Substack to PDF
Substack to PDF builds a stack of posts, not one. Substack can save a single article. This takes the public feed and lets you keep as many as are still listed.
Paste https://example.substack.com. Or go straight to https://example.substack.com/feed. The homepage gets a feed lookup. The feed address does not.
Tick the essays you want together. A year of the newsletter fits, when those posts have not rolled off the feed. One essay is fine too. You are not stuck saving them one browser print at a time.
Paid posts stay paid
If the feed only shows a preview, the file only has the preview. There is no login and no paywall bypass. Subscriber-only writing stays on Substack.
The download
Each ticked post is a section, in feed order. Title, body when the page structure matches, images in that body. The publication name is on the title page. Contents and page numbers come first, so a long file is still easy to move through.
It opens in the browser. Save it, or print it.
BlogToPDF.com sits on every page. Personal reading of writing you already have permission to open. Feed patterns for other sites are listed with the other platforms.
