OUR PRODUCTSMerchSwift: design merch that prints right the first time
A design app for stickers, t-shirts and mugs. It checks your artwork against print rules, draws the cut line for stickers and exports files your printer can use.
MerchSwift
Print-ready merch design. Stickers, t-shirts and mugs, with cut lines, print checks and Arabic and Latin typography.
Coming soon · iPhone, iPad and MacMerchSwift is not released yet. This page describes what we are building, and details may change before release.
What is MerchSwift?
People who make merch lose time and money on files that look right on screen and print wrong: a sticker with no bleed, a t-shirt design with a half-transparent glow that turns muddy, a cut line that the plotter does not recognise. MerchSwift is built around that problem. You design in the app, and before you export it tests the file against the rules a print shop would apply.
We do not take orders, ship products or hold stock. MerchSwift is a tool: you print wherever you like, at your own printer or at a shop you trust. Heavy work runs on your iPhone, iPad or Mac, so your artwork does not leave your device.
How it works
Pick a product
Choose a die-cut sticker, a sticker sheet, a t-shirt placement or a mug size. The canvas, bleed and safe area are set for you.
Design
Use layers, shapes, images and text. Arabic, Latin and mixed lines are shaped correctly, and text can follow a curve.
Check
The pre-flight check lists problems in plain language, such as low resolution or lines too thin to print, and offers a fix.
Cut line
For stickers, MerchSwift traces the outline of your artwork and builds a smooth cut path at the offset you choose.
Export
Export PNG, PDF, SVG or a separate cut file, or export everything the product needs in one step.
What you can make
Stickers
- Die-cut stickers with an automatic cut line and adjustable offset
- Kiss-cut stickers and sheets in A4, A3 and Letter
- A bleed of about 2 to 3 mm outside the cut line and a safe area of 2 to 3 mm inside it
- A sticker white border with adjustable thickness
T-shirts and mugs
- DTF and DTG placements: front, back, left chest, sleeve
- Transparent backgrounds and a check for semi-transparent pixels that print badly
- Wrap templates for 11 oz, 15 oz and latte mugs, with the handle zone marked
- Mockups on product photos for your listings
These are starting values. Printers and suppliers differ, so every preset can be edited and saved.
Print checks
The check runs before each export and whenever you ask for it. It looks for:
- images below about 300 DPI at the final print size, with an upscale you can run on the device;
- text or important artwork outside the safe area;
- artwork that does not reach the bleed edge;
- strokes thinner than about 0.25 mm and text smaller than about 6 pt;
- partly transparent pixels in DTF designs;
- RGB colours that CMYK cannot reproduce, with a preview of how they may print;
- fonts that cannot be embedded, with the option to convert text to outlines;
- cut lines that sit too close to the artwork or cross themselves.
Sticker cut lines
MerchSwift reads the transparent edge of your artwork, traces its outer contour, smooths and simplifies the curve, offsets it outward by the distance you choose, and removes self-intersections. The result is a clean closed path made of curves, not a staircase of pixels. In the PDF it is stored as a spot colour named CutContour, which is the name many cutting programs look for. The same path can also be written as an SVG or a DXF file.
We are testing cut-line detection with real cutting software before release. Cutters and their settings differ, so we cannot promise that every machine reads every file without a setting change. Always cut a test sticker first.
Arabic and Latin typography
MerchSwift uses the system text engine, so Arabic letters join and change shape correctly, mixed Arabic and Latin lines keep the right order, and the app itself runs right to left in Arabic. It includes a selection of fonts under open licences, and you can add your own fonts.
Output formats
PNG at 300 DPI (or the product's value), PDF with fonts embedded or outlined, PDF with a CutContour cut line, SVG, DXF for the cut path only, an optional CMYK PDF with a soft-proof preview, and mockup images for listings and social media.
On your device, and what uses a server
Background removal, upscaling to print resolution, mockups, print checks, cut lines and export all run on your device and work offline. Designs are kept on the device and can sync between your devices through your own iCloud account.
AI art is the exception. When you ask for an image, the text of your request is sent to our server, which creates the picture and sends it back. Requests for known brands, logos, clubs, characters, real people and unsafe content are refused. The details are in the MerchSwift privacy policy.
Free and paid plans
There will be a free plan with the editor and limits on exports, and paid plans that remove the limits and add cut-line PDFs, CMYK export, mockups without a watermark and more AI credits. Purchases are made through the App Store as subscriptions, and the prices are shown in the store before you buy. The terms of use explain renewals, credits and refunds.

Questions
Do my designs get uploaded?
No. Designs are edited and exported on your device, and sync through your own iCloud account if you turn that on. Only the text of an AI art request leaves the device, and only when you ask for an image.
Will the files work at my printer or cutter?
MerchSwift follows common print rules and writes standard formats, but printers and cutting programs differ. That is why every preset can be edited. Print or cut a small proof before a full run.
Can I print brand names, club logos or characters?
You are responsible for having the right to use anything you print or sell. The AI art feature refuses requests for known brands, logos, clubs, characters and real people, and our terms forbid designs that infringe other people's rights.
Does it work without a connection?
Yes. Everything except AI art, purchases and iCloud sync works offline, because it runs on the device.
Can I use my own fonts?
Yes. You can import fonts you have the right to use. When a printer needs outlines, MerchSwift can convert text to outlines on export.
