How to svg seamless pattern background generator online
- Step 1Upload your motif SVG — Upload the SVG shape you want to tile. The shape becomes one repeat unit of the pattern. Simple geometric shapes, icons, and decorative marks all work well.
- Step 2Configure the tile — Set the tile width and height (the size of each repeat unit in pixels). Adjust the rotation if you want a diagonal pattern. Increase spacing to add breathing room between motif instances.
- Step 3Copy the CSS — Copy the CSS background-image declaration and paste it into your stylesheet: background-image: url("data:image/svg+xml,..."); background-size: 40px 40px; background-repeat: repeat. The data URL encodes the pattern inline — no external file needed.
Frequently asked questions
What types of SVG shapes work best as pattern motifs?+
Simple, bold shapes tile best: dots, stripes, diamonds, crosses, small icons, and geometric forms. Complex shapes with many paths create large data URLs and are harder to tile seamlessly. A good rule of thumb: if the shape can be recognized at 20×20px, it works as a pattern tile.
Can I rotate a pattern diagonally?+
Yes. Set the patternTransform attribute to rotate(45) for a 45-degree diagonal pattern. The JAD Pattern Tiler exposes a rotation slider that sets this attribute. For stripe patterns, a 45-degree rotation on a line motif creates classic diagonal stripes.
How do I use an SVG pattern as a CSS background on a div?+
Encode the SVG pattern as a data URL: background-image: url("data:image/svg+xml,SVG_HERE"). URL-encode the SVG or wrap it in a data URI with the charset parameter. Set background-repeat: repeat and background-size to match your tile dimensions.
What is the difference between SVG pattern and CSS repeating-linear-gradient?+
SVG patterns can use any shape — icons, curves, complex geometry — as the repeat unit. CSS repeating gradients can only produce stripes, diagonal bands, and similar linear patterns. SVG patterns are more flexible; CSS gradients are simpler and require no external file or data URL.
