Perfectly centered images. Every time.
Outer trims the empty space from your images and re-centers the subject with consistent padding. Built for batches of hundreds — game assets, app icons, store listings, anywhere alignment matters.
See it in action
Outer finds the edges, trims the empty space, and re-centers the subject.
Auto-center subjects
Trim the padding, add it back evenly, and your subject lands dead-center — every time, across every image.
Built for big batches
Drop a folder of a thousand images. Outer processes them in parallel with live progress and disk-backed caching.
Runs on your Mac
Native SwiftUI app. No uploads, no cloud — your images never leave your machine.
Smart trim threshold
Detects transparency or background color automatically. Adjust the threshold for tricky edges.
Resize and crop
Scale to a target size or crop to a fixed aspect ratio in the same pass. Output identical, predictable files.
PNG, JPEG, TIFF, WebP, SVG
Convert formats on export. SVGs stay vector — analyzed as pixels, written as scalable output.
Built for every batch
Anywhere you've got a folder of images that need to line up.
One tool. Every image.
Whether you're preparing game assets, exporting app icons, or tidying up a folder of screenshots, Outer handles the tedious part. Set a threshold, pick an output size, and let it run.
Coming soon to the Mac App Store
