Seamless Texture Checker
Preview repeats locally in your browser. Your image is never uploaded.
Choose an image to preview its repeat.
Guide lines are visual boundaries only and are not included in the downloaded PNG. A visible join means the source edges need inspection in an image editor; this checker does not repair the source image.
How the Seamless Texture Checker works
- Choose a texture image from your device; it is decoded locally in your browser.
- Adjust the repeat count, zoom, half-tile offset, background, and tile guides to inspect different joins.
- Review the repeated preview and optionally download a clean PNG preview without guide lines.
The method
The checker draws the same source image repeatedly on a canvas so the right-to-left and top-to-bottom joins are visible. Half-tile offset moves those joins toward the center, where abrupt changes are easier to spot.
repeat preview = source image drawn at regular tile intervals
A preview can reveal visible joins and repetition, but it does not decide whether a texture is suitable for a particular game engine, render, or print workflow.
FAQ
Is my image uploaded?
No. The image is decoded and drawn in your browser. This tool does not send it to a server.
What does half-tile offset do?
It shifts the repeated image by half a tile so the edges that normally meet at the preview boundaries appear nearer the center for inspection.
Are guide lines included in the download?
No. Guide lines are display-only. The downloaded PNG contains the repeated preview against your chosen background without guide lines.
Does this tool fix a texture seam?
No. It is an inspection and preview tool. Use an image editor or texture workflow to repair a source image, then check it again here.
What image formats does this accept?
Any image format your browser can decode — JPEG, PNG, WebP, and more — since the file picker accepts general image files, not just one format.
