Drop in PNG or JPG images, choose a quality and get WebP files that are usually much smaller. The conversion happens inside your browser, so your images are never uploaded anywhere, and you can convert a whole folder at once.
Images are usually the heaviest thing on a web page. On a typical small business homepage the hero photo alone can be larger than all the text, code and fonts combined. Every extra kilobyte has to travel over a phone connection before the page looks finished, which is exactly what Google measures with Largest Contentful Paint.
WebP is an image format made by Google for the web. It compresses photos more efficiently than JPG and supports transparency like PNG, so one format covers both jobs. Swapping a 900 KB PNG hero for a 120 KB WebP is often the single biggest speed win on a small site.
Quality is a trade between file size and detail. For photos of people, food, rooms or products, 75 to 85 looks the same as the original to almost everyone. For screenshots, charts or images with small text, use 90 or above, because low quality creates blurry halos around sharp edges.
The best way to decide is to convert once, open the result at full size next to the original, and lower the quality until you can see a difference, then go one step back up.
Most website builders and content systems accept WebP uploads just like JPG. If you write HTML yourself, a normal img tag works: set width and height so the page does not jump while the image loads, add a descriptive alt text, and add loading="lazy" to images further down the page.
Sites built with We.Inc already serve optimised images, but converting your own photos before uploading still keeps your storage small and your pages quick.
Yes. It is free, needs no signup, and the conversion runs entirely in your browser using the built-in canvas. Your images are not uploaded to We.Inc or anyone else.
Every current version of Chrome, Edge, Firefox and Safari shows WebP images. Safari added support in version 14 (2020), so only very old devices cannot display them.
It depends on the image. Photos saved from PNG often shrink by 70 to 90 percent. Compared with a well-compressed JPG, a WebP at similar quality is typically 25 to 35 percent smaller. The tool shows the exact saving for each file.
Yes. Transparent areas in a PNG stay transparent in the WebP. JPG has no transparency, so JPG sources stay fully opaque.
Very small or already heavily optimised images can grow slightly when re-encoded. The tool flags this so you can keep the original for that file.
Yes. Use the free image compressor on We.Inc, which can save to JPG, PNG or WebP.
