Merch by Amazon: the 4500×5400 export
Merch by Amazon wants one very specific file: a transparent PNG, 4500 by 5400 pixels, at 300 DPI, in sRGB, under 25 MB. Sellers lose surprising amounts of time shuttling a design between a converter, an editor and a resizer just to hit those numbers. This page collapses that trip into one place: trace your PNG or JPG into a clean vector, fix the colours while you can see the node count, and press the Merch button for a file that is exactly 4500×5400, transparent, DPI-stamped and ready to upload.
Because the working file is a true vector, the big export stays sharp. A small, soft JPG blown up to 4500×5400 in a photo editor smears; the same artwork traced first — edges fitted as curves — renders to the Merch canvas cleanly.
Start with the right preset. Most Merch designs are flat art or AI-generated illustrations on a solid background: use Flat Logo or Illustration, switch on background removal so the shirt colour shows through the transparent parts, and watch the stats panel. If the node count is in the tens of thousands, hit Simplify before exporting — prints look better and files stay lean. The quality notice will warn you if your source is a photograph; photos belong on the shirt as PNG, not traced.
Colour control matters for print. The palette panel lists every colour in the trace with its path count, so a design that quietly exploded into forty near-identical blues can be merged back to the four you intended before it ever reaches the export button. Recolour, delete stray colours, or make the whole design single-colour for a one-ink look.
Everything runs locally in your browser — no upload, no queue, no watermark, no account — so an unreleased design never sits on somebody else's server. When the Merch file is right, the same screen gives you the Printful/Printify size and the Etsy bundle without re-tracing.
FAQ
What exactly does the Merch export produce?
A transparent PNG at exactly 4500×5400 pixels with 300 DPI written into the file, rendered from your traced vector so edges stay sharp, and comfortably under the 25 MB limit for typical designs.
Should I trace a photograph for Merch?
No — photographs trace badly in every converter, and Veclyra warns you when an image looks photographic. Keep photos as high-resolution PNG instead.
How do I make the background transparent?
Turn on 'Remove background (solid / white)' before tracing. It removes flat white or single-colour backgrounds, which covers most logos and AI shirt art.
