12 Photo Collage Maker - 7+ Layouts, Free Online

Calendar Year Template: One Photo Per Month

Pi7 makes a 12 photo collage online with 7+ layouts including the 12-Months Scrapbook - a polaroid-on-cream-paper year-in-review that lays one photo per month, January through December, behind a script "12 Months" headline. Free, browser-based, exports at print-ready 4K. No signup, no upload.

The 12-Months Scrapbook is the layout you reach for when twelve photos have natural rhythm - twelve months of a year, twelve frames of a friend group across a season, twelve weekly highlights stretched out. Drag any polaroid to reorder months; tap the script "12 Months" headline to change it to "2026" or "Our Year" or any phrase in the same italic serif. For everything else, the 3x4 grid, 4x3 vertical, 2x6 wide banner, bento spread, mosaic, and editorial spreads cover catalogue-style, Story-format, newsletter-header, and magazine layouts.

Why Twelve Hits the Sweet Spot

Twelve is the count where a single image still reads as a list - twelve months, twelve highlights, twelve people in a friend group, twelve days of a trip. Each photo gets enough space to be its own moment, but the whole image still hangs together as one composition. A 6-photo grid feels thin for a year recap; a 30-photo grid blurs the individual shots.

Pick the 12-photo grid for grouped storytelling. For tighter highlight reels, the 5 photo collage maker covers short-format counts, and our triptych layouts handle three-photo arrangements with eight purpose-built templates. Pi7's milestone collage maker ships with 5x6 grids and themed birthday templates for 30th birthdays, anniversaries, and big trip recaps. For multi-generational family stories with grandparents, parents, and kids in one frame, the family photo collage maker ships with a tiered family tree layout and reunion grids. For layered scrapbook compositions where photos overlap and tilt, the picture montage maker ships with mood-led templates.

Where twelve photos in one frame earn their keep.

Square, Vertical, or Wide Banner - Pick by Channel

12 photos in one frame work cleanly at standard share sizes. For Instagram feed, the 1080x1080 square gives each of the 12 photos roughly 270x270px - readable on any phone. For Stories and WhatsApp status, the 1080x1920 vertical works best with the 4x3 layout (360x480px per cell). For newsletter headers and email signatures, the 2400x1200 wide banner with the 2x6 layout gives each photo a 400x600 hero cell.

Pi7's editor includes presets for all of these. Pick the share destination, the canvas auto-resizes, and the layout reflows to keep each of the 12 photos at the right scale. No manual aspect-ratio math.

Built for Family Albums, Not Stock Photos

Privacy is not an afterthought here - the whole tool is engineered around it. The photos that go into a 12 photo collage are usually personal: a year of family moments, a baby's first twelve months, a friend group's twelve favorites. We do not think those should pass through a third party's server just so you can stitch them together. So they do not.

Most online collage tools work by uploading your 12 photos to a server, processing them in the cloud, then handing back the finished image. Pi7 does the opposite. Every photo you drop in is read locally by JavaScript and rendered to a canvas inside your own browser. The pixels never travel - not to us, not to a CDN, not to a third-party processor.

No Account, No Upload, No Watermark

No signup, no email, no account creation, no waiting on an upload bar. Open the tab, build the collage, export the image, close the tab - and the session is gone. There is no copy of your 12 photos on a server somewhere being indexed, sold to model training, or sitting in an archived backup.

The practical knock-on benefits: it is fast (no upload time even for high-resolution phone photos), it works offline once the page is loaded, there is no rate limit because there is no shared backend to throttle, and no watermark on the export because there is no premium tier to upsell into.
