Tools for print on demand
Small tools for the dull, costly parts of printing your own designs: files that are too small, backgrounds that are not really gone, colors no ink can match, and fees that eat the margin. The free ones need no sign-up and open your images in your browser, so nothing is uploaded. That goes for the resizer, the compressor, the PNG to SVG vectorizer and the converters, which turn iPhone, WEBP and AVIF pictures into JPG, PNG or PDF. The aspect ratio calculator says which frames and posters a picture fills without cropping, and the prompt generator writes a print-ready prompt for any image AI. The upscaler runs paid AI models and costs credits.
How large an image prints, the DPI at any size, and how many pixels a photo, poster, shirt or A4 page needs.
OpenEvery Etsy fee on a sale, what is left after production and shipping, and your break-even price.
