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

Notes & scope: The current release is intentionally narrow: 2×/4× upscales and CMYK exports for Postcards/A4/A3. Focus is on speed and predictable print output.

Roadmap ideas: custom sizes with bleed, more CMYK profiles, batch mode, before/after viewer.

Pricing: free tier (no sign-in). Paid plans unlock larger sizes.

Who it’s for: people who actually print (illustrators, photographers, POD sellers). If you only post online, the CMYK bits won’t matter much — but the upscaler still works fine. Happy to hear “this is useless unless it does X” feedback.
