How to Convert HEIC to JPEG2000

HEIC and JPEG2000 both improve on older compression methods, but they target different industries — HEIC is built for everyday consumer photography on Apple devices, while JPEG2000 (.jp2) is mainly used in medical imaging, satellite photography, and archival systems that specifically rely on its wavelet-based compression and progressive decoding features. Converting an iPhone photo from HEIC to JPEG2000 is relevant when that photo needs to enter a workflow built around JPEG2000 specifically, such as certain archival or scientific imaging pipelines.

This is a less common conversion in everyday use, since most people moving photos off an iPhone need JPG or PNG rather than JPEG2000, but it remains useful for the specific systems that require it.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single HEIC file.
3. Drag your HEIC file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to HEIC and the "To" format to JPEG2000.
5. Click Convert. JP2 files are written to the output folder, fully offline.
