Convert iPhone HEIC photos for listings
HEIC is what an iPhone actually writes, and a lot of tools handle it badly, especially rotation.
Why portrait photos arrive sideways
A camera sensor is a fixed rectangle. It does not turn when you do; it records which way up it was and leaves that to be applied later. In HEIC that instruction usually lives in the file’s container rather than in EXIF, and software that reads the wrong one, or both, rotates the photograph wrongly.
Applying exactly one rotation
PrepShot checks which of the two a file actually carries and applies one of them. Applying both is a real failure mode: the photograph arrives at 180 degrees, and it is easy to reach by combining two libraries that each behave correctly on their own.
Not just conversion
The same pass resizes, whitens the background, frames the product and names the file for whichever marketplaces you chose. Converting is the least interesting part of getting an iPhone photograph onto a listing.
Everything else too
JPEG, PNG, WebP, AVIF and TIFF are read as well, so a folder mixing a phone, a camera and a scanner needs no sorting first.
