How to convert DDS to WEBP offline

Choose local DDS image files, choose "WEBP" as the target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. File size can be up to 2GB.

This offline converter will first try to use the Canvas API in your web browser to convert images. The supported image formats depend on your current web browser. For example, the latest Chrome browser supports AVIF images while some older versions do not. The offline converter will then try to use JavaScript to convert the images if your current web browser doesn't support the image format. Use our online converter instead if this offline converter doesn't work in your web browser.
