Where does the crop land on YOUR art?
Every platform crops differently, and the crop decides whether your title survives. Drop the image, flip through the frames, and export the versions that keep what matters.
Nothing is uploaded — your audio never leaves your device.
Drag inside any frame to reposition its crop. Each download exports at the exact target size.
Right-sized posts are craft. A release kit is a system.

Platforms don't resize your art — they crop it
The quiet assumption that ruins release posts: "the platform will fit my image." It won't. It will fill its frame and amputate whatever doesn't fit — which is how a square cover posted to a story loses its title to the top crop, and a wide banner decapitates the artist photo it was built around. The math is unforgiving: a 1:1 cover shown in a 9:16 story keeps barely a third of its width. Whether that surviving third contains your hook or dead space is decided by where the crop lands — and where the crop lands is decided by you, or by nobody.
This checker makes the decision visible before anyone else sees it. Drop the art once and it renders inside every working frame — 1080×1080 square, the 1080×1350 portrait that earns a quarter more feed height on Instagram, the 1080×1920 story, the 1200×630 link-preview landscape, the 1500×500 header strip. Every preview is live: drag the image inside a frame and the crop follows, clamped so you can't drag past the edges. When a frame looks right, its download button exports a real file at the exact target resolution, high-quality JPEG, named by platform so the upload run is mechanical. Or take the whole set as one ZIP.
The craft rule underneath: compose for the tightest crop you'll actually post. If the title survives the story frame, it survives everything wider. And when the source image is smaller than a target frame, the tool says so instead of silently upscaling — soft art with a warning beats soft art discovered in the feed.
Frequently asked questions
What image sizes do platforms want?
The working set: 1080×1080 square (feed universal), 1080×1350 portrait 4:5 (more screen on IG feeds), 1080×1920 story/reel 9:16, and wide banners around 1500×500 for headers. The checker previews your image in each and exports centered crops you can nudge.
Why does 4:5 beat square on Instagram feeds?
It's simply taller — a 4:5 post occupies about 25% more screen while scrolling, which is free attention. The crop preview shows whether your art survives the extra height.
Can I move the crop window?
Yes — drag the image inside any frame before exporting. Centered is the default; your subject's position is the decision.
What format do the exports use?
High-quality JPEG at each target size, named by platform and ratio so the upload step is mindless.
