Make Better Comparisons
Expert tips for creating impactful before/after image comparisons.
Match Image Dimensions
For the cleanest comparison, use images with identical dimensions. The tool auto-scales mismatched images, but same-size images look most professional.
Use Consistent Framing
Keep the camera angle, position, and framing identical between before/after shots. This makes the comparison more impactful and easier to see.
Add Clear Labels
Always label which side is "before" and which is "after". Use the built-in label feature to add text overlays on each side of the slider.
Export at High Quality
When exporting the split view, choose PNG for maximum quality. Use JPG or WebP only if file size is a concern for web sharing.
