Image to WebP Converter & Compressor

Why image size matters

Images are usually the heaviest part of a web page. Large images slow down loading, especially on mobile connections, and visitors leave pages that feel slow. Page speed is also part of how search engines judge the experience of a page, and a big hero image is often the element that decides how quickly the main content appears. Making images smaller is one of the simplest ways to speed up a site.

Compare before you download

After conversion, a slider lets you drag across the picture to compare the original on the left with the converted version on the right. Zoom in to 100% or 200% to check fine detail such as text, edges and skin tones. If you see artifacts, raise the quality a little. If you cannot see any difference, try lowering it to save more space.

What WebP is

WebP is an image format created for the web. It can store photos, graphics and images with transparency, and it usually produces smaller files than JPEG or PNG at a similar level of quality. All current major browsers can display it, which is why it is now a common choice for websites.

How to get the best results

• Resize first. There is no point in serving a 4000 pixel wide photo in a 800 pixel wide column. Use the maximum width option to match the size at which the image is shown, or up to twice that for sharp display on high-resolution screens.
• Choose a sensible quality. Start around 80 for photos and compare the result with the original. Lower it until you notice a difference, then step back a little.
• Keep the original when it does not help. Small or already optimised files may not shrink. The tool flags these.
• Use clear file names and alt text. A name like web-design-agency-team.webp and a short description in the alt attribute help both accessibility and image search.

How to use WebP on your site

Upload the converted files to your site and reference them in your HTML. To keep a fallback for very old browsers, wrap the image in a picture element. Always set the width and height so the page does not jump while the image loads, and lazy-load images that are below the first screen.

<picture>
      <source srcset="photo.webp" type="image/webp">
      <img src="photo.jpg" alt="Describe the image"
           width="1200" height="800" loading="lazy">
    </picture>

On WordPress, many themes and plugins can serve WebP automatically. You can also upload files converted here directly to the media library.

Removing the background first

If a product or portrait photo has a distracting background, cut it out with our Background Remover before you convert it. A transparent PNG from there can be turned into a small transparent WebP here, which is ideal for logos, team photos and product images.

Privacy and limits

The converter runs entirely in your browser, so your images are never uploaded. Very large images use a lot of memory while they are processed, so if your browser slows down, convert fewer files at a time. Animated GIFs are converted to a still image.
