[{"element_type":"text","content":"\u003cp\u003eMost AI shirt generators will happily show you a nice mockup and then hand you a flattened JPG. Drop that on a black tee and you get a pale rectangle floating around your artwork. I once spent an entire evening re-cutting backgrounds in Photopea because of this.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eA transparent PNG means the alpha channel is intact, so the design sits on the fabric instead of on a box. It also matters for print-on-demand. Printful, Printify and Gelato all expect a PNG with transparency if the shirt color is supposed to show through. A JPG uploads fine, but you'll see the edge in the proof.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eWhat I check before trusting any generator:\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003e- Does the download come out as .png, or a .jpg with the extension renamed?\u003c/p\u003e\u003cp\u003e- Is it flat artwork with a clean edge, or a photo of a shirt pretending to be a file?\u003c/p\u003e\u003cp\u003e- Any watermark or \"upgrade to remove\" step at the end?\u003c/p\u003e\u003cp\u003e- Enough resolution to print — 4500px on the long side is the safe target.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eShirtCraft AI is the one I keep coming back to. You type something like \"retro mountain badge, two colors\" and it returns a design you can download as a transparent PNG. Basic use doesn't require an account, and there are no design skills involved, which is the whole point of these tools.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eIt's free at https://shirtdesigngeneratorai.com and the file drops straight into a print shop without a detour through an editor. That's a low bar, and somehow most tools still miss it.\u003c/p\u003e","metadata":{}}]
