Pixweave – 2×/4× upscaler with CMYK print sizes (Postcards/A4/A3)

I built Pixweave to make “print-ready” upscaling simple for artists, illustrators, and POD sellers. What it does: clean 2×/4× upscales and one-click CMYK exports in common print sizes (Postcards, A4, A3) — all in the browser. Why: going from a nice web image to something you can actually print (right size, right color space) is still too fiddly for many non-technical creators. What’s different: the tool is focused on print workflow, not just pixels — choose size, get CMYK, download. The free tier works without sign-in; paid plans unlock larger limits. Would love feedback from the HN crowd on: missing sizes you rely on, CMYK expectations, edge cases (thin line art, gradients), and overall UX.
