Best Layouts for Before/After Images

Horizontal layouts work best for before/after comparisons. Place the "before" image on the left and "after" on the right. Use consistent spacing to create a clean visual separation. For vertical comparisons (like height changes), use the vertical layout with "before" on top.

How to Arrange Images Before Merging

  • Drag images to reorder them before selecting a layout
  • Use horizontal layouts for side-by-side comparisons
  • Use grid layouts for collages with 4+ images
  • Match image dimensions for cleaner results

PNG vs JPG vs WebP for Final Export

PNG preserves transparency and quality but creates larger files. Best for graphics with text or logos.

JPG compresses photos efficiently with small file sizes. Best for photographs and social media posts.

WebP offers the best compression with excellent quality. Best for web use when browser support is not a concern.

Common Image Merge Mistakes

  • Mixing vastly different image sizes creates uneven results
  • Forgetting to set background color when using spacing
  • Choosing wrong format for the content type
  • Not checking the preview before downloading

Which format should I choose?
PNG is best for images with transparency. JPG produces smaller files for photos. WebP offers the best compression with good quality. Choose based on your needs.
