The best app to make seamless patterns depends on what you draw on: Procreate on iPad for hand-drawn tiles, Amaziograph or iOrnament for symmetry-driven designs on a tablet or phone, Illustrator or Photoshop on desktop for production repeats, and a free web generator when you just need a photo or motif turned into a tile fast. What separates them for textile work is not drawing quality but three things: which repeat types they support, how large they export, and whether you can preview the seam.
What to look for in a seamless pattern app
Almost any drawing app can make a tile if you are patient. A pattern app earns its place by doing the tedious parts for you:
- Repeat types. Block (straight grid) is the minimum. Fabric and wallpaper often need half-drop or brick, which shift every other column or row.
- Seam preview. A live tiled view, or at least an easy way to see the tile 3×3, so you catch a hard edge before a printer does.
- Export size. A 30 cm repeat at 300 DPI is about 3,543 pixels square. A 64 cm wallpaper repeat at 150 DPI is about 3,780 pixels wide. Phone apps that cap output well below that are fine for social posts but not for fabric.
- Vector or raster. Vector repeats scale cleanly to any size; raster repeats keep painterly texture but have a fixed resolution.

Best iPad apps for seamless patterns
Procreate
Procreate is an iPad-only app sold as a one-time purchase, with no subscription. It has no dedicated pattern mode, so designers combine two features. The Symmetry drawing guide offers Vertical, Horizontal, Quadrant and Radial options, and Quadrant mirrors every stroke into all four quarters of the canvas. For non-symmetric repeats, you duplicate and offset the artwork by hand so edge-crossing motifs line up. Our Procreate seamless tile setup guide walks through canvas size, symmetry and export for a print-ready tile, including how to preview the repeat outside Procreate.
Amaziograph
Amaziograph is built around symmetry. You choose one of 20 symmetries when you create a file, and whatever you draw is copied across the canvas automatically. The maker says it can export tiles for wallpaper and fabric printing at up to 4096×4096 pixels, and it runs on iPad, Android and Windows 10. It suits geometric, mandala and tessellation-style designs more than loose florals.
iOrnament
iOrnament, for iPad and iPhone, repeats each stroke according to symmetry rules drawn from crystallographic group theory, and its maker says it covers all mathematically possible types of such patterns. It is the most rigorous way to explore wallpaper-group symmetries on a tablet. The maker does not list export sizes, so test output size before you plan a fabric run.
Best phone options
Phones are good for sketching an idea and testing a tile, and weaker for production files. Amaziograph has an Android version, iOrnament runs on iPhone, and Repper has a mobile web app. Repper builds kaleidoscope and repeating tiles, offers a 14-day trial, and states exports up to 35,000×35,000 pixels in bitmap and vector formats on its membership.
For a quick, free seamless pattern generator from an image on your phone, Texloom's Seamless Pattern Maker works from any photo, scan or motif. Blend mode offsets the image and heals the seam; Mirror mode reflects it into four quarters so it tiles perfectly by construction, at the cost of visible symmetry. A live 3×3 preview shows the result before you download a lossless PNG.
Best desktop apps for production repeats
Adobe Illustrator
Illustrator's Pattern Options is the most complete repeat editor in a mainstream app. Select artwork, choose Object, Pattern, Make, and set the Tile Type: Grid, Brick by Row, Brick by Column, Hex by Column or Hex by Row, with a brick offset for the staggered layouts. Copies and Dim Copies to let you see the surrounding repeats while you edit, and the finished pattern is saved to the Swatches panel. Because the output is vector, one file serves every print size.
Adobe Photoshop
Photoshop's View, Pattern Preview makes the area outside the canvas repeat the canvas content as you paint, and Adobe notes it works best with smart objects. Once the tile reads well, Edit, Define Pattern saves it to the Patterns panel. It is the natural choice for painted, photographic or textured repeats that need to stay raster.
Krita
Krita is free and open source, and its Wrap Around Mode shows the image as if tiled, so you can paint across a seam and watch the stroke continue on the opposite edge. It does not lay out half-drops for you, but for painterly block repeats it is hard to beat at the price.
A free web option for textile repeats
Desktop apps give the most control; a web tool is quicker when you already have the artwork. The free Seamless Pattern Maker exports up to 2048 pixels on the longest side, which is enough to test a repeat or post a preview. When the tile needs to go to print, Texloom's Seamless Repeats tool in the studio adds block, brick and half-drop layouts and higher-resolution output for textile print. A free account gets you in; see pricing for plan details.

Three mistakes that break a repeat in any app
- Motifs that touch the edge without crossing it. Anything that meets the tile boundary has to continue exactly on the opposite side. Offset the tile by half its width and height and look at the center: that is where the seams now sit.
- Uneven density. A tile with a crowded corner and an empty middle prints as visible stripes or a grid, even when the seams are perfect. Squint at a 3×3 preview; clusters and gaps jump out.
- Resizing after the fact. Scaling a finished raster tile by an odd percentage can leave a one-pixel line at the seam. Decide the repeat size and DPI first, set the canvas to match, and keep tile dimensions in whole pixels.
How to choose: match the app to the repeat
- Hand-drawn florals and conversationals: Procreate on iPad, or Photoshop with Pattern Preview on desktop.
- Geometrics, mandalas and tessellations: Amaziograph or iOrnament.
- Production repeats with half-drop or brick: Illustrator's Pattern Options, or Texloom's Seamless Repeats.
- Turning a photo or swatch into a tile: Texloom's free Seamless Pattern Maker, or Repper for kaleidoscope-style tiles.
- Free painting with a tiled view: Krita.
Whatever you choose, check the tile before you send it. Export your repeat, view it at 3×3 and, if it is a half-drop, in that layout too, at 100% zoom. A seam you cannot see at thumbnail size can still show on a 1.4 m roll of fabric.
