Seamless Pattern Studio

One square tile, drawn with a real pen. The eight tiles around it fill in as you draw, so the repeat is visible while the hand is still moving — and what you draw is vector, so it exports as a pattern swatch a designer can drag onto anything.

The stage is one square tile. Draw in it with a Wacom or any pressure-sensitive pen and the eight squares around it fill in live with the same marks: a stroke that leaves the right edge arrives at the left in the same gesture, not on lift, so you never have to imagine the repeat. Each stroke is a closed vector outline, not a raster mark — an elliptical nib whose width follows pressure through a curve you can shape, whose angle follows the stroke, a fixed dial or the pen's tilt, and whose outline is fitted to a small number of curves on pen-up. The pen's own samples are kept with every stroke, so you can select one later and change its brush, and the eraser end of the pen erases across the tile's edge the way it should.

Five repeats: straight, half-drop, brick, mirror and kaleidoscope. The tile has a real size in inches, centimeters or pixels, because a repeat sent to a printer means nothing without one. Export the repeating block as an SVG pattern that Illustrator and Figma register as a swatch, as a Level 2 EPS of flat art any RIP opens, or as an Illustrator file that opens with a named pattern swatch already in the Swatches panel — applied to a sheet or on its own — plus a PNG of the tile at print resolution. Half-drop and mirror repeats are baked into a rectangular block for you, so the file tiles in Illustrator exactly as it did on the stage.

A real pen, a vector line

Pressure sets the nib's width through a curve you shape, tilt flattens it, and a one-click calibration maps your pen's real range to the full nib. What you draw is a closed vector outline, fitted to curves on pen-up, with the pen samples kept so the brush can be changed later.

The repeat fills in as you draw

A stroke crossing the tile's edge appears on the other side during the gesture, and the eight neighbours show the whole repeat live. Dim them to see the tile alone, or drop the scrim to judge the repeat honestly.

Five repeats, one tile

Straight, half-drop, brick, mirror and kaleidoscope. Mirror and kaleidoscope reflect the overflow back into the tile, so a stroke leaving an edge comes back reflected, and the export bakes each into a block that tiles by plain translation.

Files a designer can use

An SVG pattern definition Illustrator and Figma register as a swatch, an EPS of flat art, an Illustrator file with a named pattern swatch already in the panel, and a PNG tile at 72 to 600 dpi — all from the same vector shapes.

Como usar

  1. Set the tile Pick the tile's size and units on the Tile tab and the repeat in the top bar. Four inches straight is the default; press F to fit the tile in the window, or zoom in with the cluster beside it.
  2. Draw Draw with a pen or a mouse. The Brush tab holds the nib, the pressure curve and its calibration, the tilt response and how closely the outline follows the ink. Flip the pen to erase, or press E.
  3. Adjust Press V to select a stroke, drag it, change its color or its nib, undo with ⌘Z. The Color tab holds the ink, a swatch row and the background, which can be off for a transparent tile.
  4. Export Choose the sheet — whole tile blocks or a paper size — then save an SVG pattern, an EPS, an Illustrator file with the swatch, or a PNG tile. Save the project to your account to keep every stroke editable.

FAQ

Is the seamless pattern maker free?

Yes. Drawing, every repeat mode and every export are free with no sign-up and no watermark. Everything runs in your browser and nothing is uploaded.

Do I need a graphics tablet?

No. A mouse draws at a constant width. A pressure-sensitive pen — a Wacom, an iPad with Apple Pencil in a supporting browser, a Surface pen — adds pressure and tilt, and the status bar says when a pen has been seen.

How is the repeat seamless?

By construction. Every stroke is copied across the repeat's lattice and cut at the tile's edge, so the part that leaves one side is literally the same shape arriving on the other. Nothing depends on you being careful near the edge.

Which file should I use in Illustrator?

The Illustrator file: it opens with the pattern already in the Swatches panel, applied to a sheet or on its own. The SVG also registers as a swatch and works in Figma and Affinity. The EPS is flat art for any RIP or older program.

Why is my half-drop export a wider block?

SVG, PostScript and Illustrator only repeat a rectangle by translation, so a half-drop, brick, mirror or kaleidoscope repeat is baked into the smallest rectangle that repeats that way — two tiles wide, two tall, or both. It tiles exactly as the stage showed it.

Can I use the exports commercially?

Yes. What you draw is yours, and the exports carry no license of their own.
