Look along the lines where tiles meet — a visible seam means the texture is not seamless yet. Turn offset on to bring the edge seam into the middle.

This is a tiling preview for checking whether a texture you made for a background or pattern is actually seamless — that is, whether it can be repeated edge to edge without a visible seam. Load a single image and it's repeated in a 2×2 up to 5×5 grid, so you can see whether the left and right edges (and the top and bottom edges) line up, or whether a seam, a brightness step, or a misaligned motif appears where the tiles meet. If color or brightness changes abruptly along the lines where tiles touch, the texture isn't seamless yet. Turn on "offset (half)" and the seam that was sitting at the image edge moves to the center of the preview. This mirrors the classic workflow of using an Offset filter in an image editor to bring the seam into the middle before fixing it — a seam at the edge is easy to overlook, but one in the center is easy to inspect. Turn on "tile guides" to overlay thin lines marking where each tile begins, so you can check the pattern's continuity against the actual tile boundary. Increasing the tile count also reveals repetition artifacts — when a distinctive element stands out and makes the pattern look obviously regular — and the zoom slider lets you inspect edges closely. It's well suited to finishing noise, hand-painted textures, and AI-generated pattern assets. Your assets are your work, so this tool uploads nothing — loading and tiling all happen locally in your browser.
How to use
- Drop the texture / tile image you want to check (or click to choose, or paste with Ctrl/Cmd+V).
- Switch the tile count between 2×2 and 5×5 and watch the lines where tiles meet for a seam — an abrupt change in color or brightness.
- Set offset to half to bring the edge seam into the middle, and use tile guides and zoom to inspect edges closely. If you spot a seam, fix the source and check again.
FAQ
Are my images uploaded to a server?
No. Loading the image, tiling it, and checking the seams all happen in your browser. Nothing is uploaded, stored, or sent anywhere — everything is processed only on your device.
What is the "offset (half)" option for?
In a normal tiled view, the seam — where the image's edges meet — sits on the tile boundary, i.e. at the edge of the preview. Edges are easy to overlook, so this option shifts the image by half a tile to bring the seam into the center of the screen. It mirrors the classic step of using an Offset filter (e.g. in Photoshop) to surface the seam in the middle before fixing it.
I can see a seam — how do I fix it?
This tool is a viewer for confirming seams, not for fixing them. If you see a seam, go back to your image editor to blur or clone-stamp the edges, or offset the image and paint out the join, then check again here.
What do the tile guides show?
They mark the edge of one tile (where the next tile begins) with thin red lines. Use them to check whether the pattern continues naturally across the line, with no break or shift on it. The lines are display-only and are never baked into your image.
Can I download a file?
This tool is a viewer focused on checking whether a texture is seamless; it has no export step for a tiled image. It simply loads your original image and repeats it on screen, without editing or saving anything.
Which formats and sizes are supported?
Any image your browser can display (PNG, JPEG, WebP, AVIF, and more). Large images are automatically scaled down internally so the preview stays responsive, without changing how the seams look, and the zoom slider lets you inspect edges in detail.
