Steps:

1. Click "Choose Files" button to select multiple files on your computer. You can also click the dropdown button to choose online file from URL, Google Drive or Dropbox. Image file size can be up to 200M.

2. Set target image format, image quality and image size. You can use the original image size or select "Change width and height" option and enter customized image size. The format is [width]x[height], for example: 1920x1080. Image quality option only works on a few image formats such as JPG, WEBP or AVIF etc. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM or SVG etc.

3. Click "Convert Now!" button to start batch conversion. It will automatically retry another server if one failed, please be patient while converting. The output files will be listed in the "Conversion Results" section. Click icon to show file QR code or save file to online storage services such as Google Drive or Dropbox.

Introduction Digital Negative (DNG) is a patented, open lossless raw image format written by Adobe used for digital photography. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG. DNG is based on the TIFF/EP standard format, and mandates significant use of metadata. Use of the file format is royalty-free. 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.
Technical details A DNG file always contains data for one main image, plus metadata, and optionally contains at least one JPEG preview. It normally has the extension "dng" or "DNG". DNG conforms to TIFF/EP and is structured according to TIFF. DNG supports various formats of metadata, (including Exif metadata, XMP metadata, IPTC metadata), and specifies a set of mandated metadata. JPEG 2000 code streams are regions of interest that offer several mechanisms to support spatial random access or region of interest access at varying degrees of granularity. It is possible to store different parts of the same picture using different quality.
