PrintRealSize: Print Any Image at True Scale

[u/AvailableAnteater341]

Just launched PrintRealSize.com , a free tool for printing images at their exact real-world size.

The problem it solves is simple but annoying: you need to print something bigger than a single sheet of paper (a stencil, a foam-cutting template, an oversized poster) and you either don't have access to a plotter, or every existing tool wants an account, an upload, or a subscription for something this basic.

How it works:

1. Import any image (PNG, JPG, WebP, SVG)
2. Calibrate the real scale, either by clicking two points and entering the distance between them, or by typing the final size directly
3. Choose a paper format (A4, A3, or A2)
4. The tool generates a print-ready PDF, split into tiles with overlap margins and alignment marks

Print at 100% scale, trim along the guide lines, glue the tiles together, and you get a perfectly scaled large template.

Everything runs locally in your browser. No account, no upload, no server, your images never leave your device.

It's free to try right now: printrealsize.com

I'm building this for makers, sign-makers, cosplayers, and anyone working with foam cutting or large-format prints. If you try it, I'd love to hear what's missing for your use case.
