How to Convert Multiple HEIF Images to JP2?
1. Download and Install reaConverter
Download reaConverter and install it in seconds. The setup is straightforward — no complex configuration, no extra software required. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your HEIF files
Load your HEIF files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Select HEIFs from a folder or drag-and-drop them directly into the reaConverter window.
3. Select JP2 as output format
Choose JP2 for output and set your save location. reaConverter lets you customize quality and apply edits before conversion.
4. Start HEIF to JP2 conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.
After processing, find all your new .jp2 files in the output location. The log shows details for each conversion.
HEIF to JP2: what to expect from the conversion
HEIF and JP2 both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it. One HEIF file can hold several pages or frames, while JP2 holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
