JP2 to JPG: what to expect from the conversion

JP2 can carry an alpha channel and JPG cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page. JP2 carries 16 bits per channel and JPG carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end.

"I was stuck with 500+ BMP files from an old project – they were huge and unusable. reaConverter turned them all to JPEG in about 3 minutes. No quality loss, no hassle. I wish I had found this earlier instead of wasting hours with online converters."

"I run a small real estate agency, and we take hundreds of property photos in RAW. Converting them to JPEG for listings used to be a nightmare – until reaConverter. Now I just drop all CR2 files into the batch, set output to JPEG, and within minutes I have web-ready images. The quality is pristine, and the file sizes are perfect for our site. This tool literally pays for itself in time saved."
