Seamless texture checker
Upload a texture and view it in a tiled grid. Hard vertical or horizontal lines at the tile borders mean the image is not seamless yet. Processing stays in your browser — nothing is uploaded to our servers.
How to check if a texture is seamless
- Upload a PNG or JPEG you plan to tile in a game engine or 3D app.
- Switch between 2×2 and 3×3 grids. Look along the red seam guides.
- If you see a hard cut, brightness jump, or mismatched pattern, the texture is not seamless — open the seamless texture generator to blend edges, then re-upload here to verify.
