Place designs on t-shirt templates with color, size, and positioning adjustments for preview.
This generator places your artwork on a t-shirt template so you can judge a print before committing to it. You upload a design image, pick a shirt color, and adjust the design's size and position; the preview redraws as each setting changes. The thing users most often get wrong is resolution: a design that looks crisp in the preview can still print soft or pixelated, because the preview shows the image at screen size while a real print is often several times larger. Judge the composition here, but check the file's pixel dimensions against the planned print size before sending it to production.
A concrete input and expected output from the current implementation.
Input
Upload logo.png (a square PNG with a transparent background), choose shirt color black, set design size to 70%, and center the design.
Expected output
A preview of a black t-shirt with the logo centered on the shirt front, rendered at 70% of the template's default design size.
The generator composites the uploaded image onto the shirt, recolors the template to the selected color, and renders it at the size and position given by the controls, so the 70% value from the size control appears as 70% of the default design size in the preview.
The design is loaded from an image file and drawn on the shirt template, and the shirt is recolored to the color you pick. Changing the shirt color or template leaves the artwork untouched, so one upload can be tested against many colors and styles without re-uploading. The preview is rebuilt from the current settings whenever any of them change.
A size control scales the design as a percentage of its starting size, and position controls move it around the template. The preview redraws with each change, so the working pattern is: upload once, then sweep through shirt colors, design sizes, and placements until the arrangement looks right. Because this tool is a preview, not an editor, none of the adjustments modify the original uploaded image.
No. This tool runs entirely in the browser: the image is read locally, the preview is rendered locally, and nothing is transmitted. That matters for client logos and unreleased artwork, which stay on your machine unless you export or share the preview yourself.
Not exactly. The preview approximates: monitor colors are brighter than dyed fabric, fine details that look sharp on screen can soften at print size, and ink behavior on dark fabric is a production variable the preview cannot simulate. Use it for layout and composition, and order a physical sample when color matching matters.
