Substack newsletter QR codes for writers — static PNG, no subscription

Substack newsletter QR codes for writers — static PNG, no subscription

Newsletter writers on Substack need readers to subscribe from print — a QR on a book jacket, conference handout, or zine back cover turns a physical moment into an email signup. Hosted QR SaaS charges ~$49/month for encoding a static URL; you can generate the same PNG locally for free.

Get your Substack subscribe URL

  1. Log in at Substack and open your publication dashboard
  2. Go to Settings → Publication details or copy your public homepage
  3. Use your subscribe link — it looks like https://yourname.substack.com/subscribe or the homepage https://yourname.substack.com

Examples:

https://newsletter.substack.com
https://newsletter.substack.com/subscribe
https://newsletter.substack.com/p/welcome-post
Enter fullscreen mode Exit fullscreen mode

Encode the full HTTPS URL. Phone cameras open Substack in the browser — one scan, straight to subscribe or your pinned welcome post.

Tip: print the QR on book jackets, conference handouts, and zine back covers so readers subscribe without typing a URL.

Why writers care

Bio links get buried. A printed QR on your chapbook, sticker sheet, or booth sign turns a glance into a subscriber — no account required for the scanner.

CSV format: one URL per line. Output: PNG files named from the row.
