A lenticular print is an image that changes or creates a 3D effect when viewed from different angles. It works by interlacing two or more images into thin alternating stripes and placing a lenticular lens sheet (a plastic sheet with tiny parallel lenses) on top. Each lens directs light from only one set of stripes to each eye, so tilting the print reveals different images — creating flip, animation, or 3D depth effects.

Our tool takes your two uploaded images and slices them into alternating vertical or horizontal stripes at your chosen width. Image A's stripes occupy even positions and Image B's stripes occupy odd positions (or vice versa). The result is a single interlaced image ready for printing. When viewed through a matching lenticular lens sheet, tilting the print reveals one image at a time.

For screen preview: 4–10 pixels works best to see the interlacing pattern clearly.
For printing: Match the stripe width to your lenticular lens sheet's LPI (Lines Per Inch). Common lens sheets are 20 LPI, 40 LPI, 60 LPI, or 100 LPI. At 300 DPI print resolution: 20 LPI ≈ 15 pixels/stripe, 40 LPI ≈ 7.5 pixels/stripe, 60 LPI ≈ 5 pixels/stripe, 100 LPI ≈ 3 pixels/stripe. Use our built-in LPI calculator in the settings panel for guidance.

We support JPG, PNG, and WebP formats up to 20MB per image. For best results, use two images with the same dimensions (same width and height). If your images differ in size, the tool will automatically resize them to match. For high-quality prints, upload images at 300 DPI at your desired print size (e.g., 1800×1200 pixels for a 6×4 inch print).

Vertical stripes (most common) mean the image changes when you tilt the print left and right. This is the standard for flip-effect lenticular prints and works with vertically-oriented lenticular lens sheets.
Horizontal stripes mean the image changes when you tilt the print up and down. This is less common but useful for certain display orientations or when using horizontally-oriented lens sheets.

This tool is optimized for 2-image flip effects. True 3D lenticular effects typically require multiple frames (8–24 images) taken from slightly different angles, which are then interlaced using specialized software. However, you can use our tool to create a simple two-view stereoscopic effect by uploading left-eye and right-eye images — this works best when printed with a matching lens sheet.

1. Download the interlaced PNG from our tool.
2. Print it at high resolution (300 DPI recommended) on glossy photo paper for best results.
3. Purchase a lenticular lens sheet matching your stripe LPI (available on Amazon, eBay, or specialty printing suppliers).
4. Carefully align the lens sheet over the print — the lens ridges should run parallel to your stripes.
5. Secure with adhesive or a frame. Tilt to see the flip effect!
