You've built an archive of posts. Dozens, maybe hundreds of pieces. Your subscribers read them in their inbox, scroll through the web archive, but they can't take your work offline. Not easily.
Stack to Book changes that. Convert your Substack into a proper ebook—one your readers can download to their Kindle, iPad, or phone. Read on the subway. At the beach. Without wifi.
How It Works
Convert your newsletter
Paste your Substack URL. We fetch every public post and format it as a book.
Share with subscribers
Share the gallery link in your newsletter or download the EPUB to distribute yourself.
Readers download free
They get a beautifully formatted ebook. Table of contents, chapter breaks, the works.
Why Offer an Ebook?
- Reach readers where they already read — Not everyone wants to read in a browser or email. E-readers exist for a reason.
- Repurpose your existing content — You already wrote it. This just packages it differently.
- Zero effort to maintain — Reconvert anytime to include new posts. No manual formatting.
- Free for you, free for them — No cost, no accounts, no friction.
Join the Gallery
When you share to the gallery, readers can discover your newsletter even if they've never heard of you. It's like a public library of Substack books—and yours can be on the shelf.
