion runs in your browser with no upload, so your assets stay private while you optimise them.

Transparency, but lighter

PNG is the go-to for transparent graphics, but it is also bulky. WebP supports the same alpha transparency while compressing far more efficiently, so PNG to WebP is the natural optimisation for icons, logos and UI assets headed for a website.

Unlike PNG to JPG, you do not lose the transparent background here — WebP keeps it intact.

Lossless or lossy WebP

WebP can be lossless (like PNG) or lossy (like JPG). For flat graphics and sharp text, lossless WebP gives PNG-grade crispness at a smaller size. For photographic PNGs, lossy WebP shrinks them the most. This converter's defaults pick a sensible balance, and you can adjust quality to taste.

Either way, expect a substantially smaller file than the original PNG.

Frequently asked questions

Does PNG to WebP keep transparency?

Yes. WebP supports an alpha channel, so transparent areas of your PNG stay transparent in the WebP — unlike converting to JPG.

How much smaller will the WebP be?

It varies by image, but WebP is typically much lighter than PNG for the same content, often by half or more, especially for graphics and logos.

Is WebP good for websites?

Yes — it is one of the best formats for web images, combining small size with transparency support, and every modern browser displays it.

Are my PNGs uploaded?

No. PNG-to-WebP conversion is done locally in your browser, so files never leave your device.
