Crop a render to a ratio without guessing
Pick the ratio the slide, the post or the frame needs, type the image size, and get the crop that fits and what it loses.
Framing for where the image goes
Every surface has its ratio: a slide is 16:9, a social post is 4:5 or 1:1, a story is 9:16, a print is whatever the paper is. A render made for one rarely fits another without a crop.
The planner gives the largest frame at the target ratio inside the image, so the crop keeps as much as possible, and shows what is lost so you can decide where to center it.
When the framing matters, render again at the right ratio instead of cropping. Rendair apps output straight to these ratios, with the whole composition made for the frame.
