To read Substack on Kindle, convert your newsletter to EPUB format using Stack to Book, then send the file to your Kindle via email or the Send to Kindle app. The whole process takes under a minute.
Substack doesn't have a Kindle app—no official way to read newsletters on your e-reader. You could copy-paste posts into a document, wrestle with Calibre, or just... not read on Kindle. Stack to Book gives you a better option: paste a URL, download an EPUB, send it to your device.
The Process
- 1
Find your Substack URL
Go to the Substack newsletter you want to convert. Copy the URL from your browser. It looks like "example.substack.com" or "substack.com/@author".
- 2
Paste into Stack to Book
Head to stacktobook.com and paste the URL into the converter. Hit "Convert" and wait about a minute while we fetch and format the posts.
- 3
Download your EPUB
Once conversion finishes, download the EPUB file. You can also share it to the public gallery if you want others to find it.
- 4
Send to your Kindle
Email the EPUB to your Kindle address (find it in Amazon account settings under "Send to Kindle"). Or use the Send to Kindle app. Amazon converts it automatically.
Why Not Just Use...
Calibre?
Calibre works if you're technical and patient. Download software, figure out plugins, manually fetch each post, convert formats. Stack to Book does this automatically in your browser. See our Calibre vs. browser tools comparison for the full breakdown.
Pocket or Instapaper?
Read-later apps save individual articles, not entire archives. You'd need to save each post separately. No table of contents, no book structure.
Copy-paste into Word?
Tedious. Formatting breaks. Images get weird. You'll spend hours on a newsletter with 50+ posts.
Tips for Best Results
- Public posts only — Paywalled content is skipped automatically
- Large archives take longer — 100+ posts may need a few minutes
- Images are included — But may display differently on e-ink screens
- Share to gallery — Help others find great newsletters
