Quick answer
Local Product collage tools are more private and work offline; online tools save installation but files leave your device. Product collages need consistent background/light and highlight selling points, not clutter.
Why it matters
Use local for sensitive files; online is fine for small temporary ones.
White/same-color backgrounds look professional.
Step by step
- Decide the use/ratio: social square, vertical Story or print.
- Pick 2-9 photos with clear subjects and consistent color/exposure.
- Choose layout/spacing so faces/subjects are not cropped.
- Export 1200px+ PNG/JPG and check edges/margins.
- Clear likeness/image rights and privacy before posting.
Common mistakes
- Nine mismatched color grades in one grid look chaotic.
- Zero gap leaves subjects touching/cropped at edges.
- Upscaling low-resolution photos makes them blurry.
- Using unlicensed people/photos for commercial promotion.
Checklist
- Ratio matches platform/print.
- Photo count fits the cells.
- Faces/subjects intact with sensible gaps.
- Resolution is sufficient, no compression artifacts.
- Likeness/image rights and privacy cleared.
Key facts
- White/same-color backgrounds look professional.
- One selling point per cell.
