Quick Tool Overview

The Image Tiler repeats a picture into a pattern and deals with the seam that normally gives tiling away. Mirroring alternate tiles is seamless by construction and works with any source; edge blending wraps and cross-fades the borders instead, which keeps the pattern's direction. Take the finished sheet, or the single tile for CSS repeat.

About the Image Tiler

Tiling turns one small image into a background of any size. The catch is the seam: unless the edges match, the repeat is visible as a grid and the illusion collapses.

Two treatments deal with that here. Mirroring flips alternate tiles so every edge meets its own reflection, which is seamless by construction and works with any source image. Edge blending wraps and cross-fades the borders instead, which preserves the direction of the pattern and suits textures like fabric, stone and paper. Set the grid, pick a treatment, and the result can be taken either as a finished large image or as a single seamless tile to repeat in CSS.

Key features of the Image Tiler

Mirrored tiling

Alternate tiles are flipped so every edge meets its own reflection, which removes the seam without touching the source pixels.

Edge blending

Wraps and cross-fades the borders to make a genuinely seamless tile that keeps the pattern running in one direction.

Tile or sheet

Download one small seamless tile for background-repeat, or the whole assembled image when you need a single file.

Grid or output size

Say how many tiles across, or say how big the result should be and let the count follow.

Live seam preview

The repeat is drawn as you adjust, so a visible seam is obvious before you download anything.

How to use the Image Tiler

  1. 1

    Load a source image

    Textures and small graphics tile best; photographs of scenes rarely do.

  3. 3

    Hide the seams

    Mirror alternate tiles, or blend the edges — mirroring is the more reliable of the two.

    Take the tile or the sheet

    Download the full tiled image, or just the one seamless tile for CSS repeat.

Frequently asked questions

Its left edge has to continue into its right edge, and its top into its bottom. Mirroring alternate tiles guarantees that for any image; edge blending achieves it by wrapping and cross-fading the borders.
