Which social platforms are included in the generated kit?

The composer generates up to 13 assets covering Instagram, X (Twitter), LinkedIn, YouTube, and Facebook.

What is the difference between cover and contain fit modes?

Cover crops the master image to fill the target dimensions entirely, while contain scales the image within bounds and fills extra space with your selected background color.

Are safe-zone overlays included on the final exported files?

No. Safe-zone overlays appear only in the composer preview to help you verify design safety; exported assets remain clean.

What is included in the manifest.json file?

The manifest provides exact pixel dimensions, platform names, asset types, and safe-zone inset measurements for every generated file.

What file formats can I upload and export?

You can upload PNG, JPEG, WebP, AVIF, or TIFF master files and export the resulting asset kit as JPEG, PNG, or WebP.

Details

What this tool helps you do

Renders 13 assets across Instagram (1:1, 4:5, 3:4 grid-perfect — the 2025 grid standard, Story and Reel with their safe zones), X (1500×500 header with avatar overlay, 16:9 feed), LinkedIn (1584×396 personal banner with avatar zone, 1512×256 company cover per LinkedIn's current help page, 1.91:1 post), YouTube (1280×720 thumbnail with duration-badge zone, 2560×1440 banner with 1546×423 all-device safe area) and Facebook (1200×630 link card). Crops use sharp cover or contain with a custom background; overlays mark unsafe margins, avatar circles/rects and the duration badge. The ZIP contains full-resolution files plus a manifest.json with every dimension and safe-zone inset.
