Works in your browser. What you paste or upload is processed on your device.
Click Choose PNG images or drag them in, up to 30 at a time.
Leave Lossless off for photos and illustrations; turn it on for logos, icons and screenshots with text.
In lossy mode, adjust the quality slider while watching the size preview. Add a max width if the images are larger than your page needs.
Press Convert to WebP, then download the files one by one or as a ZIP.
PNG to WebP converts PNG files to WebP, a format that keeps transparency like PNG but stores images more efficiently. It is a common step when a website's logos, illustrations, product cut-outs and screenshots are slowing pages down.
You choose between two modes. Lossy WebP (the default, at 85% quality) gives the smallest files and suits photos, product images and illustrations with gradients. Lossless WebP keeps every solid pixel exactly as in the PNG (soft, semi-transparent edges can shift by one colour level out of 255, which you can't see), which is right for logos, icons, UI screenshots and anything with sharp text; lossless WebP files are typically smaller than the PNG, though by less than lossy files. Transparent and semi-transparent pixels are kept in both modes.
The tool shows the expected size of your first image before you convert, so you can compare lossy and lossless for free. If a PNG is already very small (a simple icon of a few kilobytes), WebP may save little or nothing, and the preview will show that. Images above about 16.7 megapixels are scaled down to fit the browser's canvas limit.
PNG is the default export from design tools and screenshots, but it is rarely the most efficient format to serve on a web page. Switching to WebP keeps the transparency your design needs while cutting page weight, and the lossless option means you don't have to accept blurry edges on a logo to get a smaller file.

Yes. WebP supports full transparency, including soft edges and shadows, in both lossy and lossless mode. The converted logo or cut-out sits on your page exactly as the PNG did.
Use lossless for logos, icons, diagrams and screenshots, where sharp edges and exact colours matter. Use lossy for photos, product shots and illustrations with gradients, where it gives much smaller files with no visible change at 80 to 90% quality.
Usually, but not always. Tiny icons and simple graphics are sometimes already as small as WebP can make them. The tool shows the expected size of your first image before you convert.
Yes, up to 30 files per batch, each up to 60 MB. All converted files can be downloaded together as a ZIP.
Yes. It works in Safari on iPhone and Chrome on Android. Large batches take longer on phones, so keep the tab open until the progress bar finishes.
No. The images are converted on your own device and never leave it. Our server only receives a usage count for the daily free run.
You get one free run of this tool per day without an account. After that, each run costs 5 credits from a free AI Rank Lab account (1 credit is 1 US cent). One run is one press of the Convert button, whether the batch has one image or 30.
Each one opens on its own page and works straight away, with no sign-up.
