About the Convert to WebP
This converter turns JPG, PNG and AVIF images into modern WebP files using your browser's built-in encoder. Set the quality slider, drop in one or many images, and download each converted WebP with its new, smaller file size shown next to the original.
WebP typically produces files 25–35% smaller than JPEG at the same visual quality, and it supports transparency like PNG at a fraction of the size. Every modern browser supports it, which is why Google's PageSpeed recommendations push sites to serve WebP.
Conversion happens completely locally — your images are never uploaded. That makes batch-converting a whole folder of product photos or blog images both fast and private.
Frequently asked questions
Is WebP better than JPEG?
For web use, almost always — WebP files are typically 25–35% smaller than JPEG at equivalent visual quality, and WebP also supports transparency and animation. JPEG's only remaining edge is universal support in very old software.
What quality setting should I use for WebP?
Quality 75–85 is the sweet spot for photographs — big savings with virtually invisible artifacts. Graphics with sharp edges and text look better at 85–95, while thumbnails can drop to 60–70 without anyone noticing.
Do all browsers support WebP?
Yes — Chrome, Firefox, Edge, Safari (since version 14 in 2020) and all modern mobile browsers display WebP natively. It is safe to serve WebP to your whole audience today.
Does converting PNG to WebP keep transparency?
Yes. WebP has a full alpha channel, so transparent areas in your PNG remain transparent after conversion — usually at a dramatically smaller file size than the original PNG.
Why do WebP images make my website faster?
Images are usually the heaviest assets on a page. Cutting each image by a third with WebP directly reduces bytes transferred, which improves Largest Contentful Paint and other Core Web Vitals that affect both user experience and SEO.
