Perfectly centered images. Every time. Outer trims the empty space from your images and re-centres the subject with consistent padding. Drop in a folder of inconsistent files; get back perfectly framed exports — all the same size, all with the subject dead-centre. HOW IT WORKS Outer detects the subject in each image (on a transparent background or a solid colour), trims away every pixel that isn't part of it, then adds an even border of your chosen padding. Every output is the same shape with the subject centred — by its pixel edges, or optically by its visual weight, with a Balance slider and manual nudges when you want the final say. For hundreds or thousands of files — product photos, icon sets, scans, AI art — that means consistent dimensions, consistent margins and zero manual cropping. FORMATS Reads PNG, JPEG, TIFF, HEIC, WebP and SVG. Writes PNG, JPEG, TIFF, HEIC and AVIF — and SVG output stays vector. Convert between formats and resize in the same pass: by percentage, by width or height, or to exact dimensions with the subject fitted, never stretched. WHO IT'S FOR E-COMMERCE Every product photo at identical dimensions, perfectly centred, ready for clean grids on Shopify, Etsy, Amazon or your own storefront. Two hundred photos become two hundred uniformly framed exports in one run. GAME ASSETS Drop a sprite sheet — Multi Mode detects every shape and exports each as its own trimmed file, with sparks and drips attached to their subject. Rebuild the frames as a tidy sheet, step through them in Animate with onion skinning, nudge any frame, and export as GIF, APNG, MP4 or Lottie with a JSON atlas. Works on PNG, JPEG and vector SVG sheets. WEB ASSETS Thumbnails, hero images and blog graphics at uniform dimensions. Apply a preset to a folder and update a whole site's imagery in one step. AI ART, 3D RENDERS, ICONS, STICKERS, SCANS Tidy the stray padding of DALL-E, Midjourney and Stable Diffusion outputs into a coherent set. Trim Blender, Cinema 4D or Maya renders without re-rendering. Generate every icon size from a master. Trim sticker packs tight for iMessage, Telegram, Discord and Line. Find the artwork inside each scan and drop the white margins. SMARTER CROPPING TOOLS - Optical centring — by pixel edges, by Mass, or by Contrast (where the eye actually lands). A sword tip or a long tail no longer drags a character off-centre. - Background removal — key by colour distance (detected, or a colour you pick), keep only shapes above a size, or lift the subject with macOS's on-device Subject detection. Edges are matted, not hard-cut: no light halo, and pencil strokes stay soft. - Regions tool — click an enclosed gap to remove it, brush away leftovers, ⌥-brush to restore. - Drop detached pieces — remove specks, sparks and stray bits, or keep only the largest shape. - Donut-aware — subjects with holes (letter O, donuts, cogwheels) keep their interior intact. - Export background colour — flatten onto a swatch, a hex value or a saved colour. - Aspect ratio cropping — 1:1, 4:5, 16:9, 3:2, 2:3, A4, Letter and more. - Presets — save settings, organise them into categories, share them as JSON. - Sample images — 38 bundled files to try every feature on, from Help ▸ Open Sample Images.
