T-shirt design to SVG
A t-shirt design lives or dies on things a web graphic never worries about: how many inks it needs, whether the background is truly transparent, and whether the edges survive being printed fifteen inches wide. Converting a design to SVG is how you get all three under control. The Single Colour preset above produces a true one-colour trace — the file a screen printer or a one-ink Merch design actually wants — with a threshold slider so you decide exactly what becomes ink and what stays shirt. Flat Logo handles the two-to-eight-colour case, and Illustration takes on detailed AI art.
The before/after slider sits on a checkerboard, so transparency is not a promise, it is something you can see. Switch on background removal and the white box around your design is gone before tracing even starts.
Ink discipline is where the palette panel earns its place. AI image generators are generous with colour: a 'simple' design can hide thirty shades. Every one of them is listed with its path count, ready to be merged into the handful you meant, recoloured to match a garment, or deleted. Fewer, deliberate colours print cleaner, cost less at a screen printer, and read better from across the street. The stats panel keeps you honest the whole time — paths, nodes and file size, live, not buried in a pro tier.
When the vector is right, the same screen exports the shirt files without another conversion: a 4500×5400 transparent PNG for Merch by Amazon, 3600×4800 for Printful and Printify, or the SVG itself for print shops that take vector. If your source is a photograph, expect a straight warning instead of flattery — photos should be printed as photos, and the Illustration preset exists for the artwork in between.
No account, no watermark, no upload. The design you have not released yet stays on your machine, because tracing runs entirely in your browser.
FAQ
What is the Single Colour preset for?
One-ink printing: screen print, one-colour Merch designs, and vinyl. It thresholds your image to a true single colour with tight corners and the fewest nodes, and the slider controls exactly where the ink line falls.
How do I get a transparent background for my shirt design?
Enable 'Remove background (solid / white)' and set the tolerance until the preview checkerboard shows through everywhere the shirt should. It handles flat white and solid-colour backgrounds.
Which export do print-on-demand sites want?
Merch by Amazon: the 4500×5400 transparent PNG button. Printful/Printify: the 3600×4800 PNG or the SVG. Both are one click from the same trace.
