Bio Page QR codes

Every published Bio Page has a QR code that encodes its public URL, so you can take one handle from a screen into the physical world - packaging, signage, business cards, slides, badges.

Formats and sizes

The QR endpoint renders the code on demand and caches the result:

Use SVG for print - it scales to any size without blurring. Use PNG or WebP where a raster image is easier to drop in, such as a slide or a social post.

What it encodes

The QR always points at the page's current public URL, following the same precedence as the page itself - a branded domain wins, then the dedicated Bio Pages host, then the app-domain fallback. If you move a page onto a branded domain, its QR code updates to the new URL automatically; codes are cached per page and per format/size with long-lived, immutable caching for fast repeat scans.

Print tips

• Quiet zone matters: leave clear space around the code so scanners lock on. The rendered code already includes a margin - do not crop it.
• Test before you print at scale. Scan the exact asset you are about to send to the printer, on more than one phone.
• For small print (a business card), a higher size SVG keeps edges crisp even when scaled down.

• Custom domains → - put the page on your own host before printing the code.
