Drop in your colored art, shaded piece, or messy reference. Decalker returns a clean stencil, faithful to your linework, ready to print and transfer. No more 40 minutes in Photoshop erasing shadows by hand. A few seconds and it's on the printer. WHY DECALKER - Extraction that respects your line. The AI reads your art and isolates only the lines that matter. Shading, color, and noise disappear, original structure stays intact. - Fine tune before you print. Thicken lines, erase detail, reinforce outlines right in the app. Full control without opening another program. - Export ready for transfer. Download PNG or PDF sized to your stencil paper. Send straight to a thermal or inkjet printer. MORE THAN A STENCIL TOOL Create tattoo designs from text, mix references into one piece, try a design on skin, and refine with plain language. Everything you need to go from idea to needle. BUILT BY A TATTOOER Decalker was born inside a working studio in Manhattan, after years of solving the same problem by hand before every session. If it works for that, it works for yours. PRIVACY Your uploads are processed and deleted from the server within minutes. We do not train any AI on your work. Your authorship stays yours. SUBSCRIPTIONS Decalker Pro and Studio are auto-renewable subscriptions. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Design a tattoo with AI, try it on a photo of your skin, and turn it into a clean stencil you can print at the exact size. Describe an idea or start from a reference photo. LineSpark takes it from first sketch to transfer-ready stencil in one app, for tattoo artists, apprentices, and anyone planning their next tattoo. DESIGN A TATTOO FROM AN IDEA • Describe your idea in a few words, or start from a suggestion • Pick a style: Fine line, Traditional, Japanese, Blackwork, Watercolor, Geometric, or Auto • Choose black and grey or color • Refine it with simple edit instructions and keep every version • Make a stencil from any design TRY IT ON YOUR SKIN • Place a design or stencil on a photo of your arm, leg, back, or chest • On arms and legs it lines up with the limb and can bend with its curve • Drag, pinch, and use the side handles to set the width and height • Flip it, adjust the ink, or see a design in black and grey • Keep it in Try-ons, save it to Photos, or share it FROM PHOTO TO CLEAN STENCIL • Import from Photos, Files, or Camera • Crop, rotate, mirror, and prepare the reference • Choose Clean Outline, Balanced, or Detailed Texture • Generate one or more stencil variations • Compare the stencil with the original photo • Preview it in purple, black, red, and other transfer ink colors REFINE EVERY DETAIL • Draw and erase directly on the stencil • Adjust line weight, darkness, threshold, and contrast • Pan, zoom, mirror, undo, and redo • Keep project versions organized for later comparison PRINT AT THE SIZE YOU NEED • Set physical dimensions in centimeters or inches • Prepare A4, Letter, Legal, and 8.5 × 14-inch layouts • Tile larger designs across multiple pages with overlap • Add registration marks and a 100 mm calibration line • Export PDF or PNG, share, or print with AirPrint CREDITS OR UNLIMITED Pay as you create with one-time credit packs, or choose LineSpark Unlimited, a weekly subscription for unlimited stencils, AI tattoo designs, and try-ons (fair use applies). Available plans may vary. Failed, timed-out, or rejected generations do not use credits. Placing and adjusting a try-on uses nothing; it is charged once, the first time you save or share it. Editing stencils, reopening projects, and exporting stencils do not use credits. LineSpark Unlimited renews automatically every week at the price shown in the app until you cancel. Payment is charged to your Apple ID. Cancel anytime in your Apple ID settings at least 24 hours before the end of the current period. YOUR DATA Selecting and preparing a reference does not upload it. Cloud generation sends the prepared image, instructions, and settings only after you consent. Try-ons are rendered on your device. When you finish or leave a try-on, the photo, the tattoo, and the result are uploaded to improve try-on quality; try-ons you don't keep are deleted within 90 days. App analytics events exclude your images, instructions, project names, and email. Design it. Try it on. Print the stencil.
