- Click Convert to WebP and download the files or a ZIP.
Faster websites with WebP
PNG is excellent for quality but heavy for the web. Replacing PNG images with WebP is one of the easiest ways to make pages load faster, improve Largest Contentful Paint (a Core Web Vitals metric) and reduce bandwidth costs, all without changing how the images look. WebP is supported by Chrome, Edge, Firefox, Safari and every other modern browser, and by WordPress, Shopify and most site builders.
Keep transparency, lose the weight
Unlike JPG, WebP supports transparent backgrounds, so logos, product cut-outs and icons can be converted without adding a white box behind them. Test a few images at different quality settings to see where the size savings stop being worth it for your graphics.

How much will my site speed up?
Images are often more than half the weight of a web page. Replacing a 1.2 MB hero PNG with a 250 KB WebP saves almost a megabyte on every visit, which can take a full second off load times on mobile networks. Product grids and blog posts with many PNG images benefit the most. After converting, upload the WebP files and update your image links, or use your platform’s media library to replace the originals.
Lossy vs. lossless WebP
WebP can store images in two ways. Lossy WebP, used by this converter, gives the biggest savings and is ideal for photos and illustrations. At quality 95–100 the result is visually indistinguishable from the PNG for most graphics, including logos with text. If a WebP shows faint smudging around sharp edges, simply convert again with a higher quality.
Keep your originals
WebP is a delivery format. Keep the original PNG files as your editable masters, and convert copies for publishing. That way you can always re-export at a different quality or size later without losing detail, for example when a design changes or a new format such as AVIF becomes your preferred choice.
