Technical note

HEIC to JP2: what carries over and what does not

HEIC 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 HEIC 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.

My son sends me HEIC photos from his phone, and I can't view them on my old laptop. reaConverter fixed that in two clicks. Now I have JPEGs that open anywhere. It's so easy even I can do it – and I'm not tech‑savvy at all!

As a wedding photographer, I receive HEIC images from guests all the time. reaConverter converts them to JPEG with perfect colour accuracy – no weird tints or compression artifacts. It even preserves the original timestamps. This tool is a lifesaver during peak season.
