1) What is an online collage?

A collage combines multiple photos into a single image using a grid layout (2x2, 3x1, 3x3, etc.).

Use consistent aspect ratios, add subtle spacing, and export at platform-friendly sizes (e.g., 1080px width for Instagram).

Resize first, then compress. Use PNG for text-heavy designs; use JPG/WebP for photo-heavy collages.

Keep spacing subtle, avoid mixing aspect ratios, and choose formats based on content (photo vs text).

Use AllImageLab merge tools to combine images, then compress and share faster.

Tip: Resize for the target platform first, then compress. Use PNG if your design has lots of text.
