Mosaico: Photo Collage

Pick 2 to 9 photos and get a single, post-ready image — framed around faces, sized for the feed, saved straight to your library.

Mosaico does one thing: it turns 2 to 9 photos into one beautiful image, ready to post.

No more building montages in the Stories grid and fishing them out of your camera roll — cropped wrong for the feed. Mosaico works in the right format from the start, and your montage stays editable forever.

HOW IT WORKS • Pick 2–9 photos — they land in a finished montage instantly • 33 arrangements, filtered to your photo count • Drag any line to resize photos against each other • Hold a photo to pick it up and swap it; drag or pinch inside to reframe • Smart framing centers on faces — or whatever draws the eye — automatically, on your device • White, black, any color, or a soft blur of your first photo behind the grid • Share anywhere right from the export screen

THE RIGHT FORMATS • Portrait 4:5 — the tallest the feed shows without cropping • Square 1:1 — the classic • Story 9:16 — full screen

Everything exports at 2160 px wide — double what Instagram serves, so what survives their compression is as good as it gets. Good enough to print, too.

YOUR MONTAGES STAY ALIVE Every montage is saved as an editable document, not a flat image. Come back next week, swap a photo, switch the layout, re-export as a Story — no starting over. A green dot marks the ones you've already exported.

PRIVATE BY DESIGN Mosaico never reads your photo library. The system picker hands it only the photos you choose, face detection happens entirely on your device, and the only thing it ever writes is the finished image you export. No account. No tracking. No network.

Made for people who post with care.
