Extract text from JPEG 2000 images (JPG2)
To convert JPG2 images to another format, you need Adobe Photoshop or other Raster Image software.
To convert other file formats to the "JPEG 2000 Image" file type, you need software like Adobe Photoshop or a similar tool.
A .jpg2 file is a raster image encoded using the JPEG 2000 standard. Developed by the Joint Photographic Experts Group, it uses discrete wavelet transform (DWT) technology. This offers both lossless and lossy compression, resulting in sharper images at smaller file sizes compared to standard JPG files. It is primarily used in professional archiving, medical imaging (DICOM), and digital cinema packages.
You can open .jpg2 files using advanced image editors like Adobe Photoshop or dedicated viewers like IrfanView. Native support is also built into macOS via Apple Preview.
Users almost always need to convert this format because it suffers from a major disadvantage: terrible universal compatibility. Most major web browsers, including Google Chrome and Mozilla Firefox, do not support JPEG 2000 natively due to complex decoding requirements and historical patent concerns. If you send a .jpg2 file to an average user or upload it to a basic website, it will simply fail to display.
The best target formats for conversion are JPG, PNG, or WEBP. Use JPG for universal photo compatibility, WEBP for modern web publishing, and PNG if you need to retain lossless quality and transparency. Be aware that standard JPEG conversion will permanently strip the advanced wavelet multi-resolution scaling.
Because JPEG 2000 relies on heavy computational algorithms and specific encoding profiles, it is often difficult for standard online tools to convert. Often, only the original professional software can properly read or export the image data. If our analysis detects a supported underlying image stream, viewing or conversion to standard formats may still be possible.
Convert.Guru analyzes your JPG2 file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JPG2 converter.
