Photo collage maker

A collage combines multiple photos into one composite image. People make them constantly — for social posts, family albums, event recaps, before/after comparisons, product showcases. Most collage tools come with watermarks or paid template tiers.

Ours won't. You'll get grid layouts (2×2, 3×3, 4×4, customizable), mosaic templates (auto-arrange any number of photos), freeform positioning (drag photos anywhere), aspect-ratio export presets, and high-resolution output. All in your browser.

When you'll need this

Useful for:

• Social media recaps. One image summarizing a trip or event.
• Before-and-after comparisons. Show transformations side by side.
• Real estate listings. Multiple property views in one preview.
• Product showcases. Multiple angles or color variants in one image.
• Photo books and gifts. Preview of pages before printing.
• Mood boards. Aesthetic inspiration in one composite.

Output formats: JPG, PNG, or WebP. Aspect ratios: square (1:1), portrait (4:5, 9:16), landscape (16:9), or custom dimensions.
