JPG to WebP Converter Online

WebP is an image format developed by Google and first released in 2010. It was designed to reduce image file sizes while maintaining useful visual quality for websites. WebP supports lossy and lossless compression, transparency and animation, making it suitable for a wide range of web images.

JPG has been widely used for digital photographs since the early 1990s and remains one of the most common image formats. However, WebP can often produce a smaller file for a similar visual result. This is why many website owners convert JPG images to WebP before using them online.

Images are often one of the largest parts of a web page. A product page, portfolio or blog post with many photographs can quickly become heavy, especially for visitors using mobile connections. According to Google's WebP compression study, lossy WebP images were 25–34% smaller than JPEG images of comparable quality.

Smaller images can also help with website performance. Large images may contribute to slower loading and can affect metrics such as Largest Contentful Paint when they are used as prominent page content.

Converting the format is only one part of image optimization. For better performance, also consider resizing images to their actual display dimensions, using appropriate compression, lazy loading below-the-fold images and applying browser or server caching.

When You Should Keep JPG

WebP is useful for many websites, but JPG can still be the better choice for certain workflows. For example, you may want to keep JPG files for printing, older software or situations where WebP is not supported. It is a good idea to keep your original JPG files as backups and use WebP copies for your website.

Converting one image is simple with almost any tool. The process becomes more time-consuming when you have a product catalogue, photo collection or large blog archive. Uploading, converting and downloading every image individually can quickly become repetitive.

With this converter, you can add multiple JPG images at once, select Convert All and download the completed WebP files together as a ZIP. Because the conversion happens in your browser, performance depends on your device and the size of your images.

For hundreds of large camera images, working with smaller batches can help keep your browser responsive and reduce memory usage during conversion.

Start with the original. Every time a JPG is edited and re-saved, some image information may be lost. Converting the cleanest original copy you have usually gives better results.

Resize before you convert. If a 4000-pixel image is displayed inside an 800-pixel space, much of that extra resolution may be unnecessary. Resize the image to a suitable display size before converting it to WebP.

Compare the final file size. Many photographs become smaller after conversion, but results vary by image. If an already-compressed JPG barely changes in size, keeping the original may be perfectly reasonable.

WebP Browser and Platform Support

WebP images are supported by all major modern browsers, including Chrome, Edge, Firefox, Opera and Safari 14 or later on iPhone, iPad and Mac. WordPress has supported WebP uploads since version 5.8, while platforms such as Shopify and many image CDNs also support the format. For current browser support information, see Can I Use: WebP .
