Auto Square

Many amateur and professional photographers love the square format! Why? Not just because it fits Instagram perfectly, but also because it has some of the vintage atmosphere of old Polaroid photos and allows an improved composition of the image.

Applying the square format to a single image or to an entire folder is now easier than ever with reaConverter's latest edition. A new feature called Auto Square lets you do this is in no more than a few clicks.
