About this tool

Check whether a texture tiles seamlessly: drop it and see it repeated in a 3×3 grid with the seams marked, so visible edges, brightness gradients and repeating artefacts jump out immediately. Optionally apply an offset-and-blend fix to soften hard seams and download the result.

Runs on a canvas in your browser — nothing is uploaded. Useful for terrain, walls, floors and any repeating material.

How to use it

  1. Drop the texture.
  2. Inspect the tiled preview; toggle seam markers.
  3. Optionally use the seam-blend fix and download the PNG.

Frequently asked questions

What causes visible seams?

Any difference between the left/right or top/bottom edges — colour, brightness or structure. Gradients across the whole texture are the most common culprit.

What does the seam fix do?

It offsets the texture by half its size (moving the edges to the centre) and blends across the seam. It hides hard edges but can leave a soft repeat pattern — inspect the result.
