Screenshot Toolkit

Mac App Store Screenshot Resizer

Mac App Store listings use Retina screenshots in landscape. This tool resizes your captures to every accepted Mac resolution — 2880×1800, 2560×1600, 1440×900 and 1280×800 — with crisp, high-quality scaling.

Because Mac screenshots are landscape and high-resolution, downscaling quality matters. The toolkit uses pica's Lanczos resampling on an OffscreenCanvas so text and UI stay sharp instead of muddy.

Pick Fit to preserve your exact framing with optional padding, or Fill to edge-to-edge crop. Everything is processed on your Mac locally — ideal for unreleased apps you don't want leaving your machine.

Mac screenshot FAQ

What size are Mac App Store screenshots?

Apple accepts 2880×1800, 2560×1600, 1440×900 and 1280×800, all in landscape. 2880×1800 is the most common Retina choice.

Will resizing keep my Mac screenshots sharp?

Yes — high-quality pica resampling preserves detail far better than a plain canvas downscale.

Does it work offline on my Mac?

Yes. After the first visit it works offline as a PWA, and no image ever leaves your computer.
