How to convert WEBP to JP2 offline

Choose local WEBP image files, choose "JP2" as 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 try to use canvas in web browser to convert images first. The image format depends on whether your current web browser supports. For example: the latest Chrome browser supports AVIF images while some old versions don't. Then the offline converter will try to use JavaScript to convert images if your current web browser doesn't support the image format.

Introduction	WebP is an image format employing both lossy and lossless compression. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP-related software is released under a BSD license.	JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.
