How to Combine Images Into a Collage Online
Mood boards, Instagram carousels-as-single-image, and lookbook grids need multiple photos in one frame. FreeMake merge-images builds collages locally in your browser—pick a layout, arrange shots, export PNG or JPG without upload.
Upload multiple photos
Add variant colorways, lifestyle B-roll, or campaign teasers. Crop individual shots to consistent aspect ratios first if the layout cells are uniform squares.
Choose a collage layout template
Select grid patterns matching your social placement—2×2 for Feed squares, vertical stacks for Stories cover composites.
Arrange and preview composition
Drag images into cells; ensure hero SKU occupies the largest cell for shoppable posts. Keep text and logos out if mimicking marketplace-style clean grids.
Export and optimize for channel
Download PNG or JPG, then resize and compress to platform limits. For swipeable carousels, export separate cropped images instead of one collage.
Why Collages Help Social and B2B Sales
One composite tells a color story faster than nine single posts. Local collage building keeps embargoed collections off Canva cloud projects.
Show variant ranges in one asset
Apparel sellers display six colors in a grid for wholesale buyers—one attachment instead of a heavy ZIP of singles.
Build lookbooks without InDesign
Merge lifestyle and product shots for email hero graphics when design team bandwidth is tight before seasonal launch.
Private local compositing
Unreleased collaboration SKUs stay on-device—no cloud collage SaaS indexing your masters.

Collage Formats and Channel Tips
Export JPG for photo-heavy collages and PNG when sharp text overlays matter. Final pixel dimensions depend on layout—resize to 1080×1080 or 1080×1350 for Instagram after export.
Amazon main images must be single-product heroes—do not upload collages as primary listing slots. Use collages for social, email, and wholesale decks only.
- JPG — photo collages and email headers
- PNG — sharper edges for branded grids
- Instagram — resize after export to Feed specs
- Carousels — use crop tool for separate slides vs one collage
