Templates & auto layout

Auto layout picks a near-square grid that best fits your photo count. Prefer a specific style? Choose a curated template (e.g., 2-up horizontal, 3: big + two, 2×2 grid, 3×3 grid, magazine, mosaic). Each template uses clean spacing, balanced proportions, and rounded corners for a polished look.

Social size presets

  • Square — 1080 × 1080 (Instagram feed)
  • Portrait — 1080 × 1350 (Instagram portrait)
  • Landscape — 1920 × 1080 (HD)
  • Link preview — 1200 × 628 (Open Graph / social link)
  • Story / Reel — 1080 × 1920 (vertical)

Tips

  • Use Cover for edge-to-edge tiles; switch to Contain to keep full images without cropping.
  • Big canvases (e.g., posters) work best on desktop with plenty of RAM and a modern browser.
  • For web sharing, try WebP at 80–90% quality for smaller files.
  • Captions are optional—keep them short and high-contrast photos will remain readable thanks to the subtle backdrop.

Privacy

Your photos never leave your device. Everything is computed locally in your browser using HTML Canvas.
