Common Questions & Answers
Everything you need to know about using SplitX
How do I split an image for Instagram grid?
Quick Answer: Upload → Select 3x3 grid → Download 9 pieces → Post in reverse order (9→1).
Show detailed explanation
Upload your image to SplitX. Select 3 columns and 3 rows for a standard 3x3 grid. Drag to position. Download all 9 pieces. Post them to Instagram in reverse order: 9, 8, 7, 6, 5, 4, 3, 2, 1. Each piece should be 1080x1080 pixels. Start with a 3240x3240 source image for best quality.
What size should I use for Twitter photo grid?
Quick Answer: 1200x675px per image. Source image: 2400x1350px minimum.
Show detailed explanation
Use 1200x675 pixels per image. Twitter displays 2x2 grids (4 images max). Your source image should be 2400x1350 pixels minimum. This gives you 2x resolution for crisp display on retina screens. Upload in reverse order: 4, 3, 2, 1.
How do I create a seamless Instagram panorama?
Quick Answer: Use 3x1 layout. Upload in order 1,2,3. Add 20px bleed for seamless edges.
Show detailed explanation
Use 3x1 layout (columns: 3, rows: 1). For 3 slices: 3240x1350 pixels. Upload in order: 1, 2, 3 (different from grid posts which use reverse order). Add 20 pixels of bleed at each edge because Instagram crops slightly. Without bleed, your seams might show gaps.
Is SplitX free to use?
Quick Answer: Yes. 100% free. No account, no credit card, no limits.
