How to convert HEIC to JP2:
1. Click the "Choose Files" button to select multiple files on your computer or click the "URL" button to choose an online file from URL, Google Drive or Dropbox. Image file size can be up to 200M. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.
2. Set target image format, image quality and image size. You can use the original image size or select the "Change width and height" option and enter a custom image size. The format is [width]x[height], for example: 1920x1080. The image quality option only works on a few image formats such as JPG, WEBP or AVIF. 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, SVG, etc.
3. Click the "Convert Now!" button to start batch conversion. It will automatically retry conversion on another server if one fails, 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 cloud storage services such as Google Drive or Dropbox.
HEIC vs JP2:
| Name | HEIC | JP2 |
| Full name | High Efficiency Image File Format | JPEG 2000 |
| File extension | .heic | .jp2, .j2k, .jpf, .jpx, .jpm, .mj2 |
| MIME | image/heic | image/jp2 |
| Developed by | Moving Picture Experts Group (MPEG) | Joint Photographic Experts Group |
| Type of format | Image Container Format | Graphics file format |
| Introduction | As HEIC is a container format, it can contain still images and image sequences (where a file contains more than one single image) that are coded in different formats. Currently, these include HEVC and H.264/MPEG-4 AVC (and JPEG for thumbnail/secondary images), though other coding formats may be added in the future. The main filename extension is .heic (for HEVC codec). | 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 | In Apple's implementation, for single images they have chosen the latter .heic filename extension (.heics for image sequence files) as the only one they will produce for photos, which indicates clearly that it went through HEVC encoding. | 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. |
